2 1/2 to 3 lbs. sirloin tip roast
1 tbsp. soy sauce
1 tbsp. fresh ginger, grated
1 stalk green onion, chopped thinly end to end
1/8 tsp. Dashi-no-moto (Oriental soup base)
1/2 c. Sake or dry sherry wine
1 or 2 cloves garlic, thinly sliced

Preheat oven to 375 degrees. Trim off all fat from the meat. Make cuts in several places on the surface of the meat and insert a piece of garlic in each cut.

Rub meat all over with soup base powder and place on a sheet of heavy duty foil. Place ginger and green onions on top of the meat, add soy sauce, and finally pour over the sake or wine. Seal the meat with foil.

Place wrapped meat in roasting pan and pour in a little water. Bake 1 hour. Remove, unwrap meat carefully and slice. Set aside.

Make gravy with juices strained from meat, adding 1/2 teaspoon soy sauce. Serve meat with hot mustard and gravy.
