Barbequed Pork Ribs recipe.

Ingredients
5 pounds pork spareribs, cut into serving size pieces
1/2 cup butter
1 medium onion, chopped
1 tablespoon minced garlic
1/2 cup distilled white vinegar
1 cup water
1 cup ketchup
1 cup hickory smoke flavored barbeque sauce
1 lemon, juiced
salt and pepper to taste

Directions
Place ribs in large skillet or roasting pan. Cover with lightly salted water, and bring to a boil. Reduce heat to low, and simmer for 1 hour, or until meat is tender, but not quite falling off the bone. Remove from heat, and drain.
Place the boiled ribs in a roasting pan, and cover with sauce. Cover, and refrigerate for at least 2 hours.
Melt butter in a saucepan over medium heat. Cook the onion and garlic in butter until the onion is tender; remove from heat. In a blender, combine 1 cup water, vinegar, ketchup, barbeque sauce, and lemon juice. Pour in the melted butter mixture, and puree for 1 minute. Pour into a saucepan, and season to taste with salt and pepper. Bring to a boil, then remove from heat.
Preheat grill for medium-high heat.
Brush grill grate with oil. Grill ribs for 10 to 20 minutes, or until well browned, basting with sauce and turning frequently.
