In a skillet, heat your oil or grease over medium heat. If you want it to taste mild, use oil. If you want it to have a stronger pork taste, use some bacon grease. I like to use a little of both. How much you use will depends on how many wieners you have. For 2 wieners I use about 1 T. of oil, 1 T. of bacon grease and 2 T. of flour (later in recipe). Slice wieners into coins into grease. Fry until desired crispness...I like mine about half crispy. Sprinkle flour on top of wieners and stir (should be the consistency of wet sand) and fry for a few minutes until flour starts to get a nice tan color. A little at a time while constantly stirring, add your liquid. If you want a stronger taste, use water. If you like a creamier taste, use milk, or some of both. How much will depend on how much grease you started with, but for what I've told you already will probably be around 2 cups. Cook and stir until bubbly and desired thickness. Season with salt and pepper. Serve over biscuits, toast or your favorite bread.
