In a bowl, mix the glutinous rice flour with the silken tofu and sugar (optional) using Japanese chopsticks.
When you see small pieces forming, mix the dough with your hands for 5 minutes. You will obtain a fluid and compact paste.
Make dough pieces, it is at this stage that you can add your seasoning powder like matcha for example.
Cut out dough pieces of the same size, personally I took 20g for each dumpling.
Make smooth, round balls. Tip: To make them perfect, place a piece of dough in your hands and rotate it into a ball. Keep your hands flat.
Soak your wooden or bamboo picks in water. Prepare a bowl of cold water and a pot with boiling hot water. Cook your noodle balls in the pan of water for 2 to 3 minutes. As soon as the mochi rise to the surface they are cooked.
Then place them immediately in cold water.
Take your picks and skewer the mochi balls. You can garnish them and enjoy them with tea afterwards!
