World War II saw many culinary inventions born out of necessity. In 1942, the United States government began rationing foods that were once household staples like meat, fats, and cheese, and as a result, many resorted to imaginative substitutions and new recipes that relied less on ingredients that had become scarce.
While some of these stuck around long after the privations of wartime had ceased — boxed mac and cheese, for example, became a national craze during World War II because it required very few ration points — others definitely remain products of their time. A perfect example of the latter is a spaghetti recipe that your grandma might have eaten, but would strike you as thoroughly different from any pasta dish we'd recognize today.
