    Introduction to Oyaki

    Oyaki is a Japanese dumpling stuffed with seasoned vegetables, fruits, and even anko bean paste. It is a local dish of Nagano prefecture and locals wrapped different ingredients in wheat flour and buckwheat flour and baked. It is soul food that locals from Nagano prefecture ate for a long time and it is within their culture. Nagano prefecture is one of Japan’s true food bowls. It is a region of dramatic mountains and bountiful farmlands and they produce some of Japan’s best fruit, vegetables, meat, and rice. That’s why the prefecture’s specialty is kind of related to it. Now,  I will guide you through one of their specialty – Oyaki. 


    Oyaki (おやき)

    Oyaki in the past are often grilled or steamed, depending on local and personal tastes. So the name given to it relates to that. The “yaki (やき)” of the name oyaki (おやき) means “to grill,” since they were originally simply grilled on an open hearth. 

    What is Oyaki?

    Oyaki (おやき)

    Oyaki (おやき) is a traditional Japanese food from Nagano made by dissolving wheat flour, buckwheat flour, etc. in water then kneading it. Locals usually wrap it with bean paste, vegetables, etc. and thinly spread the dough, and bake it. Oyaki is usually made at home to enjoy as either a meal or a snack. Ingredients and preparations may differ widely, but whatever its form, the flavors of the humble oyaki are straightforward, best characterized by fresh local pickles, eggplant, mushroom, pumpkin, and other local produce. This food is handed down to each household as a substitute for rice in the winter. In addition, they made it as an offering in front of Buddha on August 14 every year in Obon.

    History of Oyaki

    Oyaki (おやき)

    Oyaki was and is comfort food. Traditionally families would sit around an open griddle and eat together on a cold snowy night. It is a specialty of the Nagano region, and Nozawa Onsen is close by. You can even go and see the snow monkeys of Japan which are also close by too just as an aside. Nagano Prefecture’s steep mountains and cold climate made rice cultivation difficult and produced poor yields in pre-industrial Japan. Farmers in Nagano turned to buckwheat or soba instead. This flour was then mixed with water and filled with local wild vegetables and often seasoned with soy sauce and salt and hence we get oyaki, steamed dumplings, or steamed buns if you will.

    How to make Oyaki?

    Oyaki dough procedure

    Making dough

    Put salt, cake flour and strong flour in a bowl and mix well. While adding boiling water, mix with chopsticks until it becomes a lump to some extent. When the whole thing is mixed, put it together by hand.

    Cutting the dough into parts

    When the dough becomes smooth, let it sit for 30 minutes. Cut into 6 equal parts in a stick shape. Dust it and spread it to a diameter of about 10 cm.

    Bean paste procedure (Nozawana)

    Preparing tofu

    Drain the fried tofu and cut it into diced pieces.

    Frying pork and other ingredients

    Heat sesame oil in a frying pan, add minced pork and pickled Nozawana and fry. After lightly frying, add fried tofu and all seasonings and fry to remove the juice.

    Bean paste procedure (pumpkin)

    Preparing and removing pumpkin seeds

    Remove the pumpkin seeds and cut them into bite-sized pieces.

    Seasoning and frying pumpkin

    Heat the vegetable oil in a pan, add the pumpkin from 1 and fry to blend. Add water and seasonings, bring to a boil, reduce to medium heat, cover, and simmer. Boil it so that it doesn’t burn until the juice is gone.

    Crush the pumpkin

    Roughly crush them and let them cool.

    Bean paste procedure (dried daikon radish)

    Soaking dried daikon

    Soak the dried daikon in water and put it back. After returning it, wash it well with running water and squeeze it well.

    Julienne carrots

    Peel the carrots and cut them into julienne, and for the fried tofu, drain the oil and cut into thin strips.

    Frying all ingredients

    Heat sesame oil in a pan, add 1 dried daikon radish, and fry, and when the oil is heated, add more carrots and fry.

    Adding other seasonings

    Add the fried tofu, soup stock, and other seasonings cut into half and mix. When it boils, cover it with a lid and simmer over low heat for about 20 minutes.

    Wrapping-baking procedure

    Shaping the oyaki

    Roll each oyaki ingredient into a shape that is easy to wrap. Lift the dough in the middle so that the surroundings are deflated, and close the side.

    Frying the oyaki

    Arrange the oyaki in a frying pan heated on low heat. Turn over the dough in order from the one with the burnt texture on high heat.

    Steam over medium heat and serve

    Add 100 ml of water to the frying pan, cover, and steam over medium heat for 7 minutes. Then, serve it.
