My Grandma used the grease off of what ever meat she cooked for breakfest that day. She would cook Beacon, Side Pork, Ham or Sauage each morning and that is the grease she would use for the gravy. She would use three tablespoons full and enough Flour to make a past and cook it a bit to cook the flour. Then she would add milk until she got it right then cook it until it was thick as she wanted it. Adding Pepper and Salt to taste. Boy is that good stuff. I would be hungery right now but I am eating a big bowl of grits and side meat Ron
