With this fruit, the user has easy access to food to feed themselves and others just by transforming an object into it. The user does not even need to cook the food. The user can also turn an object into food in order to make it less dangerous or otherwise more useful, as shown when Streusen turned part of the Whole Cake Chateau into cake to cushion the people on it and the people under it when it fell.
However, while the food created by the user can provide nourishment, it apparently does not taste good, as Big Mom remarked, though that could just stem from Big Mom's very demanding palate. Other than that, the user is still affected by the standard Devil Fruit weakness.
Sixty-three years ago, Streusen was seen making meat out of a log by cutting it, and was immediately able to eat the meat. Streusen is very skilled in using his Devil Fruit, as he was able to transform an entire castle into food in an instant.
Veränderung Gourmet (変化食,Feaenderun Gurume?, meaning "Transformation Food"): Streusen stabs his sword into an object and transforms it into food. It was first used to change the collapsing Whole Cake Chateau into a real sponge cake with whipped cream in order to save the people on it and the residents of Sweet City below from the debris.Veränderung is German for "change". This technique is called Gourmetamorphosis in the VIZ manga.
Both this and the Ato Ato no Mi can transform everyday objects according to the user's imagination.
The fruit is similar to Kanjuro's unnamed Devil Fruit as both can create foodstuffs.
The fruit can be considered an inverse of Tama's unnamed Devil Fruit, in that it instead produces food from the user's own body rather than from their surrounding environment, the user is limited to only producing one kind of food (mochi) instead of many, and the food produced, while delicious, is not nourishing.
