Steamed Oatmeal Pork Buns (Nikuman)

Make eight small steamed Japanese pork buns with oats, a bread-machine dough, and a pork, shiitake and bamboo shoot filling.

Freshly steamed oatmeal pork buns

Our one-year-old liked foods with a filling wrapped inside, so we added oats to this nikuman dough. We used onion in the pork filling to give it a flavor reminiscent of Japanese convenience-store buns.

Ingredients

8 small buns

  • 100 g cake flour
  • 40 g bread flour
  • 10 g oats
  • 2 g dry yeast
  • 90 mL water
  • A pinch of salt
  • 70 g ground pork
  • 1 shiitake mushroom
  • 30 g bamboo shoots
  • 1/2 onion
  • 1/2 teaspoon chicken bouillon powder
  • 1 teaspoon sesame oil
  • A small splash of soy sauce
  • 1 teaspoon mirin
  • 1 tablespoon potato starch, optional for thickening

Instructions

  1. Mix the cake flour, bread flour, oats and salt.
  2. In our bread maker, we added water, the flour mixture and the yeast in that order and ran the dough cycle. Follow your machine’s directions for the order of ingredients.
  3. While the dough mixes, chop the vegetables and combine them with the ground pork and filling seasonings.
  4. Divide the dough into eight portions. Flatten each to about 10 cm across, spoon on the filling, and pinch the edges closed.
  5. Set each bun on a small square of parchment so it does not stick to the steamer.
  6. The original batch steamed over high heat for 20 to 25 minutes. Use a thermometer to check that the center of the ground pork filling reaches 71°C (160°F).
