Seaweeds and human nutrition

Edible marine algae: Nearly all seaweeds are edible. Kelp and konbu—not at all tough. Giant kelp. Laver—the delicate red alga. Nori—a sought-after Porphyra product. Wakame—neither too tough nor too delicate. Winged kelp—almost as good as wakame. Bladder wrack—abundant everywhere. Sea palm—a rare delicacy. Arame—totally mild and sweet. Hijiki—a bit special and a little poisonous. Dulse—the robust red alga. Edible green algae. Agar—completely without taste. Spirulina—edible blue-green microalgae that pack a punch.

The taste of seaweeds: Taste and texture. Seaweeds and umami. Smoke and sulphur.

Seaweeds as saltIf you have no salt, you have nothing. Seaweed ash salt and smoked salt.
