Ribs are a grilling favorite and these have a double dose of spice. Tabasco is used in the rub and marinade to make these ribs extra spicy and fall-off-the-bone tender.
Cut each rib rack in half. Preheat oven to 300 degrees. Combine the rub ingredients in a small bowl and mix well. Rub the ribs on all sides with the spice mixture. Wrap each halved rack in aluminum foil and bake for 90 minutes. Let cool, remove from foil, and separate racks into individual ribs.
Combine the marinade ingredients in a large bowl. Add the ribs and toss to coat, or divide the sauce and ribs between 2 extra-large resealable plastic bags and coat ribs well. Refrigerate ribs, covered, for at least 2 hours or overnight, turning occasionally.
Heat grill to medium-low. Grill ribs, turning occasionally, until heated through and to desire doneness, about 15 minutes.
