Barbecued Lamb on Skewers

2 pounds stewing lamb, cut in 1 1/4” cubes
4 tablespoons fresh lemon juice
3 cloves garlic, minced
1 tablespoon hot chili oil (or 1/2 teaspoon cayenne and 1 tablespoon salad oil)
1/4 teaspoon salt
1 pinch sugar
Combine all ingredients and marinate lamb cubes for 2 hours in covered bowl. Drain lamb, reserving marinade for basting during barbecuing. Skewer lamb; you should have enough for two skewers per serving. Barbecue until browned, but still juicy. Overcooking will dull flavors. Serve with nang (Moslem bread) or shao bing (baked sesame rolls).Makes 4 servings
