Joe Pesci's very funny line from My Cousin Vinny is a concise summary of the state of knowledge of my neighboring Northeasterners with regard to this delicious Southern staple. The same people who will wait in line at a fancy New York restaurant to be served some hot chef's latest polenta dish will cringe at the thought of being served grits. It sounds so common, grits. Our family owns a country inn in Newtown, Connecticut, and we can sell polenta by the ladlefuls, but can't give grits away. It has led us to this realization about the difference between polenta and grits: about $7.95.
