It's prime canning season! If you're facing a glut of tomatoes or more than ready for apple picking so you can make your own sauce, this post is for you. 

During both World Wars, home food preservation was vital to freeing up supplies of commercially canned goods for feeding soldiers and the Allies. But not everyone was used to canning at home, and even those who were experienced sometimes relied on unreliable or dangerous methods. For instance, my great-grandmother oven canned, which is no longer considered safe. And some folks still try to turn their jars upside down for a seal, which is not recommended.

All canned foods work by creating a sterile vacuum seal. High-acid foods like fruit, tomatoes, and vinegar pickled foods can be canned in a water bath, where boiling water (212 F) kills bacteria and seals the jars. Low-acid foods like non-pickled vegetables and meats need to be pressure canned. The pressure canner increases the pressure inside the chamber, which allows water to boil at a much higher temperature. This kills all bacteria, including deadly botulism, and makes the low-acid foods safe to can. 

One of the ways home economists and the federal government tried to educate people about canning and food safety was through propaganda posters like this one. Here's the advice from the poster:

"Don't can wilted, over-ripe or partly spoiled food... it won't keep."
If you wouldn't eat it fresh, you shouldn't can it. Although lots of rhetoric during the war was about saving food and preventing waste, canning can only preserve, not restore the quality of food. Poor-quality ingredients makes for poor-quality canned goods, wasting time and effort.

"Don't prepare more than your canner will hold. Food spoils if it stands around."
Canning takes time, and leaving cut fruits or vegetables lying around waiting to be put into jars makes them more susceptible to collecting bacteria or spoiling. Canning depends on sterile jars and fresh ingredients. Although it can be tempting to work ahead, time your work carefully to avoid waiting.

"Don't pack too tight... especially corn and greens. Tightly packed jars heat through too slowly."
Canned goods need to be heated through entirely to create a proper vacuum seal and prevent the growth of bacteria. Especially for low-acid foods like corn and greens, proper heating is essential to successful canning. Tightly packed jars not only risked spoilage, they also wasted fuel as it would take them longer to heat through, if at all.

"Don't lose track of time... follow timetables to the minute for successful canning."
We've all been there. That's what kitchen timers are for. While over-cooking doesn't usually hurt, under-cooking can result in improper seals. Better to use the timer and be sure. Test kitchens and home economists and scientists developed the time tables to ensure a minimum amount of time in the boiling water bath or pressure cooker to ensure adequate seal and food safety.

"Don't stand hot jars on their heads... you may break the seal."
Although some people still do this to "ensure a good seal," a heat seal is not the same as a vacuum seal, and liquids touching the tops of the cans before they are fully cooled may break the seal and allow air and bacteria in, leading to spoilage. 

​"Don't place hot jars on a cold surface or in a draft.​"
They may break or explode. Seriously. This is also why canning jars need to be heated before filling - not only for sterilization, but also to prevent shock and cracks or breakage.

​Canning can be intimidating, and certainly time-consuming, but the push to get Americans to participate in home food preservation was a hard one. Although it can be difficult to balance the effort of canning with modern lives, the urgency of food preservation during World War II meant people carved out the time to make the effort. 

Do you can at home? I usually don't have the time, although nothing beats home canned applesauce (at least, my mom's style) and jam. A friend of mine keeps me supplied with amazing homemade jams. They're worth every penny. Especially since then I don't have to do the canning myself! Share your canning memories and stories (or horror stories) in the comments!

This image was making the rounds in some of my social media art groups, so I thought I would dig into the story behind it for World War Wednesday!

Titled, "Lunch Break," and painted by commercial artist Arthur Sarnoff, the painting features a beautiful blonde woman in a red headscarf (a la Rosie the Riveter), a yellow blouse, and blue overalls using her welding torch and tongs to toast what appears to be a cheese sandwich. Another lays in her lap in a white paper wrapper, on top of her welding gloves. A green metal lunch box featuring a thermos, an apple, and orange, and another paper wrapped bundle of what appears to be more sandwiches sits on the bench before her. 

