In English butchery, the thick rib is a primal cut situated between the shoulder and the middle rib, just below the chuck and blade, and above the thin rib.
This section is derived from the upper front portion of the cow, where the muscle is used more frequently, resulting in meat that is flavorful yet contains a fair amount of connective tissue. Given its structure and texture, thick rib lends itself well to slower cooking methods.
When braised, stewed, or slow-roasted, the connective tissues within the meat break down, leading to a tender, succulent, and flavorful result. The collagen in these tissues melts into gelatin, enriching gravies and sauces with a silky, rich mouthfeel.
