According to USDA, ribs are done when they are 145Â°F internal temp, but they may still be tough. If you take them up to 180Â°F, drop the oven temp to about 180Â°F and hold them at this temp for about 30 minutes, the collagens and fats melt some more at this temp and make the meat more tender and juicy.eat can cause this shrinkage. Put ribs on a hot grill and they will shrink within an hour, but they won't be done. On the other hand, if you keep the temp under 250Â°F, by the time the meat pulls back, it is overcooked. The peek-a-boo test.
At this rate the ribs should be cooked through and tender after 4 hours. Go longer if you can. The longer you smoke at a low temperature the more tender and flavorful the ribs will be. Remember that you need to hit an internal temperature of 165oF before they can be served.s with all traditional Barbecue, pork ribs should be cooked low and slow with a good dose of smoke. This process will require a smoker of some kind, although you can do it with a kettle charcoal grill. You will need a 200 degree temperature, smoke, and patience.
