Kombu, wakame seaweed, and nori are all typical seaweeds in Japan, and they are widely loved by Japanese people.

Let’s see what the differences are!

Kombu

Overview

Kombu is the common names for several seaweeds belonging to Brown algae Kelp family.
It’s made of one large leaf at the tip of the root and stem.


95% of domestic production is produced in Hokkaido, and the type called ma-kombu, rishiri-kombu, hidaka-kombu, etc are the famous one.

Kombu is mainly used to dry and take soup stock.

Taste and Texture

Because kombu is rich in glutamic acid which is one of umami component, it brings great taste to cooking even in small amounts.
Of course, there is also a unique ocean scent.

Dried kombu is extremely hard, so people often cut them into fine stripes or simmer when eating kombu itself. Even the cut kombu and simmered one are still a little hard, so you can enjoy the chewy texture.

How To Use

Ingredient for Dashi

Kombu is predominantly used as a soup stock material. You need 1% kombu to water weight, and soak it in water or stew slowly until just before boiling.

Kombu dashi matches so well with any cooking because it has a soft flavor. Japanese people like to use this amazing soup stock for making miso soup, simmered dish, noodle dish, etc.

Tsukudani (Kombu boiled in soy sauce)

Pickles

Japanese-style pickles are not always using vinegar, but often made with only shredded kombu and salt. The vegetables will be perfectly salty and get great umami taste from kombu.

Oden (Fishcake and vegetable stew)
