Prepare the Mochi Dough: In a bowl, mix the glutinous rice flour, cornstarch, granulated sugar, and milk until smooth. Strain the mixture to achieve a finer texture.

Prepare for Steaming: Cover the bowl with plastic wrap to prevent water droplets from getting in, and poke a few small holes in the wrap with a toothpick to allow steam to escape.

Steam: Place the covered mixture in a steamer and steam over medium-high heat for 25 minutes.

While steaming the mochi dough, prepare the dragon fruit by slicing it into cubes and making the juice.

Finish the Dough: Once steamed, add 5g of corn oil and 10g of dragon fruit juice to the dough. After it cools down, put on gloves and knead the dough for about 5 minutes, stretching and pulling until it becomes elastic.

Assemble the Mochi: Divide the dough into 50g portions. Flatten each portion, place a tablespoon of dragon fruit (or other fruit) in the center, and wrap the dough around it. Seal the edges and shape it into a ball.

Coat: Roll the mochi in coconut flakes before serving.
