Reheats is a term used to describe the process of warming up food that has already been cooked. It involves heating the food to a temperature that is hot enough to make it safe to eat, but not so hot that it burns or overcooks. Reheating can be done in a variety of ways, such as in the oven, on the stovetop, or in the microwave. The term WARMS is often used interchangeably with REHEATS, as they both refer to the same process.
