Along with all the changes wrought by the Industrial Revolution came the manufacture of metal kitchen gadgets, making the lives of home cooks easier. “Labor saving” applied to factory plants starting in 1791 and caught up to the home in the 1850s, with the eggbeater leading the kitchen evolution and revolution. In the last half of the 19th century, 692 separate patents were issued for newfangled eggbeaters alone.
Among these, the enduring wire whisk allows a cook to hold the bowl with one hand and whip with the other, whereas two-handed rotary beaters sent later lightweight bowls skittering. Electric mixers of various kinds followed, leading to Carl Sontheimer’s invention of the Cuisinart in 1973.
