Preheat the oven to 350 degrees.
Slowly cook the grits in boiling water for 20 minutes. (If you use instant grits, do not cook 20 minutes. Cook according to package directions.) Add the butter, cheese, salt, Tabasco, eggs and Worcestershire sauce. Pour into a buttered casserole.
Bake for 1 to 1 1/2 hours or until puffed, golden, and set in the middle.
