A clipped form of the Japanese pronunciation of cook gives this Paramecia fruit its name, and the official English translations style it the Cook-Cook Fruit. Whatever Streusen touches, he can turn into food, and since the change is immediate and skips the kitchen entirely, he never lacks a way to feed himself or others. The same trick works defensively too, reshaping a hazardous item into something edible and easier to handle.
Nourishing though the results are, flavor is another matter, as Big Mom herself grumbled about the taste. That one flaw aside, only the ordinary Devil Fruit weaknesses limit the power. Sixty-three years back, Streusen was shown carving a log into meat and eating it straightaway, and his command of the fruit runs deep enough that an entire castle became food under his hand in a single moment. His signature move, Veränderung Gourmet, drives his sword into a target to convert it. He first put it to use on the collapsing Whole Cake Chateau, turning the structure into a real sponge cake crowned with whipped cream so that the debris would spare both the people riding it and the townsfolk of Sweet City underneath. The word Veränderung carries the German sense of change, and both the VIZ manga and the Funimation cuts rename the move Gourmetamorphosis.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
Streusen, longtime head cook of the Big Mom Pirates and once a member of the Rocks Pirates, is the sole eater. The fruit draws comparison to several others: like the Ato Ato no Mi it reshapes everyday objects to match the user's imagination, and it can bring forth foodstuffs much as the Kibi Kibi no Mi does, along with the Fude Fude no Mi.
The Kuku Kuku no Mi is a Paramecia type Devil Fruit that lets its user, Streusen, instantly turn any object into food without needing to cook it first.
Streusen, the head chef of the Big Mom Pirates and a former member of the Rocks Pirates, is the sole known eater of the Kuku Kuku no Mi.
The Kuku Kuku no Mi is officially translated as the Cook-Cook Fruit in English releases of One Piece.
Streusen's signature move, Veranderung Gourmet, involves stabbing a target with his sword to instantly transform it into food, as he did when he turned the collapsing Whole Cake Chateau into a sponge cake to protect the people below.
No, despite being nutritious, food created by the Kuku Kuku no Mi reportedly tastes poor, a flaw even Big Mom herself complained about.
