Cooking Fresh Mussels with Cider and Herbs

A supper that smells of the harbour

There is a particular kind of evening, usually in late spring or early autumn, when the light goes long and gold and the kitchen window is open, and the only thing that will do is a bowl of mussels. Nothing else. Not fish pie, not a plate of grilled mackerel, not the fancy thing you book a table for. Mussels are the dish that tastes most like living near the sea, and they are also, quietly, the fastest supper in the coastal repertoire.

This is the version I cook most often: mussels steamed open in dry cider with garlic, shallots and a fistful of parsley, then finished with a little cream so the broth turns glossy and worth chasing with bread. From a cold fridge to a full bowl in under twenty minutes. Scrubbing them is the only real work, and even that is pleasant if you have a radio on.

Buying mussels: what to look for

Good mussels tell you everything themselves. Live ones are closed, or close sharply when you tap them on the worktop. They should feel heavy for their size, which means they are full of seawater rather than dried out, and they should smell clean and briny, like a rockpool at low tide. If the bag smells sharp or ammoniacal, walk away.

Ask your fishmonger when they landed. Mussels keep in the fridge for a day, wrapped loosely in a damp cloth or a bowl with a tea towel over the top. Never seal them in a plastic bag and never leave them sitting in a puddle of tap water; fresh water kills them.

• Rope-grown mussels from sheltered estuaries are generally plumper and grit-free.
• Aim for roughly 500g per person for a main course, 250g as a starter.
• Mussels are at their best in the cooler months, though farmed ones are good all year.
• Shells with a small chip or a barnacle are fine. Cracked and leaking ones are not.

The cider and herb formula

This is a formula rather than a fixed recipe, and it scales easily. For four people you want about 2kg of mussels and a base built on butter, alliums, cider and herbs.

• 2kg live mussels, scrubbed and debearded
• 50g salted butter
• 2 banana shallots, finely chopped, or 1 small onion
• 3 or 4 garlic cloves, sliced thin rather than crushed
• 300ml dry cider, proper dry stuff, not sweet
• 100ml double cream
• A large handful of flat-leaf parsley, roughly chopped
• A few sprigs of thyme and a bay leaf
• Plenty of black pepper and only a pinch of salt, if that

The cider does the heavy lifting here. Dry cider brings acidity and a faint apple sweetness that flatters shellfish far better than white wine in my view, and it is usually cheaper. Thyme and bay keep it savoury; parsley goes in at the very end so it stays green and bright.

How to cook them: eight minutes, no more

Rinse the mussels under cold running water, scrubbing any grit or barnacles off the shells with the back of a knife. Pull off the little fibrous beard if there is one, tugging towards the hinge. Discard any that stay open and refuse to close when tapped.

In a large, heavy pan with a tight lid, melt the butter over a medium heat. Add the shallots and a pinch of salt and sweat them for four or five minutes until soft and translucent, not coloured. Add the garlic, thyme and bay and cook for another minute, just until the smell fills the room.

Pour in the cider and let it bubble hard for two minutes to burn off the raw edge. Tip in the mussels all at once, clamp on the lid, and shake the pan. Steam them for four to six minutes, shaking once or twice, until the shells have opened wide. Anything still shut after eight minutes should be thrown away, not prised open.

Now lift the mussels into warm bowls with a slotted spoon and leave the liquor in the pan. Add the cream and simmer for a minute or two until it thickens slightly, then stir through most of the parsley and taste. The broth is usually salty enough from the mussels themselves. Pour it over the bowls and scatter the rest of the parsley on top.

Serving, and what to do with the broth

Warm bowls matter, because mussels cool fast. Beyond that, you need bread, and lots of it, ideally a sourdough or a crusty white loaf torn rather than sliced so the edges soak properly. If you want to make it a fuller meal, a bowl of chips alongside is deeply unfashionable and completely excellent. A green salad with a sharp mustard dressing cuts through the cream.

When you have eaten the mussels, do not pour the remaining broth away. It is the best part. Tip it back into a jug, chill it, and use it the next day as the base for a fish stew, a risotto, or a sauce for a piece of grilled hake. It will keep for two days in the fridge.

Small variations worth knowing

Once you have the method, you can drift. Swap the cider for perry or a dry white wine. Add a chopped rasher of smoked bacon or a few slices of chorizo with the shallots and the whole thing turns smoky and richer. A teaspoon of Dijon stirred into the cream sharpens it. A pinch of saffron in the cider gives a warmer, southern feel. A little chopped dill instead of parsley makes it more Nordic; chervil makes it more delicate.

What stays constant is the timing, the lid, and the restraint. Mussels need heat and a few good partners, nothing more. Cook them on a Friday with a cold glass of the same cider in your hand, and you have the coast on a plate, without any fuss at all.
