Mussels

Let me tell you about mussels, and why they ask for so little from you in the kitchen.

A mussel is a bivalve, closed tight by two muscles that hold the shells shut against the world. A live mussel clamps when you tap it. A dead one gapes, loose and wet, and it has no business in your pot. So before anything else, look at the shell: closed, or closing when you disturb it, that's a yes. Smell it too — clean, like sea air, not like a dock at low tide.

Some cooks say that once a mussel has cooked, it has passed the test. No. Cooking is not where you judge a mussel — the judging happens before, raw, with your fingers and your nose. Once it's in the pot, trust what's in front of you: the meat should look plump, not shrunken or dry, and smell of the sea, the broth clean, not sour. If a mussel looks wrong or smells off once cooked, leave it out of the dish.

That misconception leads cooks to skip the raw check entirely, trusting the pot to sort good from bad. It won't. Trust your hands before the heat, and your nose after it.
