FFXIV – Anime Campaign AND PEGI (30s)
Before you begin, make sure that you have obtained Kachina in-game, either through the gacha or an event reward. Since Special Dishes can only be cooked by their respective owners, it is impossible to cook Kachina's Special Dish without owning her first.
When Kachina is in your character roster, you can cook Impeccably Organized using the Grainfruit Chips recipe on any stove with Kachina. It is made with the following ingredients:
Grainfruits are currently unavailable in-game, but you can obtain them from Natlan shops once version 5.0 is released. Meanwhile, cheese can be processed with milk, which can be purchased from general stores throughout Teyvat. If you use Kachina to cook Grainfruit Chips, there is a small chance that you will receive her special dish, Impeccably Organized.
