The strong cooking urn (full) is an item made by filling a Strong cooking urn while cooking food. It can be teleported to Ernie by clicking it, giving 1050 Cooking experience. You can only have up to 10 full urns at one time. You must teleport them away before making more. A full urn can also be given to Ernie manually by using the item on him, or through a chat option while having a full urn in the inventory. Full urns can also be teleported automatically by toggling the "Auto teleport current skilling urn when full" option on under skilling options in miscellaneous gameplay settings.
