2 to 3 lb. western-style pork ribs
1/2 c. ketchup
1/2 c. finely chopped onion
1/4 c. cider vinegar
1/4 c. Worcestershire sauce
1/4 c. mustard
1/2 c. dark Karo syrup
1/2 c. Kahlua liqueur

Place ribs in a single layer in baking pan. Add enough water to generously cover the bottom of the pan. Cover with foil and bake in low oven (250°F) for about 4 hours. Check occasionally and add water if necessary. Drain water and let ribs sit at room temperature until completely cooled. Break cooled ribs into large bite-size pieces, removing any fat or bones. Combine remaining ingredients in a saucepan. Gently boil for about 15 minutes or until desired thickness. Mix sauce with meat and gently heat. Can be served alone or on buns.