Although not quite done in pinup style, the painting is far more romanticized than, say, Norman Rockwell's "Rosie the Riveter," with her smudged face, dirty attire, and muscley arms. 

Sarnoff painted "Lunch Break" for Argosy magazine. Founded in the 1880s as a pulp short fiction magazine, by the Second World War it was shifting more towards a men's magazine, with some fiction interspersed with "true tales" of men doing heroic things. The style of art reflects that shift, with a pretty, dainty blonde using her blowtorch to make cheese sandwiches on her lunch break, rather than depicting her doing actual work. Her makeup, hair, and red-painted shaped fingernails are pristine, and the gloves in her lap look scarcely used, clean and with sharp creases still on the cuffs. 

I was not able to find a full-size image of the Argosy cover, so I don't know the date it was published. And while the badge on her overalls is large in the painting, the "words" are just gibberish brush strokes. I can only guess at its meaning. 

Although Rosie gets most of the attention, "Winnie the Welder" (sometimes also "Wendy the Welder") was in many ways more important than riveters. Women welders during the Second World War made up as much as 65% of welders in the country and were crucial to shipbuilding efforts for both warships and cargo and freight vessels. Women of all ages were thrown into welding with some cursory training, but for the most part their dedication and skill allowed them to adapt quickly to the new, often dangerous environment.

As for the toasted cheese sandwich - although aged cheese like cheddar was officially rationed, cheese was often touted as a meat substitute during the Second World War. That bread doesn't precisely look like a whole wheat Victory loaf, though! And even holding it that far away, you'd have to be quick about toasting with an oxy-acetylene torch - they can get up to temperatures of 5,600 F. 

The fantasy depicted in "Lunch Break" is mostly just that - fantasy. But regardless of its historical accuracy, it's a striking image of concepts about women, work, and food during the Second World War. 

Further Reading:

• "Rosie, Wendy, and Government Girls: The women behind the war" - National Museum of American History
• "‘WINNIE THE WELDER’: Former female shipbuilder recalls war days" - The Patriot Ledger
• "Meet Winnie the Welder" - Heinz History Center

To see some women at work (albeit in steal manufacturing, with just a glimpse of riveting and welding), you can watch the short documentary film below, "Women of Steel" (1943).

The film is an odd mix of feminism and can-do attitude mixed with patriarchal ideas of what happens "when the boys come home." What a mixed message for women to be receiving during the war! Interestingly, however, it does depict the women using a factory's cafeteria, which was probably preferable to bringing your lunch from home.

We've all had those days. Days where we forgot to bring lunch to work and can't get away to buy it, or when we bring a sad, cobbled-together lunch, or when we pick up fast food or something with empty calories. For many of us, a slow-moving afternoon or the distraction of a rumbling stomach isn't the end of the world. But during the Second World War, people didn't have the luxury of distraction of fatigue.

This bold propaganda poster from c. 1943 features a yawning male worker leaning on the surface of what appears to be a stamping or hammering machine. He says, "Ho hum," feet crossed, leaning on his elbows, as a heavy block of metal descends toward his head. The poster reads, "Avoid fatigue! Eat a lunch that packs a punch!"

During WWII, the United States engaged in total war. That meant that nearly every aspect of American society shifted toward the war effort. Nowhere was this more clear than in the everyday work of people in manufacturing. Men who weren't drafted for the war or working on farms often worked in factory settings. Factories that previously made machinery for consumer use - automobiles, refrigerators, washing machines, etc. - now found themselves manufacturing warplanes and Army jeeps and munitions. Factories worked on round-the-clock schedules, with three shifts a day. Some people worked much longer than 8 hours at a time. Although great strides had been made in ergonomics in factory work during the 1940s, the pressure of keeping up with military contracts and quotas was great. People often got too little sleep, and rationing made food supplies tight. 

