Put water on a 2- quart saucepan about 2/3 full.
Combine sugar and toasted sesame seed balls in a bowl
In a separate bowl, combine sweet rice flour with water, mix until it sticks together and form a ball of dough. Knead lightly, it shouldn’t be dry nor too wet, if its sticky add more flour and a little more water if it’s too dry. Take about 2 tablespoons and roll it in between your hands to form a ball, indent a hole with your thumb and put a teaspoon of the filling in it, close the hole by pushing the dough to cover the filling completely. Repeat with the remaining dough.
Drop balls carefully in the boiling water and wait for it to float on top, once it does, it means it’s already cooked. Use a slotted spoon to transfer cooked dough balls in a plate or tray. Wait until it’s cool to the touch befor rolling it to the sesame seed-sugar mixture.
That’s it! Done. Munch away
