On the plate

Briny, fleshy and long, with a sweet finish that shifts from bed to bed.

Avoid: Throwing away the first liquor: it is a restaurant reflex, and it is exactly where the sense of place lives.

It changes sex several times in its life, sometimes from one season to the next, depending on water temperature and available food.
