Recipe FAQs

What does wakame taste like?

Wakame has a mild, slightly sweet flavor with a delicate oceanic taste. When rehydrated, it becomes tender and silky with a subtle briny quality that complements miso-based broths beautifully.

Can I make this soup ahead of time?

Yes, you can prepare the broth and tofu mixture ahead, but add the miso paste just before serving. Boiling miso can destroy its beneficial enzymes and alter the flavor profile.

Is wakame seaweed healthy?

Absolutely. Wakame is rich in iodine, calcium, magnesium, and vitamins. It's low in calories but packed with nutrients, making it an excellent addition to a balanced diet.

What can I substitute for dashi stock?

For vegetarian options, use kombu (kelp) and shiitake mushroom broth. You can also use high-quality vegetable stock, though the authentic Japanese flavor will be slightly different.

Why shouldn't I boil miso paste?

Boiling miso paste can kill its beneficial probiotics and make the flavor harsh or bitter. Always dissolve miso in a small amount of hot liquid first, then stir it into the soup off the heat.
