What exactly is hominy? Hominy is dried corn that has been soaked in a lime bath. You've had hominy before, though, because in it's ground form it's used to make tortillas and grits. The calcium in the lime makes it possible to transform the dried corn into masa which is the base for tortillas. It has the distinct taste of corn, and you'll find the cans in the Mexican section of your grocery store. Recipe courtesy Food Network Magazine
