Collection: Japanese seaweed

Japan is a country turned towards the sea, and it is felt on the plate! With fish, algae are at the heart of Japanese cuisine and bring great richness to dishes thanks to the many edible varieties that exist. They are found most of the time dried or toasted, in the form of leaves or strips. In addition to being very tasty, they are rich in antioxidants, vitamins and iodine and they promote cardiovascular health.

Learn more about seaweed

The main types of Japanese seaweed used in cooking are:

  • Nori: Used to wrap maki and onigiri.
  • Wakame: Often added to soups, particularly miso soup.
  • Kombu: A key ingredient in preparing dashi broth.
  • Hijiki: Black seaweed used in salads or as a side dish.
  • Arame: Another black seaweed, often used in simmered dishes.

Seaweed is rich in minerals such as calcium, magnesium, and iodine, which are essential for thyroid health. It also contains vitamins A, C, E, and K, as well as antioxidants that help protect cells from damage. In addition, seaweed is a good source of fiber and has anti-inflammatory properties.

Nori is a thin, dried seaweed, often used to wrap sushi and maki, while wakame is a thicker seaweed, often used in soups such as miso soup. Nori has a crispier texture and a slightly salty taste, whereas wakame is softer and has a mild marine flavor.

Kombu is primarily used to prepare dashi, a base broth for many Japanese soups. It can also be cut into thin strips and added to stews or used to make tsukudani, a type of sweet-and-savory condiment. To prepare dashi, kombu is generally infused in hot water and then removed before boiling.

Nori is the seaweed most commonly used to make makis. It is dried and pressed into thin sheets, ideal for wrapping the rice and other ingredients in makis and sushi. Nori is known for its crisp texture and slightly salty flavor.

To rehydrate dried seaweed, place it in a bowl of cold water for 5 to 10 minutes, until it regains its original texture. Some seaweed, such as kombu, can be added directly to a hot broth to rehydrate while infusing it with flavor. Once rehydrated, the seaweed should be drained before use.

Popular recipes featuring seaweed include:

  • Miso soup: Often prepared with wakame.
  • Wakame salad: Enhanced with sesame dressing.
  • Onigiri: Rice balls wrapped in nori.
  • Dashi: Broth made with kombu.
  • Hijiki no nimono: Simmered hijiki dish with carrots and tofu.

The main seaweed used for sushi is nori (Porphyra), a red seaweed that turns green or black after drying and roasting. Here are the different types of seaweed used in sushi cuisine

  • Nori (海苔): The essential seaweed for maki, temaki, and sometimes for wrapping onigiri. It is sold in dried and roasted sheets, with different grades (gold, silver, bronze).
  • Kombu (昆布): This seaweed is used to flavor shari (sushi rice) by infusing it into rice vinegar or dashi broth.
  • Wakame (わかめ): Although rarely used directly in sushi, it often accompanies sushi dishes in the form of seaweed salad.
  • Hijiki (ひじき): More often used in side dishes than in sushi, it can be added to certain fillings.