During the war the U.S. federal government issued the Basic 7 - the first national nutrition guidelines ever issued. Based around the idea of balancing vitamin intake with protein, carbohydrates, and fats, the Basic 7 helped ordinary Americans better understand nutrition. Which is exactly what this poster is alluding to.

"Eat a lunch that packs a punch" was a slogan also showed up in other posters, and alluded to calcium to keep bones strong, protein to build muscles, and Vitamin A to improve eyesight, among others. But this poster focuses on fatigue, which was a very real threat to the war machine. Tired workers made mistakes, hurt themselves, and could hurt or kill others. Operating flat out didn't leave room for mistakes, and a labor shortage thanks to the draft made skilled workers difficult to replace. Unbalanced meals, or not enough to eat, did not give war workers the energy they needed to perform at the highest levels at all times. 

The pressure of wartime work must have seemed unbearable at times. And with women increasingly joining the workforce and/or managing victory gardens and food preservation at home, not to mention coping with rationing, the idea of packing a large and nutritionally balanced lunch must have seemed like a lot of extra work for people. But while cafeterias were sometimes available, most people in factory work still packed their lunches. And while working at high speeds with dangerous equipment, it was worth it to make sure you weren't going to be too tired to do your job. 

There was no room for slacking off at work during the war, and getting proper nutrition to keep in peak physical health was so important the federal government spent a great deal of money advertising basic nutrition concepts (along with lots of posters about workplace safety) to ordinary Americans. Total war meant total commitment, total effort, and total focus. Staying healthy and well-fed was all part of total war.

With all the talk of price increases and inflation these days, it's interesting to look to how these things were handled in the past. On a previous World War Wednesday, I talked about the differences between World War I and II and the "high cost of living," as it was called at the time. A big part of keeping prices affordable during the Second World War was not only mandatory rationing (it was voluntary in WWI), but also the Office of Price Administration (OPA) was able to freeze or set prices nationally for all consumer goods. Agricultural commodities were exempted from OPA control. 

Although the OPA was founded in 1941, it wasn't until 1943 that it settled on direct price control as the most effective means of regulation of consumer prices (The Oregon State Archives has a great overview of the OPA and price controls as part of an online exhibit on WWII). Although direct price control - "ceiling prices" they were called at the time - were extremely popular with the general public, retailers and especially manufacturers were constantly looking for ways around the regulations or to weaken them. The OPA used peer pressure and enlisted an army of housewives to report on those not adhering to regulations. 

This propaganda poster, one of many produced by the OPA, features a well-coiffed housewife holding a can of what appear to be tomatoes (or maybe cherries) smiling at a balding grocer, who in turn points rather wryly to a posted placard reading "OPA Price Ceiling List." The text of the poster read "Let's TEAM UP to keep food prices down for the sake of America's Future." 

Ceiling prices were published by the OPA and required to be posted in retail spaces, especially food, which was among the most price-controlled area of American life. Although small businesses could charge slightly higher prices than regional chains, the prices often differed by only a few cents, and were designed to help out the small businesses by giving them slightly higher profit margins. Much of the propaganda around price control and rationing both calls for cooperation between retailers and consumers, and this poster is no exception. Retailers were expected to follow regulations and consumers were expected to only patronize retailers who were following the rules. 

That didn't stop a huge black market from developing, especially around meat. Despite massive quantities of meat being used to feed the armed forces and sent overseas to support the Allies, ranchers and meatpackers were unhappy with price controls and in the aftermath of the war some actively withheld meat from the market in an effort to create false scarcity and anger voters, who would oppose the price controls. By the fall of 1946, meat production had fallen by 80%. Angry voters blamed the party in power - the Democrats - rather than the ranchers and packers who were colluding to manipulate the market, and delivered a Republican win in the election of 1946 - the first since 1930. 

