Roasting is a cooking method that uses dry heat, whether an open flame, oven, or other heat source. Roasting can enhance flavor through caramelization and Maillard browning on the surface of the food. Roasting uses indirect, diffused heat (as in an oven), and is suitable for slower cooking of meat in a larger, whole piece. Meats and most root and bulb vegetables can be roasted. Any piece of meat, especially red meat, that has been cooked in this fashion is called a roast. In addition, large uncooked cuts of meat are referred to as roasts. A roast joint of meat can take one, two, even three hours to cook – the resulting meat is tender. Also, meats and vegetables prepared in this way are described as “roasted”, e.g., roasted chicken or roasted squash.
