Final answer:
Flanken Ribs are beef cuts that can be sliced 0.5-inch thick for a regular cut or 1-inch thick for a thick cut, with variations in cooking method and taste.
Step-by-step explanation:
Flanken Ribs may be cut either 0.5-inch thick for REGULAR or 1-inch thick for THICK. These are cuts of beef that come from the rib section of the animal, specifically from the short ribs. The difference in thickness affects the cooking time and method as well as the texture and flavor of the meat when served. While thinner cuts may cook faster and are often used for grilling, thicker cuts are more suitable for slow cooking methods, providing a tender and flavorful result.
