Abstract: A modular cooking appliance for cooking a variety of foods has interchangeable tops and a base to receive the tops. The base has a burner that is fed from a fuel supply and controlled by a valve. The interchangeable tops mate to an open top. One of the interchangeable tops is a grill grate that fits in the open top. Another interchangeable top is a griddle with a flat cooking surface. The griddle mates to the open top and is kept spaced from the base to allow exhaust gases to escape. Another interchangeable top is a pizza oven with a stone portion and a dome portion. The stone portion directs exhaust gases from the burner into the dome portion.
