Serves 4 to 6.

1 large yellow onion, sliced
4 jalape? peppers, sliced
4 cloves garlic, minced
4 (1 1/2 pound) racks baby back ribs
2 tablespoons Bone Dust BBQ Spice (see below)
3 limes, sliced
2 cans beer
2 cups gourmet BBQ sauce

Preheat oven to 325 degrees F.

In a bowl, combine onion, jalape? peppers, and garlic. Spread mixture in a roasting pan.

Using a sharp knife, score the membrane on the backside of the ribs in a diamond pattern. Rub with Bone Dust BBQ Spice, pressing seasoning into meat. Lay ribs meat side down on top of onion mixture. Lay three or four lime slices on the back of each rib. Pour in beer. Cover tightly with lid or foil.

Braise ribs for 2 to 2 1/2 hours or until tender. Let cool slightly. Remove ribs from pan and set aside.

Pour onion-beer mixture into a large saucepan and bring to a boil. Reduce liquid by half, stirring occasionally. Add BBQ sauce. Return to boil, then remove from heat. In a blender or food processor, pur? sauce until smooth.

Meanwhile, preheat grill to medium-high.

Grill ribs for 6 to 8 minutes per side, basting with sauce.

Cut between every third rib and serve.
