I almost always order something really similar to this any time we go out for Japanese food, but I figured there had to be a way to make it myself. Unfortunately this isn’t vegetarian (I occasionally eat fish products), but I’ve done some research and apparently you can make a substitute for bonito flakes using dried mushrooms and kombu kelp. I plan on trying that really soon and I’ll add the recipe here as soon as I do.
2 bundles (about 6 ounces) soba noodles
thinly sliced green onion
1 cup water
1/4 cup soy sauce
1/4 cup mirin
2 tbsp bonito flakes
To make the dipping sauce, boil the water, soy sauce, mirin, and bonito flakes together for about 5 minutes. Pour through a strainer and let cool completely.
Boil the noodles in a large pot of rapidly boiling water until tender (5-8 minutes). Drain and rinse with cold water. Pile some noodles on a plate and sprinkle with green onions and sesame seeds. Serve with a small bowl of dipping sauce on the side.
