Step 1

Preheat oven to 300 degree F (150 degrees C).

Step 2

Cut each full rack of ribs in half, so that you have 4 half racks. Sprinkle salt and pepper (more pepper than salt), and 1 tablespoon chile pepper over meat. Wrap each half rack in aluminum foil. Bake for 2 1/2 hours.

Step 3

Meanwhile, heat oil in a medium saucepan over medium heat. Cook and stir the onions in oil for 5 minutes. Stir in water, tomato paste, vinegar, brown sugar, honey, and Worcestershire sauce. Season with 2 teaspoons salt, 1/4 teaspoon black pepper, liquid smoke, whiskey, garlic powder, paprika, onion powder, dark molasses, and 1/2 tablespoon ground chile pepper. Bring mixture to a boil, then reduce heat. Simmer for 1 1/4 hours, uncovered, or until sauce thickens. Remove from heat, and set sauce aside.

Step 4

Preheat an outdoor grill for high heat.

Step 5

Remove the ribs from the oven, and let stand 10 minutes. Remove the racks from the foil, and place on the grill. Grill the ribs for 3 to 4 minutes on each side. Brush sauce on the ribs while they're grilling, just before you serve them (adding it too early will burn it).
