For the sesame balls, mix the flour, baking powder, sugar and mashed potato powder in a bowl. Gradually add the water until it forms a dough. Form balls from the red bean paste.
Form a long snake from the dough, cut small pieces from it, flatten it (as thin as possible) and wrap it around the bean paste balls.
Roll the finished sesame balls in sesame seeds and fry/fry them out in oil.
