Rival 6 Quart Electric Ice Cream Maker...For a century and a half, since a woman in New York invented the hand-crank freezer, making ice cream has been an American family value. Mom blended the ice cream mixture; Dad filled the maker's wooden tub with ice and rock salt to achieve the below-freezing temperature needed to produce smooth confections; kids clamored to turn the crank; and everyone happily consumed big bowls of ice cream as a reward. This family-bonding activity remains as vibrant today as it was through a century-and-a-half of "progress."
