Elegant tangyuan drizzled with fragrant osmanthus syrup are a refined dessert. A family treat with delicate floral sweetness and chewy texture.
Combine 1 cup glutinous rice flour with ¾ cup water in a bowl, mixing until a soft dough forms. Add more water, a tablespoon at a time, if needed for pliability.
Divide the dough into 12 equal pieces. Keep unused dough covered with a damp cloth to prevent drying.
Flatten each dough piece, place 1 teaspoon black sesame paste in the center, and pinch closed to seal. Roll gently into smooth balls.
Bring a pot of water to a gentle boil over medium heat. Add tangyuan and stir briefly to prevent sticking; simmer until they float plus 2 minutes, about 5–7 minutes total.
While tangyuan cook, simmer 1 cup water with 4 tbsp rock sugar over low heat until dissolved. Add 2 tbsp dried osmanthus and 2 tbsp honey; warm gently (do not boil) for 2 more minutes to maintain floral aroma.
Transfer cooked tangyuan to serving bowls and drizzle generously with the osmanthus syrup. Serve warm for the best chewy texture and aroma.
