The ideal temperature for cooking ribs depends on the method of cooking and the desired level of tenderness. For smoked baby back ribs, the internal temperature should be above 170°F (77°C) and kept there long enough to tenderize. Wrapping the ribs can help achieve this temperature faster, and they should be tender enough to eat when they reach 200°F (93°C) . For ribs cooked on the grill, the grill should be heated to 275°F, and the ribs should be cooked for four to five hours. The internal temperature of the ribs should be between 190°F and 200°F when finished. According to the USDA, pork ribs should be cooked to an internal temperature of 145°F for safety reasons, but this temperature will result in rubbery and tough meat. Pork ribs should be cooked to an internal temperature of 195°F to 203°F for tender, juicy ribs with broken-down collagen and fat. The temperature can vary from slab to slab, but most ribs are done between 195°F and 205°F. It is important to use a reliable instant-read thermometer to check the internal temperature of the ribs, and the thermometer should be inserted into the meaty part of the ribs, avoiding the bones.
