Fu-mochi zenzai, the only dish served at the sweet shop run by Momokichi, the protagonist of the popular novel "Kyoto Gion Momokichi An no Amakara-cho Series". In the eighth volume of the series, Hanbei fu appears as a special-order supplier of fu mochi. The author of the book, Yasuhiro Shigauchi, and Tsuyoshi Tamaki, president of Hanbei fu, a specialty store of fu and yuba established in Genroku 2, teamed up to recreate fu mochi zenzai, which is now served at Cafe Fufufu An.

This menu item is made with simple ingredients: Hokkaido azuki beans, sugar, salt, Kyoto red bean paste, and fu from Hanbeifu. Another key point is that instead of the traditional square-shaped fu, the round shape is used, which has a chewy texture that goes well with zenzai.
