1629, first recorded by Capt. John Smith, probably from Powhatan (Algonquian) appuminneonash "parched corn," probably literally "that which is ground or beaten." See grits.
kernels of corn, either whole or ground, from which the hull and germ have been removed by a process usually involving a caustic agent. Hominy was traditionally prepared by boiling the corn in a dilute lye solution made from wood-ash leachings until the hulls could be easily removed by hand and flushed away with running water. In the modern commercial technique, the corn is boiled in dilute sodium hydroxide, and the hulls are removed by the combined action of rotating cylinders and running water.
