TO COOK RIBS: prepare grill for indirect cooking over medium-low heat (250°F). Spread ribs with ginger and garlic. Place ribs on rib rack or in foil pan. Cook on covered grill 2 hours.
SPREAD half the bottle of Sweet Chili evenly over ribs. Continue to grill for another hour until tender.
BASTE ribs with remaining Sweet Chili during last 15 minutes of cooking. If desired, grill ribs over direct heat at end of cooking to char slightly.
Tips: To ensure that ribs will be very tender, score membrane on underside of ribs with sharp knife. When the snow is knee-high deep, bake the ribs at 250°F for 3 to 4 hours or until very tender. Note: Indirect Grill Method - Set drip pan filled halfway with water under grilling rack. Arrange coals around drip pan. Place food on rack over drip pan. Cover grill. If using a gas grill, turn gas off under drip pan.
