Once you have your biscuits prepared, you will need a large skillet. In the skillet over medium/high heat you will want to add your favorite breakfast sausage. I used a 1lb log of mild breakfast sausage.
Next you will want to break it up and brown it. Very similar to making chopped meat.
Once the sausage is browned you will want to add 1/3rd cup of flour. Mix in and cook for 1 minute.
Once the flour is cooked, add three cups of milk. Stir.
Add the seasonings, stir and bring to a boil.
Once it starts to boil, reduce the heat and simmer until the sauce is the consistency that you desire. I like a smooth but thick gravy. I let mine simmer for 5 minutes after the boil.
Serve the gravy over the freshly baked biscuits.
