Grooved griddle surfaces are a common plate modification for commercial applications. Typically done to allow a sufficiently hot griddle to create branding marks similar to what might be found on a charbroiler, but without the need to maintain two pieces of equipment for that purpose. The geometry of the grooves is typically unique for each manufacturer, and tapered from the back of the griddle plate towards the front to facilitate the drainage of grease and other fluids. Effective cleaning of a grooved griddle can be performed with a wire or palmetto bristle brush, and many manufacturers provide a custom scraper designed to fit the geometry of the groove pattern. Griddles can be partially or fully grooved according to the needs of the customer, though extra care needs to be exercised when applied to griddles with embedded thermostats where the web thickness between the thermostat slot and top-side groove could result in breakthrough of the plate material.
