Oni Manju ( Demon buns ) on a plate made by my daughter

I made Oni Manju, a snack that allows you to simply enjoy the deliciousness of sweet potatoes. The ingredients are simple and no oil is used.Since the sizes of the sweet potatoes vary, I gave the sweet potatoes as 100 and the other ingredients as percentages so that they can be calculated.
Oni manju ( Demon buns )" was made from sweet potatoes and flour, which were relatively easily available during the food shortages of the war and the postwar period, and became popular as a staple food in place of rice. The name "Oni manju" is said to have come about because the cubes of sweet potatoes cut into cubes look like the horns of an ogre or a metal rod.

235g sweet potatoes, net