The tension between food producers and food consumers has a long history. In the "free" market, farmers and ranchers are rewarded for low yields and production because prices go up. Getting producers to produce enough to feed people affordably while still ensuring they make a fair profit is a dilemma that plagued the early 20th century. Finally, during FDR's New Deal, government funds were used to subsidize farmers through low-interest farm loans and also direct payments to steady the supply on the market and protect farmland from the Dust Bowl. These were revoked in the 1970s under Nixon's Secretary of Agriculture Earl Butz of "get big or get out" fame. Instead, the government maintained an agricultural price floor - if the market price fell below the floor, the government would make up the difference to the farmer. So what happened? Of course prices instantly fell below the floor - because they could. Food manufacturers benefitted from purchasing commodity crops for less than they cost to produce, our modern processed food production flourished (to the detriment of our health), and taxpayers footed the bill. 

In the modern era, many economists (including at NPR) have used the jump in post-war inflation as the OPA was dissolved wholesale (instead of gradually increasing prices as economists of the period recommended) as proof that the OPA was always a bad idea, doomed to failure. But the people who hated the OPA the most seemed to be the people who stood to profit the most from inflation - the manufacturers, packers, and retailers who could pad their bottom lines with price increases in the name of "scarcity." 

Sound familiar? It seems to me as though the OPA, behemoth bureaucracy though it was, was more the victim of those determined to see if fail, at all costs, than a violation of the "natural order." Because although economists like to talk about scarcity driving up prices, they have very little to say about price increases that are not caused by scarcity, and even less to say about price increases on goods that people cannot afford to do without - like food and housing and healthcare. 

The tension between pro-business forces who oppose regulation and pro-consumer forces who support regulation date back to the 19th century in the United States. The conflict was present in the fallout from the Panic (and subsequent 7 year Depression) of 1893, in the industrial recessions of the early 20th century, and especially in the handling of the Crash of 1929 and subsequent Great Depression. FDR's New Deal and a dramatic increase in government regulation of business and the economy helped pull us out of the Depression (wartime defense spending didn't hurt either). But the OPA caused a strong negative reaction among the pro-business, anti-regulation groups that shifted politics back toward the myth of the "free" market. But while inflation did increase by as much as 20% after the OPA was dissolved, strong postwar wages helped mitigate the effects. Whereas wages in the modern era have largely stagnated for over a decade, especially for workers on the lower end of the economic spectrum. A few economists have discussed the morality of price gouging, but should we rely on the morals of businesses in a capitalist society? 

The tensions between pro- and anti-regulation forces are still at play in modern politics. After decades of deregulation, the Biden Administration has begun re-regulating or executing new orders on the environment, consumer protections, and immigration, but has yet to address the modern "high cost of living," although it is trying to reduce meat monopolies. But corporate consolidation has continued unchecked for decades, belying the "free market" and hurting consumers. It's a problem that won't be solved overnight.

As prices for housing, food, healthcare, and other essential goods continue to rise, will we return to the lessons of the Office of Price Administration? That remains to be seen. I, for one, wouldn't mind a return to the "fair price" lists published in WWI. If politicians can't stomach a return to government regulations, maybe we can at least shame food corporations into sacrificing some of their record profits to ensure Americans have enough to eat.

Previously, we met Jack Sprat and his wife in a fairytale cartoon propaganda poster. This week, we go all out total war with Walt Disney. 

Produced by Disney in 1942, "Food Will Win the War" was a propaganda film of the Agricultural Marketing Administration, under the auspices of the United States Department of Agriculture. Narrated like a newsreel, the cartoon illustrates the might of American agriculture, in brilliant technicolor. 

The cartoon illustrations of the overwhelming productivity of American agriculture  compare mind-boggling production numbers to well-known landmarks and other Very Large Things. Flour to blizzards, bread to the Egyptian pyramids, tomatoes to the Rock of Gibraltar, cheese to the moon, etc. When getting to meat production, we get to see the Disney's Three Little Pigs, leading a parade of hundreds of hogs, playing "Who's Afraid of the Big, Bad Wolf?" on fife and drum. Periodically, we are reminded that the size of several of these items could crush Berlin, including a very plump blonde representing American fat and oil production. One scene compares American agriculture to a giant bowling ball, which is depicted rolling through Nazi headquarters (tattering the Nazi flag in the process), and bowling over pins caricaturing Adolf Hitler, Benito Mussolini, and Emperor Hirohito.  The film closes with a grim montage of the challenges faced by shipping and a call to the Four Freedoms outlined by FDR - Freedom of Speech, Freedom of Religion, Freedom from Want, and Freedom from Fear.

