Summarize the following:
When they've reached the fall-apart stage, take them out to get them ready for the next step. It's time for the final stage of cooking, which will ensure the ribs have a crispy exterior. If you treated your ribs with a rub, you can skip the barbecue sauce, but either way it adds a flavor burst to the ribs. Paint the top of the ribs with a liberal amount of barbecue sauce. You can whip up your own barbecue sauce by simmering the following ingredients together for 30 minutes beforehand: 1 1/2 cups ketchup 1/2 cup brown sugar 3 garlic cloves, minced 3 tablespoons apple cider vinegar 3 tablespoons Worcestershire sauce 1 teaspoon freshly ground black pepper 1/2 teaspoon salt Let them cook for an additional 10 minutes under the broiler, until the tops of the ribs turn brown and crispy. Place them on a plate to cool for a few moments. Barbecue beef ribs are excellent with potato salad, macaroni salad and extra barbecue sauce.
Remove the ribs from the oven or grill. Open the foil and add barbecue sauce. Place the ribs under the broiler. Remove the ribs from heat. Serve the ribs.
