Preparation Bring 4 cups water to a boil in a 4-quart heavy saucepan and stir in grits and salt. Return to a boil, stirring frequently. Reduce heat and simmer grits, uncovered, stirring occasionally, until very thick and most of water is absorbed, about 10 minutes. Reduce heat further and cook grits at a bare simmer until cooked through, about 1 hour 10 minutes, stirring frequently and adding remaining 1 1/2 cups water (1/4 cup at a time) whenever grits become very thick. Add tasso, butter, and salt and pepper to taste, stirring until butter is melted.
