Egg Gravy

This is probably my family's favorite breakfast. My husband, sons, grandchildren and siblings all love it. It is always on the request menu when they come to visit..or if I visit them! My husband's mother taught me to make it, and like most of my "home cooking" recipes, ingredients are approximate because they are "a little of this, and a pinch of that" recipes that were handed down verbally, and by my watching in the kitchen. It might not sound very good, but it is delicious, and perfect for a cold morning!
Ingredients:
3-4 TBS BACON drippings
3 TBS flour
3 C milk, approximately
2 eggs
Salt and pepper to taste

Instructions:
Stir flour into drippings until well blended. Cook for 2 to 3 minutes, until bubbly and a light brown. Gradually add milk, stirring with whisk. Cook until thickened and creamy, stirring constantly. After gravy begins to thicken, break eggs into it, stir until eggs are cooked. Eggs will thicken gravy, so you will have to add more milk or water. Season with salt and pepper to taste. Making gravy takes practice. Rarely does anyone get it right the first time. If it is lumpy, keep whisking; if too thick, add some water/milk. Above all,do not panic! Serve over hot biscuits or toast made in the oven.
