Oita sakemanju — steamed bun leavened with fermented rice-koji yeast, filled with sweet red bean paste

A yeast starter made from steamed rice and rice koji leavens a wheat dough wrapped around sweet red bean paste and steamed — a sweet from Taketa and Bungo-Ono raised purely by koji fermentation, its starter once handed down within a family from batch to batch.

What it's made of

Sake-manju, from the Toyohi region spanning Taketa and Bungo-Ono, is a steamed bun leavened with rice-koji fermentation and filled with sweet azuki bean paste. The soft dough, with a faint tang from the koji and the sweetness of the filling, gives it a simple, homey flavor. Fillingless versions also exist and go by other local names, such as "shiira" or "bappo," depending on the area.

How it's made

Cooked rice is mixed with koji and left for about two days to form a yeast liquid. Wheat flour is sifted with a pinch of salt, mixed with the yeast liquid, and kneaded until it reaches the softness of an earlobe. Sweet bean paste is wrapped inside, the bun is set on a sarsaparilla leaf, and it is left to rest for several hours so fermentation can raise the dough before it is steamed. A portion of each batch of dough is dried and kept as a starter, reportedly used to help the next batch ferment.

Why it took this shape

In the Toyohi region, ringed by the Sobo-Katamuki mountains and the outer rim of Mount Aso, sake-manju is said to have been eaten at summer observances such as the Boys' Festival, Obon, and local festivals. Because it relies on fermenting rice koji, it is said to be easier to make in the warmer months. Since the quality of the starter is said to shape how the buns turn out, passing it down through generations was reportedly the custom in the past. Eaten warm off the steamer, it also warms the body in winter, which is said to be why it has been enjoyed year-round.
