Recipe Questions & Answers

What is wakame seaweed?

Wakame is a nutritious Japanese seaweed rich in iodine, calcium, and minerals. It has a delicate flavor and tender texture when rehydrated, making it perfect for soups and salads.

Can I make this vegan?

Yes, simply use kombu and shiitake mushroom dashi instead of traditional fish-based dashi stock. Most miso pastes are naturally vegan, but always check the label to be sure.

Why shouldn't I boil the miso?

Boiling miso paste destroys its beneficial probiotics and can make the flavor bitter. Always dissolve miso in a separate bowl with hot broth first, then stir it into the soup at the end.

What can I add for more substance?

Sliced mushrooms, diced carrots, baby spinach, or cooked noodles like udon make excellent additions. You can also add shredded chicken or shrimp if you prefer a non-vegetarian version.

How long does dried wakame last?

Properly stored in an airtight container in a cool, dry place, dried wakame can last up to a year or more. Keep it away from moisture and direct sunlight to maintain quality.

Can I use other types of seaweed?

While wakame is traditional, you can substitute with kombu (kelp) or nori sheets cut into strips. Note that different seaweeds have varying textures and rehydration times.