Like many propaganda films and newsreels from World War II, this one has plenty of bombast, with good and evil portrayed in stark black and white terms (even though the animation is in color). Released to American audiences on July 21, 1942, it had several goals. One was to buoy American confidence in food supplies. There were concerns that the U.S. was shipping too much produce overseas and that there would be shortages at home. These concerns were not unfounded, but wartime production increased enough that even though rationing eventually grew tight, everyone had enough to eat. Another was to impress upon foreign audiences that American production capacity was overwhelming and would strengthen the Allies, who had been at war for over two years already. 

In 1941, Disney was suffering major financial losses from Fantasia - it was a box office flop and made just a fraction of what it cost to produce. You can see the economy of animation in many of the scenes of this film - where largely still images move across the frame or zoom in or out - achieved by layering cells. 

But the success of Disney's animated films for the war effort helped keep the studio afloat during the war. They became well-known in particular for training films, as Disney animators were able to illustrate in fine detail mechanical operations and theoretical scenarios that would be difficult or impossible to film in real life. Some speculate that without World War II, Disney Studios might have gone under after only a few films.

It's been cold and snowy lately here in the northeast, and sometimes you just have to have soup. But going to the grocery store in a snowstorm is ill-advised. This recipe lets you use up all kinds of bits and ends that might be languishing in your refrigerator. 

This particular recipe is my own creation, based on what was in my kitchen, but is entirely inspired by history. Several parts of history, in fact.

The first is reducing food waste. Historical peoples did not throw out potatoes just because they were starting to sprout, or lettuce because it was a bit wilted, and neither should you. Putting lettuce in soup is also extraordinarily historic, and a practice that should be revived. 

Another is that this recipe is based on one of my favorites, "Green Onion Soup," from Rae Katherine Eighmey's Hearts & Homes: How Creative Cooks Fed the Soul and Spirit of America's Heartland, 1895-1939 (2002). Eighmey read hundreds of agricultural magazines and gleaned recipes and wisdom from the farm home sections. Found in the December 26, 1924 issue of Wallace's Farmer, Green Onion Soup is a unique recipe. A combination of simply green onions and potatoes, the soup is cooked in a small amount of water, and then partially mashed right in the pot without draining. Cream and milk are added to thin the soup and add richness. The soup is comforting and nourishing and retains all of the vitamins and minerals that might otherwise be lost by draining away the cooking water. 

Which brings me to the final inspiration - vitamin retention in the style of recipes from World War II. By cooking the vegetables in the water that becomes the broth, you lose far fewer nutrients and flavor. Plus, other aspects of the soup are also quite appropriate to WWII - it's meatless, in line with rationing, and makes good use of milk, a favorite 1940s ingredient. 

I had a number of foods that needed using up that made their way into this soup: a few red potatoes, a head of wilted red lettuce, the fresh bits of baby spinach out of a box that was on the verge of getting slimy, a whole celery root starting to go a bit soft, some garlic starting to go green in the middle, and the tail end of a gallon of milk. The only fresh addition was two bunches of green onions. You could modify it pretty much however you want - any kind of greens, any kind of onion, any kind of root vegetable. 

