Questions
4 questionsCan I use fresh seaweed instead of dried seaweed?
Yes, fresh seaweed can be used, but you'll need about 3-4 times more volume since dried seaweed expands significantly when rehydrated. Fresh seaweed also has a milder flavor.
What's the difference between nori, kombu, and wakame?
Nori is thin and crispy, good for wrapping and garnishing. Kombu is thick and tough, best for making stocks and broths. Wakame is soft and delicate, ideal for salads and soups.
Is seaweed high in sodium?
Yes, seaweed is naturally high in sodium, but it also contains beneficial minerals like iodine, calcium, and iron. Use it as a natural salt substitute in cooking.
Can I substitute seaweed in sushi?
For sushi, nori sheets are the best substitute as they provide the right texture and mild flavor. Other seaweeds would be too strong or have the wrong texture for sushi rolls.
