My
dad was in the army for
24 years and my mom use to make this for him. I love the stuff. The navy uses chipped
beef but I prefer the hamburger version.
Here is an official U.S. Army recipe for SOS:
CREAMED BEEF ON TOAST (SOS)
1/2 lb. ground
beef
1/4 tsp. salt
1/4 tsp. pepper
4 tbsp. sifted flour
1 cup evaporated
milk
1 cup water
2 tbsp. butter
Brown ground
beef in its own fat. Remove excess fat and save for making roux. Season with salt and pepper. To make roux, place 2 tbsp. reserved fat in double broiler or heavy pan. Slowly add sifted flour, stirring constantly over low heat until thoroughly blended. Cook for five minutes. Do not brown. Combine
milk and water. Add butter and scald (not burn) in double broiler or heavy pan. Add roux to scalded
milk, stirring constantly until thoroughly blended. Add meat mixture and cook about 10 minutes, or until desired consistency. Serve on toast.
