World's Best Grilled Pork Tenderlon

Putting this recipe here because I thought I had lost it, and thought seriously upset me.This is by far the yummiest recipe ever! 
GRILLED PORK LOIN
2 1/2 - 3 lb. boneless pork loin, split lengthwise
1 tsp. ginger
1 tsp. dry mustard
1 c. soy sauce
1/2 c. sherry
1/4 tsp. garlic powder
1/2 tsp. salt

Combine soy sauce, sherry, salt, ginger, dry mustard and garlic powder. Place pork loin in a bag. Pour marinade over pork; cover and marinate at least 2 hours, turning the meat occasionally. I like to marinate overnight if possible.

Place loin on grill 6 to 8 inches above low coals. Grill 1 to 1 1/2 hours, turning frequently. Brush with marinade several times during cooking. To serve, cut in thin slices. Makes 4 to 6 servings.
