Start with the right crab
British brown crab, Cancer pagurus, is the species you'll most commonly find sold whole and ready-cooked from fishmongers, harbour stalls, and good fish counters. It's a meaty, flavoursome creature — the claws alone can be substantial — and it divides neatly into two quite different products: the firm, sweet white meat and the deeply savoury, almost paté-like brown meat. Both are worth having. Neither should be wasted.
If you haven't already, it's worth reading our pieces on the British crab season and on Cromer crab, which give the broader picture of when and where these crabs are at their best. For now, assume you have a whole cooked crab in front of you and you'd like to get into it properly.
The tools worth having
You don't need specialist equipment, but a few things make the job cleaner. A sturdy crab pick — or even a thin skewer or teaspoon handle — is essential for extracting white meat from the body's narrow channels. For the claws, you need something heavy: a rolling pin or the flat back of a large, heavy knife does the job well. A chopping board that won't slide, a bowl for the meat, and an old cloth or tea towel to keep things tidy round out the setup.
Taking the crab apart
Begin by twisting off all the legs and claws. They come away cleanly if you grip firmly and rotate rather than simply pull. Set the claws aside — they'll need cracking separately. The smaller legs have less meat but are worth a squeeze or a pass with the rolling pin to push out what's there.
Next, turn the body shell upside down. You'll see a small triangular flap on the underside, called the apron. Prise this up and pull it away. Now push your thumbs firmly up through the gap where the apron was, applying even pressure until the central body section pops free from the outer shell. It takes a little confidence the first time.
Inside the shell you'll find the brown meat — scoop it out carefully with a spoon and keep it to one side. Discard the stomach sac, a small greyish pouch you'll find just behind the eyes; it's not pleasant to eat.
On the central body section, you'll see a ring of pale, feathery, finger-shaped gills running around the sides. These are the so-called dead man's fingers, and they are the one part of a brown crab that you should not eat. They're easy to spot — soft, greyish-white, and quite distinct from the rest of the crab's interior. Pull them off and discard them before you go any further.
With the gills removed, break the body section in half. Inside, a honeycomb of chambers holds the white meat. Work methodically with your pick, pushing into each cavity and pulling the meat free. It's fiddly but satisfying, and this body meat is often more tender than what comes from the claws.
For the claws, wrap each one in a tea towel and give it a firm, controlled crack with the rolling pin — one good strike across the widest part of the claw usually does it. Peel away the shell carefully, watching for splinters of bone-like cartilage, and ease out the white meat in the largest pieces you can manage.
Dressing and serving
Once you have both meats separated, the traditional approach is to return them to the cleaned main shell — brown meat to the back, white meat arranged along the sides. The shell makes a natural, rather elegant serving dish, and this presentation is what most people mean by a dressed crab.
Good bread — a proper sourdough or a crusty white loaf — and a bowl of mayonnaise are the classic accompaniments, and they need no improvement. The two meats eat quite differently: the white meat is light and clean, best appreciated with a little squeeze of lemon; the brown meat is rich and intensely flavoured, wonderful worked into the bread with a generous amount of mayonnaise. There's no rule about which to eat first.
A dressed crab is best eaten the same day it's prepared, and kept cold until you're ready to sit down. Freshness is everything here.
