A staple in our home. Brown up a good thin gravy (bacon greese works best), beat up 1 to 2 eggs, depending on amout of gravy. Pour the egg slowly into the gravy, I start at edge of pan and pour in circular manner ending in the middle. Don't stir the gravy, for now, let the egg "set" and firm up over medium heat. You want lumps of eggs, so once the egg as "set" you can break it up into the gravy and stir. Plenty of Black Pepper should be added. Love it on a Biscuit.
Secret: Thin gravy, the egg will thicken it. Don't stir too soon after egg has been added. Two eggs to a small amout of gravy is excessive.
