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 aroma. Much of what reaches the market as green laver powder is a different species with a flatter, brinier profile.
Rising water temperatures put the traditional harvests under severe pressure, and the variety became difficult to source. It returned through land-based cultivation — the first system of its kind, using mineral-rich underground seawater held at a stable temperature through the year and kept in constant motion so the strands grow evenly under sunlight.
Only part of each harvest is dried fresh enough to be graded for this powder. Dryness, aroma, mouthfeel, salinity, and umami are each assessed before anything is packed. Drying the strands while still fresh keeps the brine note low, which helps keep the aroma clean rather than fishy.
Ayako, Umami Curator at The House of Umami, visited one of the land-based cultivation sites, a 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 into fat readily — butter, cream, aioli, oil-based sauces — without clumping.
