The first Cuisinart food processors were made by the company that made the big ones for commercial kitchen use.
Mark has experience with cakes from world famous chefs, but somehow, I would think that in the chef's kitchen, there would be assistants who would do some of the tasks that were done by hand. I don't see why a chef would feel that a cake prepared, at least partially, with a mixer would be inferior. Some baking experts do say that they fold in the flour by hand and that's great. I don't get paid to bake and I am doing baking when I can squeeze it in with all of the other stuff so I mix a cake start to finish in a mixer, but I don't use a "box mix." I also wash clothes in a washing machine and use the dryer to dry them. Electric mixers certainly improved cakes made in the home because they eliminated the variables in the amount and quality of the mixing, based largely on the strength of the person preparing the batter, or the strength of others who could help. Julia Child used the mixer and some of her guests on "Baking With Julia" used the mixer. My mother would only make Angel Food cakes by hand with a spoon-shaped whisk. She thought a mixer toughened the cake, but she is not one who is anxious to try any new method or equipment. I remember the tiny bit of almond extract she added to the cake. The first time I smelled original Jergens hand lotion, I thought of Angel Food cakes.
