   1      small         onion; chopped
     1/4  teaspoon      ground cloves
   1      tablespoon    brown sugar
   1      teaspoon      chili powder

Preparation:

Combine all sauce ingredients in a pot, place over medium heat and boil until reduced to a thin syrup. Pour the syrup through a strainer, discard the cooked ingredients in the strainer and chill the marinade. Place fish steaks or fillets in a baking dish and spoon some marinade over them, coating all sides. Marinate in the refrigerator for 1 hour. Pour off marinade into a small pan and heat to boiling. Grill the fish over hot coals, basting with a teaspoon of the marinade on each side. Remove fish when internal temperature reaches 155F or the fish is just flaky and the translucent color is gone.
