On the plate

Crunchy sweet siphon, almost cartilaginous; the softer mantle is cooked separately.

Avoid: Cooking the siphon more than a minute: it turns rubbery and loses all its crunch.

It is the heaviest burrowing clam in the world and one of the longest-lived animals known: some pass a hundred and fifty years.
