Cook sausage in large skillet until it's dark brown (no pink) - do not drain or rinse! Leave it in the skillet.
1 pound sausage
Sprinkle 2 tablespoons of flour over the sausage; stir; add ¼ cup of milk; stir
6 tablespoons flour, 2½ cups milk
Repeat process in the same measurements until all 6 tablespoons of flour and the 2½ cups of milk are gone
Season with salt and pepper
1 teaspoon salt, 1½ teaspoons pepper
Serve immediately
Notes
Note:If you're ground sausage is frozen you can either thaw it in a bowl of cold water or put it in a skillet frozen; it's okay to "thaw" ground meat in a skillet when it's frozen.
