Hominy 

One of the first food gifts the American Indians gave to the colonists,
hominy is dried white or yellow corn kernels from which the hull and
germ have been removed. This process is done either mechanically
or chemically by soaking the corn in slaked lime or lye. Hominy is sold
canned, ready-to-eat or dried (which must be reconstituted before
using). It's commonly served as a side dish or as part of a casserole.
When dried hominy is broken or very coarsely ground it's called samp.
When ground, it's called hominy grits - or simply grits - and usually
comes in three grinds - fine, medium and coarse.

Hominy grits are generally simmered with water or milk until very thick.
The mixture can be served in this mush like form or chilled, cut into
squares and fried (a.k.a. polenta). In the South, grits are served as a
side dish for breakfast or dinner.
