The strengths are editorial judgments on a scale within the family, not measurements. They can be compared across the seaweed and kelp varieties, not directly against another family.

Aonori is a green seaweed dried into flakes or fine threads and used as a sprinkle seasoning. The flavor is fresh, ocean-like and rich in umami, and unlike the sheet-form nori, aonori needs no cooking: it goes straight over the rice, the eggs, the popcorn or the potatoes just before serving.

Background

Facts

Form
dried flakes (flake) or fine threads (suji)
Use
sprinkled over finished food; classic on okonomiyaki, takoyaki and yakisoba
Flavor core
umami from glutamate, ocean notes, grassy freshness
Suji aonori
considered the most aromatic and finest of the aonori types
Cultivation
the wild harvest in the Shimanto River in Kochi, the classic suji-aonori region, fell to zero in 2020 when the water at the river mouth grew too warm; today the variety is farmed on land in clean underground seawater
Storage
airtight, dark and dry; moisture is the worst enemy
