Limu Kohu.

Reddish-pink, soft and feathery — perhaps the most highly prized Hawaiian limu.

Red algae

Limu kohu is a soft, feathery reddish-pink algae often considered the most highly prized of all Hawaiian limu, with a clean, sharp, almost iodine-like flavor.

It is the traditional finishing limu in poke and is so valued that gathering rights for the best beds were once held by specific families.

Kohu has shot to global fame for an unexpected reason: recent science has shown that adding even a tiny amount to cattle feed cuts methane emissions by over 80% — making it a leading candidate to reduce livestock-driven climate impact.
