What you'll need
- Japanese yam (nagaimo) — 200g
- Green onion (naganegi) — 1/3 stalk
- Seasoned seaweed (ajitsuke nori) — 5 sheets
- Chopped green onion — a pinch
- White sesame seeds — to taste
- Mirin — 1 tbsp
- Soy sauce — 1 tbsp
- Yuzu kosho — 1 tsp
- Chicken bouillon powder — 1/2 tsp
How to make it
Finely chop 1/3 stalk of green onion. Peel 200g of Japanese yam and cut it into thin sticks.
In a bowl, combine the Japanese yam and chopped green onion. Add 1 tbsp mirin, 1 tbsp soy sauce, 1 tsp yuzu kosho, white sesame seeds to taste, and 1/2 tsp chicken bouillon powder. Mix well until the yam becomes slightly sticky.
Tear 5 sheets of seasoned seaweed into small pieces and add them to the bowl. Continue mixing until everything is evenly combined and the mixture becomes more cohesive. Finish by adding a pinch of chopped green onion and gently tossing. Serve and enjoy!
Tips
- Mixing the Japanese yam thoroughly with the seasonings helps release its natural stickiness, allowing the flavors to coat every bite.
- Adjust the amount of yuzu kosho to your taste. Adding a little extra gives the dish a bolder, more sake-friendly flavor.
- Don't be shy with the seasoned seaweed—it adds a rich umami depth that makes this dish even more addictive.
- For a slightly sweeter flavor, you can substitute the soy sauce with mentsuyu (Japanese noodle soup base).
