The main RuneScape Wiki has an article on: Fruit batta
The Old School RuneScape Wiki also has an article on Fruit batta.

A fruit batta is a type of gnome food that can be made with the Cooking skill. It can also be purchased at the Gnome Restaurant.

Making battas requires at least level 25 cooking. To make a fruit batta, mould a batta from Gianne dough. Bake it, then add four equa leaves. Bake it again, then add diced orange, lime and pineapple. Finish with gnomespice.
