Hmm... Not sure about your tastes, but mine(working from memory):
Break up & Brown a tube of hot sausage. Drain fat into a bowl or something.
Gravy: 2 cups milk, 2 tbsp of corn starch (or 4 tbsp of flour), 2-4 tbsp drippings(or butter).
Mix the milk, drippings(or butter to make up if your sausage is lean), flour, and fresh ground pepper(about a tbsp, but to taste) in a pot of suitable size. One of those springy whisks is good. Mix it up good.
Turn up the heat to high, and you have about a minute before you need to be stirring constantly, and I mean constantly. Once it's boiling 'rapidly' and shows some signs of thickening, turn the heat down/off, and add the sausage, switching to a big spoon for stirring. Keep stirring until it stops boiling. Serve with biscuits.
