Tips for Preparing Seaweed

Ways to consume seaweed.

It’s advisable to soak the seaweed before consuming it.All seaweed, regardless of the group it belongs to, should be soaked for at least 20 minutes so it grows up to seven times its size and volume.

If it’s overly salty or sandy, wash it with cold water.

Blue-green algae, when soaked, can be cut into strips in the same direction as its growth. Red algae can be chopped or cooked whole. Agar can be cut before or after being cooked.

Cooking Tips

  • Wakame, nori, chlorella, kelp, spirulina, and dulse can be eaten raw.
  • Kombu seaweed requires at least 45 minutes of soaking and then half an hour of cooking. The resulting broth can be used to make soups or sauces or to cook vegetables.
  • Hijiki seaweed is best during the winter months and has a very strong flavor. You can use this seaweed to make soups, stews, and puddings. You must soak it for 30 minutes and then cook it for the same amount of time. Reheating it isn’t recommended.
  • Although you can use wakame to prepare dozens of dishes, it’s the quintessential ingredient of miso soup. You need to soak wakame for 15 minutes and cook it for 10. You can also eat it raw in salads.
  • Nori doesn’t need to be soaked. You can toast it on a frying pan until it turns gold or green. Then, cut it into pieces with scissors and grind them by hand (when they’re warm). You can add nori to soups or cereals.
  • Kanten seaweed is mainly used in cold sauces, creams, puddings, salads, or to thicken soups and stews.
