Outdoor griddles are used to perform the same task as their indoor counterparts. That task is to providing a flat, even cooking surface for several different food items. Pancakes, eggs, hamburgers and vegetables can all be cooked on the same plate. A main consideration when looking for an outdoor griddle is the overall width. The width will tell you how much space you need for the unit as well as how much cooking space there is. There is usually one burner per every 8 to 10 inches of griddle length. Each burner has a separate control so you can have different heat zones on the cooking surface. Outdoor griddles also have splash guards and a front side trough. The guards help prevent hot cooking oils form splashing onto surrounding furniture and guests. The chef will want to periodically scrape any oils or food residue into the trough to keep a clean griddle plate.
