Cooking by dry heat in an oven is a method of preparing food that involves heating the food in an enclosed space, such as an oven. This method includes four different techniques: baking, ROASTING, broiling, and ROASTING. Baking is the process of cooking food in an oven with dry heat, usually at a low temperature. ROASTING is the process of cooking food in an oven with dry heat, usually at a higher temperature. Broiling is the process of cooking food directly under a heat source, such as a broiler. ROASTING is the process of cooking food in an oven with dry heat, usually at a high temperature for a longer period of time.