4 red potatoes
2 bunches green onions (scallions)
1 celery root
3 cloves garlic
1 head red lettuce
1-2 cups baby spinach
water
salt
pepper
1/2 cup half and half
1 cup buttermilk
whole milk

Scrub and dice the potatoes, cutting away any eyes or bad parts, but leave the skin on. Slice the green onions, white and green parts. Cut away the knobbly skin from the celery root, then cut into small dice. Mince the garlic, wash and chop the whole head of lettuce. Add it all, with the spinach to a large stock pot and add water not quite to cover. Add at least 1 teaspoon salt (I used wild garlic flavored crystal salt languishing in a drawer) and bring to a boil. Reduce heat and simmer hard until all vegetables are very  tender and potatoes fall apart when pierced with a fork. Do not drain. Using a potato masher or sauce whisk, mash vegetables in the pot until blended with the water, leaving some chunks. 

Add a the half and half and buttermilk (or you could use part heavy cream, or leave out the buttermilk, or just use milk) then add milk to thin out the soup and to taste. Taste for salt and add more if necessary, along with pepper and whatever other herbs and spices you like. Serve nice and hot with buttered bread or toast. 

The buttermilk does add a nice, distinctive tang. If you don't have any, add a dollop of sour cream, or some plain yogurt, or a splash of lemon juice.

You could make this vegan with plant-based milk and butter. For a different flavor, add whatever fresh herbs you have lying around - dill, parsley, basil, and cilantro would all be good here. Add vegetable broth and some lemon juice instead of milk for a bright, brothy soup instead of something creamy. Use sweet potatoes or squash and tomato broth with the greens. The possibilities are really endless. 

If you'd like more interesting recipes, you can purchase Eighmey's book from Bookshop or Amazon - either way, if you do, your purchase will support The Food Historian!

White Christmas (1954) is probably one of my favorite holiday films. I did not grow up watching it. In fact, my husband was the one who introduced me to it, but I fell in love. It's got everything - WWII, great relationships, music, dancing, everything wonderful and awful about putting on a show (former theater nerd, here), and of course, a heartwarming tale in a beautiful setting. Not to mention Bing Crosby's velvet voice. 

So when a friend, who had never seen White Christmas, suggested I make a dinner menu to go along with the film, I couldn't resist. She knew I'd done similar menus before (Star Wars and The Hobbit, respectively, both birthday parties I threw myself), but this one was fun because I could delve into all my vintage cookbooks for ideas.

Now, there are a few foods mentioned or shown in the film. One of the first (and best) is the scene in the club car on the way to Vermont. Mentioned or shown foods include:

• club sandwiches
• popcorn (on the bar)
• lemonade
• malteds (like a malted milkshake)
• hot buttered rum
• coffee

You can see for yourself in this clip:

The other major scene is after hours, when sandwiches and buttermilk are the order of the day. Mentioned or pictured in this scene are:

• buttermilk
• ham and cheese on rye
• turkey sandwich
• liverwurst

I based my recipes largely on the foods of the late 1940s, focusing on New England recipes. Because although White Christmas was released in 1954, and clearly takes place in the 1950s, it was influenced by the earlier (and slightly more racist) Holiday Inn, which came out in 1942. In addition, the WWII connection between Bob and Phil (a.k.a. Wallace & Davis), made me think this menu needed a little bit of a 1940s flavor. 

Here's the menu:

• New England Lemonade
• Grapefruit Salad
• Vermont Parsnip Chowder
• Vermont Graham Muffins
• Lentilwurst Sandwiches 
• Malted Milkshakes
• Maple Sirup Gingerbread

No, those aren't typos - "lentilwurst" is what I call vegetarian liverwurst and while everything was good, that was the surprise hit of the night. I wish I had made a double batch because it was gone almost instantly. Maple Sirup (also not a typo - that's how they spelled it in the cookbook) Gingerbread was another delightful (if rather expensive) hit. Thankfully, we did not eat the whole cake in one sitting, although two days later we're down to the last piece. 

In an effort to spare you from the world's longest blog post, I'm going to be posting the recipes each day this week (probably more than one per day) as their own blog posts. Don't worry - I'll link them back here as they're posted so you can always find everything in one spot. You should get the whole menu before the weekend - just in time to plan a White Christmas Dinner and a Movie of your own! Happy eating!
