Combine the sweet rice flour, powdered sugar, and peach mash in a medium bowl. Use your hands to knead it together. Add the water and knead until it forms a soft dough (Just a little bit more moist than the consistency of playdough - if it's too dry, add a tiny bit more water).

Divide the dough into 18-20 1-inch balls and flatten each into a 1½ - 2" disk.

Spread the sesame seeds out on a small plate and press both sides of each disk into the sesame seeds.

Heat a thin layer of vegetable oil in a medium skillet over medium heat.

Working in batches of 5-6, fry each disk for 2-3 minutes on each side, until lightly golden brown.

Transfer to a paper-towel to drain and repeat until you've fried all of the disks.

Let cool slightly and serve.
