How long does a parboil take?

This depends upon what you are cooking. If you are cooking a Boston butt roast, it may take 30 minutes. If you are cooking baby back ribs, it may take 10-15 minutes. The purpose of the parboil is to get the meat cooked through the center, thoroughly. That is very important with pork. Once the meat is cooked, not past the point of being done, it is usually put on a barbecue grill. There, the sauce is cooked onto and into the meat. Once the sauce is cooked on, the meat is removed from the grill and served fresh, hot, and everything is safely cooked.
