Have been doing this for years. I use only one pan however. When sausage is thoroughly cooked - I remove it to a paper plate... Add a little oil to the pan, then add the flour until a thickened brown roux or sauce... Add back the cooked sausage & broth (beef or chicken) use liquid broth instead of bouillon and continue... Have even added chopped onion and cook with the sausage. You will lock the door and not answer to anyone... When you are eating this served over hot biscuits. Is outstanding!
