6 pounds pork spareribs (about 3 whole racks)
2 tablespoons vegetable oil
2 medium onions, finely chopped
4 garlic cloves, minced
2 cups tomato puree
3/4 cup pure maple syrup
1/4 cup soy sauce
Crushed dried red pepper flakes
2 tablespoons apple cider vinegar
Position rack in center of oven; preheat to 400 degrees F. Sprinkle ribs with salt and pepper. Wrap each rib rack tightly in heavy-duty foil; set on rimmed baking sheet. Bake ribs 45 minutes. Cool slightly. Unwrap; drain juices. Cut into individual ribs.
Meanwhile, heat oil in heavy medium saucepan over medium heat. Add onion and saute until tender, about 10 minutes. Add garlic and saute 1 minute. Add tomato puree and next 3 ingredients. Bring to boil. Reduce heat to low and simmer until sauce thickens slightly, about 20 minutes. Stir in vinegar. Season sauce to taste with salt and pepper.
Line same baking sheet with foil. Dip ribs into sauce. Place ribs, meaty side up, on sheet. Roast 15 minutes. Dip into sauce again. Roast until meat is very tender, about 20 minutes.
