Crab eaten within sight of the sea, with salt still in the air and sand still in your shoes, tastes better than almost anything you can cook at home. It is also one of the simplest luxury foods in Britain — if you let someone else do the difficult part. The trick is not to overcomplicate it. Choose a good crab, keep it properly cold, pick the meat with a bit of patience, and serve it with nothing more than lemon, brown bread and a crisp salad. That is the whole business, and it is worth doing well.

Why Seaside Crab Is Worth the Effort

Fresh crab is a seasonal treat along the British coast, and the flavour of a well-handled one is sweet, clean and faintly minerally — nothing like the pale, watery stuff that turns up in cheap sandwiches. Because the meat is cooked twice over (once in the pot, once by the heat of the plate), it does not need cooking again. That makes it the ideal holiday food: you can buy it in the morning, carry it back to a rented cottage or a caravan, and have it on the table by teatime with barely any heat involved.

Let the Fishmonger Do the Hard Work

If there is a fishmonger nearby — and along most coastal towns there is — ask them to cook and prepare the crab for you. This is not laziness; it is good sense. Handling a live crab is an unpleasant job for the inexperienced, and a fishmonger will do it in a fraction of the time with far less mess.

When you ask, be specific:

• Ask for it cooked — freshly boiled the same day if possible, then cooled and chilled.
• Ask which crab and why. A cock crab has larger claws and more sweet white meat; a hen crab has a wider shell and far more brown meat, which is richer and more intensely flavoured.
• Ask them to dress it — that means the shell cleaned, the gills, stomach sac and intestine removed, and the body meat and brown meat separated into tubs or packed back into the shell.
• Ask for the claws cracked if you do not have a nutcracker at home. A few firm taps with the back of a knife will do the rest.
• Have a cool box or a bag with ice packs in the car. Crab is delicate, and a warm boot on a July afternoon will undo all their good work.

Keep the Meat Properly Chilled

Once you are back, get the crab straight into the fridge. White meat and brown meat should be kept in separate covered containers — the brown meat is stronger in flavour and will tint the white if they sit together. Eat white meat within two days and brown meat within two, ideally sooner; neither improves with keeping.

A few practical points:

• Store it in the coldest part of the fridge, not the door.
• Cover it, but let it breathe rather than sealing it tightly in a hot container.
• If you are eating outside, keep the tubs on ice in a cool box and bring them out only when you sit down.
• Any crab left out for more than an hour or two on a warm day should be thrown away, not saved.

Picking the Meat Without Losing Your Patience

If you are picking it yourself, set up properly: a bowl for white meat, a bowl for brown, a plate for shell, a tea towel under everything to stop it sliding about, and a crab pick or a skewer. Work over the bowl so nothing is wasted.

Crack the claws with a nutcracker or the blunt back of a heavy knife — gentle pressure, turning as you go, so the shell splits rather than shatters. Dig out every last bit of white meat from the legs with the pick; it is fiddly but it is the best meat on the crab. Remove and discard the feathery grey gills, the small sac near the head and the dark vein running through the body. Keep the brown meat — it is the cook's reward, and it spreads beautifully on toast. Keep everything cold while you work, and put the bowls back in the fridge as soon as you finish.

Serving It Simply: Lemon, Brown Bread and a Light Salad

This is a dish that collapses under too much fuss. Dress the white meat with a squeeze of lemon, a drizzle of good olive oil, a little black pepper and perhaps a pinch of sea salt — no more. Leave the brown meat plain, or loosen it with a spoonful of mayonnaise and a dash of cayenne.

Alongside, serve:

• Brown bread and butter, sliced thickly, with proper salted butter. Soda bread or a decent granary loaf both work well.
• Lemon wedges, plenty of them, plus a small bowl of mayonnaise for anyone who wants it.
• A light salad — crisp leaves, cucumber, thin slices of spring onion and a sharp lemon or cider vinegar dressing.
• New potatoes if you want something more substantial, boiled and tossed with butter and parsley.

Eat it cold, outdoors if you can, with a dry white wine, a light ale or a glass of elderflower pressé. The whole point is that the crab is the centre of the plate and everything else is there to make it easy to eat.

Getting the Best From Every Bit

Do not discard the empty shell without a thought: a quick simmer in water with a bay leaf makes a surprisingly good base for a fish soup or a risotto the next day. Any leftover white meat is excellent folded through pasta with lemon zest and chilli, or piled onto toast with a little brown meat underneath. Buy from a fishmonger you trust, keep it cold, keep it simple, and seaside crab will reward you every time.
