First prepare the meatballs. Add 200 g ground chicken to a bowl along with ½ tbsp yellow miso paste (awase), 1/2 tsp Japanese soy sauce (koikuchi shoyu), ½ tsp grated ginger root and 1 clove grated garlic. Mix until the ingredients are well distributed (especially the miso, we don't want any lumps!).
In a small separate bowl, crack 1 egg and lightly whisk.
Add the egg and 2 tbsp cornstarch to the chicken mince, mix until you have a sticky mixture. Cover and refrigerate until it's time to cook. These can be prepared ahead of time.
Broth
Add 1000 ml dashi stock, 1 ½ tbsp Chinese-style chicken bouillon powder, 1 tbsp Japanese soy sauce (koikuchi shoyu), 1 tbsp mirin, 1 tsp grated ginger root, 2 cloves grated garlic, and 2 tbsp ground sesame seeds to the pot. Mix well and bring to a gentle boil over a medium heat.
Once boiling, add the meatballs by scooping the ground chicken mixture onto a spoon and using another spoon to scrape it directly into the broth (the mixture is too wet and sticky to roll into balls).
Once the mixture is used up and all the meatballs are in the broth, cover with a lid and cook for 3 minutes.
Other ingredients
Add 1 carrot and any root vegetables first as they take a bit longer than the other vegetables. Boil for a few minutes before adding the rest of your vegetables and 150 g firm tofu. Simmer with the lid on for 10 minutes.
Turn off the heat and mix in 2 tbsp yellow miso paste (awase) by scooping it onto a miso strainer and dipping it in the broth. Use chopsticks or a small whisk to break up the miso paste and gradually incorporate it into the rest of the broth.
Tip: If you don't have a miso strainer, pour a small amount of broth into a bowl and whisk to break up the miso before pouring it into the pot.
Mix well and serve. You can enjoy this dish with rice or savor the leftover soup with udon noodles.
Notes
If you have a portable stove, you can sit it on your table and continue to cook and more add ingredients until the broth is gone.
Note: While the nutritional information includes the full serving of broth, most people in Japan don't actually finish all the soup.
