Prepare the Mochi Dough: In a bowl, mix 1 cup of glutinous rice flour and 1/4 cup of sugar. Gradually add 3/4 cup of water and stir until smooth. The mixture should be thick but runny. Steam the mixture for 20-30 minutes, stirring every 10 minutes, until the dough becomes smooth and glossy.
Make the Red Bean Filling: Scoop the sweet red bean paste into small balls, about the size of a walnut. Set aside on a plate.
Shape the Mochi: Once the dough is ready, let it cool slightly. Dust your hands with cornstarch or potato starch to prevent sticking. Divide the dough into small portions and flatten each one into a disk, about 3 inches wide.
Fill the Mochi: Place a ball of red bean paste in the center of each dough disk. Gently fold the dough over the filling and pinch the edges to seal the mochi.
Wrap with Cherry Blossom Leaves: Soak pickled cherry blossom leaves in water to remove excess salt. Wrap each mochi in a cherry blossom leaf, securing it around the dough.
Serve and Enjoy: Your cherry blossom mochi is ready to be enjoyed! Serve it fresh, or store it in an airtight container.
