Think twice before buying another “convenience.” In an episode of Cathy Guisewites comic strip “Cathy,” the kitchen equipment of the 50s shows a pan, a spoon and a knife. Out of it came a typical Sunday dinner of roast chicken, mashed potatoes and gravy, stuffing, salad, two vegetables, homemade rolls and an apple pie. It then show the standard equipment of the 90s: food processor, bread maker, pasta maker, juicer, rice steamer, laser-cut European knife system, 20-piece cookware set. The typical Sunday dinner of the 90s? Microwave pizza.
