Notes
You Asked, We Answered
Yes, but traditional dashi provides the signature umami flavor. You can also use kombu (kelp) and dried shiitake to make a vegetarian dashi.
Prepare the broth ahead, but add delicate vegetables and tofu just before serving to keep them fresh.
It’s best served fresh, as freezing may affect the texture of tofu and leafy greens.
This soup pairs beautifully with sushi, rice, grilled fish, or a light Japanese meal.
