A Batta tin is used for making battas. It can be obtained in the Grand Tree by buying from the Gnome Restaurant food shop owned by Hudo, by searching the nearby cupboard to find one, or by looting it from the gnomes in the stronghold. This way takes much longer because it rarely drops, so it is not recommended. If you add 1 Gianne Dough into the tin and cook over the Gnome Cooker or any other range, you will make a Half baked batta. From here, you can make any of the battas in the Gnome cuisine, such as Worm Batta, toad batta, Cheese and Tomato Batta, Fruit Batta or a Vegetable Batta.
