Oyaki (Japanese Stuffed Dumplings)

Step 1

Gather all the ingredients.

Step 2

Using the fine mesh strainer, sift the flour into a large bowl. Combine hot water, oil, and kosher salt.

Step 3

Mix the dry ingredients and wet ingredients with chopsticks until you can pick up the dough with hands.

Step 4

Use the dough to pick up crumbs in the bowl.

Step 5

Knead on a lightly floured surface for about 3 minutes, until a smooth dough forms. In Japan, we say “knead until the texture is like your earlobe”.

Step 6

Form the dough into a ball, put it back in the bowl, cover with plastic wrap, and let it rest at room temperature for at least 30 minutes or longer. Letting the dough rest increases its elasticity making it easier to work with later, so please don't skip.

Step 7

While the dough rests, make the fillings. Remove the eggplant stem and cut it half vertically. Then slice into half circles. Soak in water for 5-10 minutes (Meanwhile, you can cut Kabocha). Drain well and set aside.

Step 8

Heat sesame oil in a large frying pan and sauté eggplant until it is coated with oil. Cover the lid and cook on low heat for 5 minutes.

Step 9

When tender, add sugar and combine well.

Step 10

Add miso and julienned shiso leaves, and mix well together. Transfer to a dish to let cool.

Step 11

Cut the kabocha into smaller wedges and remove the skin (See How To Cut a Kabocha Squash).

Step 12

Cut each wedge into thin slices and then cut into thin strips.

Step 13

Heat the oil in the frying pan and sauté the kabocha. When it’s coated with oil, add water and cook covered for 5 minutes on low heat.

Step 14

Add sugar and combine well.

Step 15

Add soy sauce and pinch of salt. Mix well together.

Step 16

Transfer to the dish to let cool.

Step 17

Roll out the rested dough into a rectangular or circle shape and divide it into 12 pieces.

Step 18

Make each dough into a ball then press down with your hand.

Step 19

Stretch the dough to 10 cm (4 inches) in diameter. The important trick is to keep the center thicker than the edges. Using your fingers, stretch the outer edges by rotating the dough. This way, when you pinch the dough to seal, the dough won’t be too thick/too much.

Step 20

Place about 1 Tbsp of the filling in the center of each piece of dough. Close the oyaki by bringing the dough up over the filling, pinching at the top to seal.

Step 21

I use the same pleating technique as my Nikuman recipe (see the video on how I close the dough and pinch).

Step 22

After pinching the dough, put the pinched-side down on a lightly floured surface and twist a few times. Then press the top of the oyaki a little bit into a slightly flat ball.

Step 23

Set a steamer ready, by placing a steamer basket on top of wok/pot filled with enough boiling water. If you don’t have a steamer, after cooking the oyaki in a frying pan, add ¼ cup water to the pan. Cover with a lid and steam it until the water evaporates.

Step 24

Heat the oil in a frying pan (12 inch) and cook oyaki, pinched-side down.

Step 25

Pan fry for 3-4 minutes each side, or until golden brown.

Step 26

Transfer the oyaki to a steamer basket and cover to cook on high heat for 15-20 minutes (depending on the size of the oyaki and filling – small one should take about 10 minutes). Make sure the lid is covered with the kitchen towel so condensation on the lid doesn’t fall onto the oyaki.

Step 27

When they are done steaming, transfer to a wire rack (I use a bamboo strainer) where the heat can escape from the bottom.

Step 28

Enjoy them immediately. As soon as they become warm, not hot, cover the leftovers with plastic wrap (I wrap individually). Don’t wait until completely cooled down. You can freeze to store for up to a month, and re-steam to enjoy later.
