Considered a quintessential delicacy in the Channel Island of Guernsey, Guernsey ormers are a type of shellfish, a gastropod mollusk that's been traditionally collected on the island for centuries. This native shellfish (also known as European abalone) is reminiscent of a flattened Pacific abalone (sea snail) but smaller in size.
Its flesh is succulent and has a unique, mild, and slightly meat-like, but still distinctively molluscan flavor. A decline in ormer numbers has led to a strictly controlled harvesting of the island's delicacy, limiting the ormering season to only 24 days in a year between January and April, on full and new moon.
