Nori is the traditional Japanese ingredient created out of processed seaweed, more specifically the red algae Porphyra. The production starts with rinsing, draining, and slicing seaweed, which is later pressed and dried to create the rectangular sheets that are thin, flat, and black in color.


Through history, nori was mostly produced out of wild seaweed and was collected at its natural locations. The cultivation started in the 17th century, during the Edo period, when the growth in population increased the demand for nori. Today, it is commercially produced in a specially designed system of nets, where it is cultivated, then processed.

Wakame is a type of edible brown seaweed, reported to have numerous health benefits. Like other forms of seaweed, it usually comes in dry form and needs to be rehydrated before use. Its flavor is neutral, lightly briny, and slightly sweet.


In its dry form, the color of wakame is dark green, but when rehydrated, it turns into a bright, glossy, and vibrant green color. In Japan, it has been consumed for thousands of years, and some archaeological evidence shows proof of its consummation dating back to 3000 BC.

One of the most commonly utilized seaweeds in Oriental cuisine, kombu or konbu has long been a dietary staple in Japan, and refers to a type of brown seaweed, namely kelp of the Saccharina japonica species that is native to Japan but also extensively cultivated in China and Korea where it's known as haidai and dashima, respectively.


Apart from the great nutritional and healing values, kombu is also used for its flavor-enhancing properties: it is an invaluable natural source of glutamic acid whose powdery crystals emerge to the surface of the dried seaweed and easily dissolve in water, giving any food cooked with kombu its rich, umami flavor.

Hijiki is a type of brown or dull green seaweed growing on the coastlines of Japan, China, and Korea. Over time, it has become a staple seaweed used in numerous dishes due to its versatility. It dries quickly, yet maintains most of its nutrient content such as high amounts of dietary fiber, calcium, iron, magnesium, and vitamin K.


Hijiki is often used in stir-fries, soups, and fish dishes. It is believed that hijiki has been consumed since the Yayoi era, and it first appeared in print during the early Heian period in a publication called Tales of Ise.

Indigenous to Fiji, nama is a type of edible seaweed mainly harvested in pristine, shallow waters. Because of its unique shape, formed of tiny, crunchy spheres, it is also known as sea grapes. In Fiji, it is commonly eaten raw, as a fresh vegetable or a garnish and is often combined with lemon juice, chili, and fermented coconut.


As it is considered a delicacy, it can be merely paired with coconut milk. Nama is also an important commercial produce, often sold at local markets.

Resembling a leafy red lettuce, dulse or palmaria palmata is an edible dried seaweed product from Northern Ireland. It can be consumed on its own as a snack, but it is sometimes also used as a unique pizza topping. When fresh and raw, it tastes like the ocean due to its minerality, but when fried, interestingly, it takes on some smoky and savory characteristics that make it taste similar to bacon!

Although it contains the word 'bread' in its name, it has absolutely nothing to do with it because this is a fine black seaweed (Laver) which is harvested on the Welsh shores. It is unique because it is the only seaweed that is just one cell thick.


It is washed and cooked with salt until soft and then minced to a pasty texture with a unique saline flavor. Laverbread is full of nutritious elements and very rich in protein and minerals. It looks like a purée and is usually eaten with shellfish or spread on toast, but since it's very versatile, it can be used in sushi, soups, salads, in quiches or even in meat dishes.

Mozuku is a term for the brown seaweed that is harvested in the Japanese waters, but predominatly around Okinawa. Most popular type is Okinawa mozuku (lat. Cladosiphon okamuranus), but there are also ito mozuku (lat. Nemacystus decipiens), ishi mozuku (lat. Sphaerotrichia divaricata) and futo mozuku (lat. Tinocladia crassa).


This seaweed is characterized by its slimy texture and stringy appearance, making it quite distinct from other types of edible seaweed like nori or wakame. Mozuku is highly prized for its nutritional benefits, including a high content of fucoidan, a type of sulfated polysaccharide known for its potential health benefits such as anti-inflammatory properties, immune system support, and possibly anticancer activities.

Karengo is a type of edible seaweed, more precisely red algae of the Porphyra genus, which is indigenous to New Zealand. It ranges from dark green to purple in color and has a firm texture and mild flavor.

The plain version is commonly eaten as a snack, while the flakes are mainly used as a food supplement. Recent research has shown that there are more than 35 different species of karengo in New Zealand, and most still do not have scientific names.
