Why Mussels Belong on the Coastal Kitchen Table

There is no more honest supper for someone who lives near the sea. Mussels are cheap, abundant and quick — twenty minutes from a cold counter to a steaming pot — and they taste of the shoreline in a way that no fishmonger's fillet quite manages. Along the British coast, from the Menai Strait to the estuary beds of Devon and the rope-grown mussels of the Scottish lochs, they are one of the great bargains of the season. The only skill required is a bit of patience at the sink, and a willingness to throw away anything that looks doubtful.

This recipe is the sort we cook after a day on the water, when the wind has been cold and nobody wants to fuss. Dry cider, shallots, butter and a modest splash of double cream. It is rich but not heavy, and the cider does the work that white wine usually does, with a touch more orchard sweetness that suits mussels beautifully.

Buying Mussels: What to Look For

You want mussels that smell of the sea and nothing else. A fresh one has a clean, briny scent; if the bag smells sharp, ammonia-like or simply tired, walk away. Shells should be damp and mostly closed. The old saying about only eating mussels in a month with an "R" in it belongs to a time before refrigerated transport and cultivated beds — modern rope-grown and farmed mussels are available and safe all year, though many cooks still reckon they are at their sweetest from autumn through to early spring, before spawning thin the flesh.

A kilo in the shell will comfortably feed two people as a main course with bread, or four as a starter. Buy them as close to cooking as you can, and don't leave them sitting in the boot of the car while you finish the shopping.

Cleaning: The Step That Actually Matters

This is where most disappointing pots of mussels are lost. Tip them into the sink and run them under cold water. Working through them one at a time:

• Scrub the shells with a stiff brush or the back of a knife, knocking off sand, grit and the little barnacles that cling to the ridges.
• Pull off the beard — the wiry tuft that pokes out of the shell. Grip it firmly and tug towards the hinge, or scrape it away with a small knife. It should come cleanly.
• Discard anything cracked or broken, and any shell that feels unusually heavy, which can mean it is full of mud.
• Tap any open mussel sharply against the side of the sink. A live one will close. If it stays open after a few seconds, bin it — that is a dead mussel, and dead mussels are the ones that cause trouble.

Once cleaned, keep them in a bowl in the fridge with a damp tea towel over the top and cook them the same day. Never soak them in fresh water for hours; it kills them and washes away the very flavour you paid for.

Cider, Shallots and Cream: The Cooking

Use a pan big enough that the mussels can sit in a couple of layers rather than a solid block, and cook them in two batches if you have to. Overcrowding means uneven cooking and a pool of watery liquid at the bottom.

For one kilo of cleaned mussels you will need about 40g of butter, three banana shallots finely chopped, two garlic cloves sliced thin, 300ml of dry cider, and 100ml of double cream. A good handful of flat-leaf parsley, chopped, and plenty of black pepper. No salt — the mussels bring their own.

Melt the butter in the pan over a medium heat and soften the shallots for five or six minutes until translucent but not coloured. Add the garlic for the last minute. Pour in the cider and let it bubble hard for two or three minutes, so the alcohol cooks off and the liquid reduces slightly and concentrates.

Tip in the mussels, clamp on the lid, and give the pan a firm shake. Cook for four to five minutes, shaking once or twice, until the shells have swung open. Lift the lid and look: they should be wide open and plump.

Discard any that remain shut. No amount of extra cooking will open them safely, and no sauce is worth the risk. Take the pan off the heat, stir through the cream and most of the parsley, and grind over a generous amount of pepper. The residual heat is enough to warm the cream through without splitting it.

Serving the Pot

Take the whole pan to the table with a ladle for the broth and a bowl on the side for empty shells. Hunks of sourdough or a crusty white loaf are essential — the cider and cream liquor is the best part, and it wants mopping. If you are feeding a crowd, a tray of oven chips or a bowl of buttered new potatoes turns it into a proper dinner rather than a starter. A dry, lightly sparkling cider in the glass alongside works far better than you might expect, though a crisp dry white or even a light ale will do the job.

A Few Coastal Kitchen Notes

• Washing up afterwards is the price of a mussel supper. Rinse the shells before they dry out and the job takes minutes rather than an age.
• Leftovers should be shelled, kept with the liquor, and eaten within a day — folded through pasta or a fish pie it is a treat.
• If the broth tastes too thin, lift out the mussels, boil the liquid hard for a minute, then take it off the heat before adding the cream.
• Smoked bacon or a pinch of chilli flakes added with the shallots gives a fine variation when the weather turns properly grey.

Cook them simply, respect the tap test, and be generous with the bread. It is the sort of meal that reminds you why you chose to live within earshot of the tide.
