Suji-aonori is the most aromatic variety of green laver. Milled fine, a pinch carries clean marine umami and vivid green to oil, batter, or a finished plate.
Aonori covers several species of green seaweed, and they are not interchangeable. Suji-aonori is the one traditionally valued and graded for its aroma. Aosa and hitoegusa are sold under the same word and carry the same aroma compounds in smaller amounts.
Rising water temperatures put the traditional harvests under severe pressure, and the variety became difficult to source. It returned through land-based cultivation. Sea Vegetable, the producer, built the first system of its kind for this seaweed: mineral-rich underground seawater held at a stable temperature through the year and kept in constant motion, so the strands grow evenly under sunlight.
The strands are dried while they are still fresh. That is what keeps the off-notes down and leaves the aroma clean rather than fishy, and it is the part of the process the producer credits for the finished character of the powder.
Ayako, Umami Curator at The House of Umami, visited Sea Vegetable's cultivation site in Kochi, Japan — a land-based facility built at the edge of the sea. She watched the seaweed move through the system — seeded in small tanks, transferred to medium ones, then to tanks large enough to walk around. The strands floating on the surface were beautiful, and every tank was scrupulously clean. Growing on land what the sea and the rivers can no longer give is what she wanted to stand behind. Carrying it is her answer to that.
The aroma is volatile. Heat drives it off, so the powder goes in off-heat or over the plate. It disperses readily into butter, cream, aioli, and oil-based sauces.
