Kabocha Pumpkin Meatballs with Rice Flour

Adjust the amount of rice flour to be added to the kabocha puree depending on the consistency of the dough. The filling can be made ahead of time and frozen, so it will be easy to wrap around with the dough. The sauce is mild and smooth that helps these meatballs go down the throat easily, particularly for the elderly.

Directions
For the dough
Remove the seeds and skin from the kabocha pumpkin. Cook in the microwave for 4 minutes. Mash with a back of a fork. Cool and mix with rice flour. Set aside.
For the filling
Heat the oil on a skillet over medium high heat and sauté the onions. Add the mushrooms and ground beef. When cooked thoroughly, add miso, sugar, soy sauce, mirin and sake. Simmer until most of the liquid has evaporated.
In a small bowl, combine potato starch and water, and add to the meat mixture. When it has thickened, set aside to cool. If preparing in advance, freeze the filling in 2-3 portions, tightly wrapped.
Boil the steamer.
Using a spoon, take a golf ball sized portion of the kabocha puree in hand. Flatten it and place a spoonful of the filling in the center. Seal tightly on the top and tuck in the seam. Form a smooth ball and place them on a heat-proof dish. Repeat. Cover with plastic wrap.
Steam the pumpkin meatballs for 15 minutes.
For the sauce
In a saucepan, combine water, dashi powder, soy sauce, and mirin. Bring to a boil. In a small bowl, combine potato starch with water. Add to the sauce. Simmer until the sauce thickens.
Plate the meatballs in individual bowls. Pour the sauce and garnish with green onions and kaiware radish sprouts (optional). Serve.
