What is Seaweed?

Seaweed is a general term used to describe various types of marine algae that grow in the ocean and brackish bodies of water.

Unlike plants, seaweeds don’t have roots, leaves, or flowers; instead, they have holdfasts to anchor themselves, and fronds that absorb nutrients directly from the water.

Seaweeds can range in size from microscopic phytoplankton to large macroscopic forms like kelp, which can grow up to 150 feet in length.

They are an essential component of marine ecosystems and are harvested for various uses, including food, cosmetics, and industrial applications like thickeners and stabilizers.

What Does Seaweed Taste Like?

Here are some types of seaweed and their general flavor profiles:

  1. Nori: Perhaps the most well-known type of seaweed due to its use in sushi rolls. It has a slightly sweet, salty, and umami flavor. When toasted, it becomes crispy and even more flavorful.
  2. Wakame: Commonly used in miso soup and seaweed salads, wakame has a subtle sweetness and is less salty than some other varieties. It has a slightly rubbery, but tender texture when rehydrated.
  3. Kombu: Known for its strong umami flavor, kombu is often used to make dashi, a Japanese soup stock. It is quite tough and is usually simmered to extract its flavor.
  4. Dulse: Often eaten dried as a snack or used as a seasoning, dulse has a salty and smoky flavor. When fried, some people say it even tastes a bit like bacon.
  5. Arame: This is a sweeter seaweed that is often used in salads or stir-fries. It has a mild, almost nutty flavor.
  6. Spirulina: Usually consumed as a powder, spirulina has a strong, slightly fishy taste and is generally mixed into smoothies or other foods to make its taste less noticeable.
  7. Irish Moss/Chondrus Crispus: This seaweed is often used as a thickener rather than for its flavor, but it has a subtle marine taste.
  8. Agar Agar: Like Irish Moss, agar agar is mostly used for its gelling properties and has a very mild flavor.
  9. Sea Lettuce: This green seaweed has a strong ocean flavor and is often used in salads or soups.

What Is The Texture Of Seaweed Like?

The texture of seaweed varies widely depending on the type and how it is prepared. Here’s a rundown of some common types of seaweed and their typical textures:

  • Nori – Crispy when toasted, but can become chewy when moistened (as in sushi rolls). When used fresh, it can be pliable and slightly chewy.
  • Wakame – Tender and slightly rubbery when rehydrated. It swells considerably when soaked, gaining a slippery, almost gel-like exterior.
  • Kombu – Tough and leathery in its dried form, it softens upon rehydration but retains a slightly chewy texture. Typically simmered to extract its flavors, making it more tender.
  • Dulse – When dried, it has a tough, leather-like texture. However, upon frying or rehydration, it becomes softer and more palatable. When fried, it can even be somewhat crispy.
  • Arame – When rehydrated, arame becomes soft and tender, with a texture somewhat resembling that of cooked mushrooms.
  • Spirulina – Typically consumed in powdered form, so its texture is generally determined by what it’s mixed with, such as a smoothie or juice.
  • Irish Moss (Chondrus Crispus) – Gelatinous when boiled and often used as a thickening agent, imparting a smooth, jelly-like texture to dishes.
  • Agar Agar Used primarily as a thickening and gelling agent, agar agar itself is usually not consumed for its texture, but it gives a firm, jelly-like texture to foods.
  • Sea Lettuce Thin and delicate, almost like tissue paper. When fresh, it can be crisp but becomes softer and more pliable when soaked.
