Ok - here's mom's tried and true recipe- we stole it and make it at camp in the fall.
For five man sized servings ( we serve it over pancakes and biscuits)
1 lb. ground sausage
2/3 cup milk (use 1 cup if the gravy will sit for a while)
1/2 to 1 teaspoon butter (the real kind)
salt and pepper (black&ground) to taste.
1-2 tablespoons flour
Brown the sausage and drain off grease, stir in milk, butter, and 1 tablespoon flour. Simmer for 5 minutes and add salt & pepper for taste. Let stand. If after 5 minutes the mixture isn't thickening, add 1 more tablespoon of flour and simmer for 5 minutes again.
Here's the key if you're going to make it, refridgerate it and then reheat. Reheat it with 1/4 to 1/2 cup milk, NOT water. Water will make it taste , well, watery. Also - I use the same pan I browned the sausage in to make the gravy. If you transfer the meat to a clean pan you'll miss the taste of the drippings and the gravy will be cardboard
Also - I like to add Old Bay seasoning.
Best of Luck
