A couple of pedantic responses... grits are typically a southern U.S. dish, but even in that part of the country the taste for grits is dying out... due in large part to their tastelessness. They require a lot of butter or other additions to make them palatable.
Secondly, grits are quite disctinct from hominy... grits are simply rather coarsely ground corn whereas hominy (either white or yellow) is preserved whole corn kernels with the outer shell removed through a bath usually made with wood ashes. One can either home can it or it can be purchased in cans. It, too, is an acquired taste originating in the South...
