The Cook-o-matic 100 (more commonly referred to as the Lumbridge Castle Range or simply the Cook's range) is a cooking range that can be used by any player who has completed the Cook's Assistant quest. It is located on the ground floor[?] of the Lumbridge Castle, in the kitchen close to the staircase leading to the 1st floor of the castle. Many players use this range due to the fact that it reduces the chance of burning food.

For details on how much more effective this range can make a player's Cooking abilities, consult the cooking stop-burn table.
