Here's one recipe variation that kept the troops moving! Creamed Beef Style S.O.S.
2 lbs pound ground beef
1/2 cup white flour
1/4 teaspoon ground black pepper
3/4 teaspoon salt
2 tablespoons lard or bacon grease
2 tablespoons Worcestershire Sauce
4-1/2 cups whole milk
1 onion, diced, any variety will work
1 jalapeño pepper, diced
8 slices white bread, toasted
Crumble ground beef in large pan. Brown beef over medium high heat, until meat starts to brown, about 6 minutes. Add diced onions and jalapeño peppers, and cook another 5 or 5 minutes, until beef is browned and diced onions are translucent. Remove from heat. Drain most of grease, but leave a small amount of grease in the pan for flavoring; about a tablespoon. Add lard or bacon grease. Return meat mixture to medium heat.
Add flour to meat mixture and stir until flour is cooked, about 2 minutes. With the mixture still in the pot, add milk and Worcestershire sauce. The flour will naturally thicken the sauce. Cook for about 10 minutes, stirring constantly, until ingredients are well blended and the sauce has thickened to about the consistency of runny pancake batter.
