In a bowl, mix the glutinous rice flour with the silken tofu and sugar using Japanese chopsticks.
When small pieces form, mix the dough with your hands for a good 5 minutes. You will obtain a fluid and compact paste.
Make dough pieces, and then cut them to the same size. For this version I used 12g per 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 ahead of time. Prepare a bowl of cold water and a pot of 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.
Put them in cold water right away. Take your picks and gently skewer the mochi balls.
Heat a pan with oil and grill your mochi skewers on 2 sides.
