In a mixing bowl, combine glutinous rice flour with the appropriate starch if using mochiko. Whisk to eliminate lumps.

Pour half of the measured water into the flour mixture. Mix with a spatula, gradually adding the remaining water while kneading until a smooth, pliable dough forms. Stop adding water once the dough reaches a soft, earlobe-like texture.
03 -
Divide the dough into halves (or quarters/sixths if making a larger batch), roll each portion into a cylinder, then cut each cylinder into 10 equal pieces. Roll each piece into a ball and gently press the center to make a small indentation. Arrange balls on parchment paper to prevent sticking.

Bring a pot of water to a rolling boil. Gently add the dumplings, stirring softly with chopsticks to prevent sticking. Boil until the dumplings float, about 3 minutes, then continue boiling for 1 additional minute.
05 -
Transfer boiled dumplings to a bowl of ice-cold water using a mesh spoon. Let them cool for 5–10 minutes, then drain thoroughly.
06 -
Serve dumplings with dark brown sugar syrup and roasted soybean powder as desired. For leftover dumplings, freeze on a baking paper–lined tray for 1 hour, then store in a freezer bag and consume within 1 month. Thaw in a microwave (40–50 seconds at 600W) or in cold water before serving.
