4 c. soy sauce (the heavy dark imported kind is too strong)
1 c. packed light brown sugar
1 tsp. garlic powder
1 tsp. onion powder
8 tbsp. fresh lemon juice
4 tsp. ground ginger
1 skirt steak (about 3/4 inch thickness) for every 3 persons
Warm flour tortillas

Combine soy sauce, brown sugar, garlic powder, onion powder, lemon juice and ginger in a jar; shake to mix well and dissolve sugar. Let marinade stand in sealed jar overnight. Pour marinade over beef and let marinate 2 hours or overnight in refrigerator in sealed container. 1 quart marinade.

Remove fajitas from marinade and grill over very hot coals a short time, about 10 minutes per steak if meat is 3/4 inch thick. Brush meat with marinade two or three times while cooking.

Refrigerate extra marinade in tightly sealed jar for future use. Chop meat with a cleaver and wrap in warm flour tortillas to serve.
