What is the piece of commercial kitchen equipment most often used?

The convection oven is often considered the most frequently used piece of commercial kitchen equipment because of its versatility and efficiency in cooking. It circulates hot air around the food, allowing for even cooking and browning, which is essential in a fast-paced restaurant environment. This method reduces cooking times, enhances temperature consistency, and can accommodate various types of food simultaneously.

In comparison, while range tops and range ovens have their specific uses in cooking, they are often complemented by other equipment rather than serving as primary tools for various cooking techniques. Dishwashers play a crucial role in maintaining sanitation and efficiency in the kitchen, but they are not directly involved in the cooking process. This distinction makes the convection oven a standout choice when considering equipment that is used frequently in commercial kitchens.
