Grab a fork or knife and poke a bunch of holes into the sweet potato's skin. Toss it in a hot oven set to 200°C/400°F for anywhere from 45 to 60 minutes. Let it cool a bit, then remove the skin—it should peel right off.

Mash that baked sweet potato until smooth, using a fork. Slowly mix in the sticky rice flour with the sugar using a spatula. Once it's coming together, use your hands to knead it into a soft dough that doesn't crumble or stick.

Split the dough into 12 sections. Roll each piece in your hands to form perfect round balls.

Mix half a cup (120ml) of water with a spoonful of sticky rice flour. Dip one ball at a time into this wet mixture. After that, roll them in sesame seeds stacked in a bowl. Swirl the bowl a bit so they're well-covered, then lightly press the coating onto each ball. Repeat till all balls are done.

Heat your oil to 125°C/250°F. Lower the heat once hot, and carefully add the sesame balls—they'll fall to the bottom first but will eventually float up. Stir them occasionally so they cook evenly. When the orange dough peeks through the seeds, they're done. Let the oil cool back down to starting temp before the next batch.
