Should you cover beef with foil when roasting?

How does meat change when it is cooked?

When heat from your stove, oven or grill is applied to white meat, the proteins within the muscle begin to break down in a process called denaturation. Further heating causes the denatured proteins to recombine, turning opaque and white in color, akin to when you fry an egg and the whites become white.

How does slow cooking make meat tender?

The moist heat they provide softens the connective tissue that binds the muscle fibers in the meat, helping it to fall apart more easily. And when the heat is kept low, as it is in slow cooking, the proteins in the muscle are less likely to overcook, so the meat stays moist as well as tender.
