There are two varieties of ribs you see on the market. Some were cut from the back (loin), and others from the sternum. For long-term cooking, it is better to use the second option. The fact is that the ribs from the brisket have much-needed veins that prevent the meat from drying out. In addition, the bones in this case will be flat. The only disadvantage of such ribs is that the meat is tough, so they need to be cooked longer.
