After the dough has risen, gently punch out the air and divide it into 8 equal portions, about 45g each.
Shape each portion into a ball, cover with plastic wrap, and let them rest for 15 minutes.
Remove the mochi from the fridge, dust it with flour to prevent sticking, and divide it into 8 equal portions. Shape each portion into a ball.
Flatten each dough ball and place a mochi ball in the center. Seal the dough around the mochi, ensuring it is fully enclosed.
Place the filled dough balls in a container, cover with plastic wrap, and freeze for 30 minutes.
Meanwhile, take the crust dough out of the freezer, divide it into 8 equal portions (about 20g each), and roll them into balls. Flatten each ball.
Remove the dough balls from the freezer and carefully place the crust over each one, ensuring it covers the entire surface.
Roll each crust-covered dough ball in a bowl of sugar to coat.
Place the dough balls on a baking sheet and allow them to rise for 1 hour in a dry, draft-free environment. Do not turn on the oven or add hot water during this step.
Preheat the oven to 180ºC (356°F).
Once the dough has doubled in size, bake in the preheated oven for 10-12 minutes, or until the crust is golden brown and the dough is cooked through.
Allow the melon pan to cool slightly before serving. Enjoy your homemade hojicha mochi melon pan!
