Steak is beaten to break down the fibers a little, making the meat more tender. Nowadays, cattle are slaughtered while they are still young and tender so beating steaks is less necessary, but you can do so if you want to shorten their cooking time. Place the uncooked meat between two sheets of plastic wrap or grease-proof paper, then pound it firmly with a meat mallet, the flat of a heavy knife, or a rolling pin. A gentler technique for tenderizing steak is to marinate it for a few hours.
