Refrigerator
Arguably no technology has changed our cooking and eating habits more than this now-ubiquitous home appliance: Without it, we would still be getting regular deliveries from the iceman and the milkman and making daily trips to the butcher’s. Preserving and pickling would be essential ways of life instead of newly rediscovered culinary trends, since perishable foods only lasted about two or three days in an icebox. While the first home refrigerators debuted in the 1910s, mass production didn’t begin in earnest until the Depression; fridge ownership nearly doubled during the WWII years, reaching 85 percent of American households by 1944. Today it’s at 99.9 percent.
