I ate a small mountain of SOS in various mess halls. This recipe isn't bad but its not authentic USMC SOS. I added diced onion, garlic powder, worchester sauce and a dash of hot sauce. That is the taste I remember! SOS is normally served over toast but is best served over biscuits. Try it the authentic way, thousands of US service men have eaten it that way.  -  29 Jul 2007  (Review from Allrecipes USA and Canada)

Make this way for great results: 1. In a Large Skillet brown 1 pound of VERY LEAN ground beef. 2. Turn OFF heat. 3. Add to the cooked beef: 1/4 cup softened butter, 1/2 cup flour, 2 tsp. instant beef bouillon granules, salt to (to your taste), ground pepper (to your taste). REMEMBER: at this point to stir all above until flour is completely absorbed, only then can you turn on the heat at medium high. 4. Then immediately add the milk and Worcestershire sauce in these amounts: 4 cups milk 1/2 tsp. Worcestershire (optional) 5. Cook and stir until thickened. Serve on biscuits or toast and sprinkle real bacon bits on top if desired  -  26 Feb 2008  (Review from Allrecipes USA and Canada)

This recipie although somewhat tasty is not the USMC SOS recipie. Wherw is the onions, garlic Worcesttershire Sauce, Soy Sauce? The "REAL USMC SOS" contains these ingredients.  -  10 Nov 2006  (Review from Allrecipes USA and Canada)
