More and more, restaurants are using this method of cooking. You will need a vacuum seal system for this recipe and a Sous Vide System. Cooking time = the time the ribs will be in the controlled water bath of 138°F for 24-48 hours. In this recipe we "cooked" the ribs for 24 hours. The ingredient amounts are approximate, with the exception of the seasoning mix. Make as many ribs as you like. I fit 2 slabs, packed in several sealed bags, in the Sous Vide. Use your favorite rib rub or make a batch of recipe#390416, use your favorite BBQ sauce at grilling time.
