Deep-Fried Sweet Potato Balls

• Sweet potato
• Sugar
• Wheat flour or glutinous rice flour
• Peanut butter
• Sesame seeds

Boil sweet potatoes until soft (preferably with a crushed chunk of ginger). Mash flesh, season with sugar. Add enough flour to make a stiff dough. Pinch off a bit of dough; form into a flat circle, place a dab of peanut butter in the center, pull edges up, and seal into a small ball. Roll in sesame seeds; deep-fry until golden.
