Korean rice donuts made with sweet potato and rice flour! These sweet potato rice donuts are soft and chewy, and coated with cinnamon sugar. Makes 3 dozens
Combine flours, sugar, baking powder, and salt in a large bowl. Mash sweet potato and add to the flour mixture and rub together until the flours become fine crumbs.
Slowly add hot milk (1/4 cup of milk each time) to the mixture and mix together with a spoon first, then using hand bring the dough together to form a ball shape. The amount of milk depends on the moisture level of your potatoes. It should resemble the bread dough consistency.
Make them into 1-inch balls with the dough. Set aside and cover with a towel.
Heat oil in a wok or fryer over medium low temperature. Drop a few dough balls and start rolling with a metal utensil to brown them evenly, about 5 minutes. Make sure your oil is not too hot. About 145ºC is ideal temperature.
Transfer the donuts to a plate lined with paper towel to remove extra oil on the surface. Roll the donuts in cinnamon sugar and coat evenly. Serve warm or at room temperature.
