1.8 kg baby back pork ribs
160 ml water
80 ml red wine vinegar
240 ml ketchup
240 ml water
120 ml cider vinegar
80 ml Worcestershire sauce
60 ml prepared mustard
60 g butter
120 g packed brown sugar
1 teaspoon hot pepper sauce
0.5 teaspoon salt
Step 1
Preheat the oven to 175 degrees C. Place the ribs in two 25x38-cm roasting pans. Mix water and red wine vinegar in a bowl, then pour the diluted vinegar over the ribs and cover with foil. Bake in the preheated oven for 45 minutes, basting the ribs with juices halfway through cooking.
Step 2
To make the BBQ sauce: Combine ketchup, water, vinegar, Worcestershire sauce, mustard, butter, brown sugar, hot pepper sauce, and salt in a medium saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 1 hour.
Step 3
Preheat the grill for medium heat.
Step 4
Lightly oil the preheated grill. Transfer the ribs from the oven to the grill, discarding the cooking liquid. Grill over medium heat for 15 minutes, turning the ribs once. Baste the ribs generously with BBQ sauce and grill for 8 minutes. Turn the ribs, baste again with BBQ sauce, and grill for 8 minutes.
