Dressed crab is the British summer holiday classic that fell out of fashion in the 1990s and is currently undergoing a quiet revival. Cornish pubs serve it. Cornish butchers prepare it. London restaurants charge £24 for it. And every fishmonger from Falmouth to Whitstable still offers it on their counter for £14.
Made at home, dressed crab costs around £8-10 per person and takes 45 minutes to pick a single 1kg cock crab. The picking is the time-consuming part. The dressing (mixing, seasoning, presentation) takes 15 minutes. The result is one of the most satisfying lunches you can put on a table.
This recipe walks you through both stages: how to pick a whole cooked crab, and how to dress and present the meat properly in the cleaned shell.
Key Takeaways
- Buy whole cooked Cornish brown crab from a fishmonger, around 1kg per crab
- One crab serves 2 people as a starter, 1 as a main
- 60% white meat to 40% brown meat by volume is the proper ratio
- Don't mix white and brown meat together, present them separately
- Eat with brown bread and butter, never sourdough
The Ingredients
Serves 2 as a starter, or 1 generously as a main
For each crab:
- 1 whole cooked Cornish brown crab, around 1kg
- 1 hard-boiled egg, white and yolk separated, finely chopped
- 1 tbsp finely chopped flat-leaf parsley
- 2 tbsp fresh white breadcrumbs (from 1-day-old bread)
- 1 tbsp full-fat mayonnaise
- 1 tsp Dijon mustard
- 1/2 tsp Worcestershire sauce
- Juice of 1/2 lemon
- A pinch of cayenne pepper
- Sea salt and black pepper
For serving:
- Slices of buttered brown bread
- Lemon wedges
- A small bowl of vinegar dressing
- Watercress or rocket
The crab must be a Cornish or Devon brown crab (Cancer pagurus), not blue crab or king crab. Buy whole, cooked, the day of preparation. Look for a crab that feels heavy for its size (a sign of plenty of meat inside). Avoid female crabs (with rounder underbellies) during their breeding season (April-June) for sustainability.
The Method, Step by Step
Step 1: Position the Crab
Place the crab upside-down on a large board. The flat underside (apron) faces up, the rounded shell underneath.
Step 2: Remove the Apron
Twist off the small triangular flap (the apron) from the centre of the underside. Discard.
Step 3: Separate Body from Shell
Hold the crab firmly in one hand. With the other hand, pull the body section (the central part with the legs attached) away from the round outer shell.
The body lifts cleanly with a firm pull. The shell remains as a separate piece, like a bowl.
Step 4: Remove the Inedible Parts
Inside the body, you'll see grey feathery gills (called "dead man's fingers"). Pull them out and discard.
Inside the shell, you'll see a translucent jelly-like membrane and the brown meat (the soft, paste-like substance). Scoop the brown meat into a separate bowl. Discard any green or white intestinal matter.
Step 5: Pick the White Meat
The white meat lives in three places: the body cavity, the claws, and the legs.
For the body, break the body section in half. Use a small fork or seafood pick to extract the white meat from the small cavities between the cartilage. This is fiddly work, but each cavity contains a substantial chunk of sweet white meat.
For the claws, crack the shell with a heavy knife or claw cracker. Pull out the meat in one piece if possible.
For the legs, crack the shell joints and extract the meat with a thin pick.
You should end up with around 200-250g of white meat from a 1kg crab.
Step 6: Dress the Brown Meat
In a small bowl, mix the brown meat with the breadcrumbs, mayonnaise, mustard, Worcestershire sauce, half the lemon juice, the cayenne, salt, and a few cracks of pepper.
Mix until smooth and uniform. The brown meat should look like a dense, savoury paste.
Step 7: Dress the White Meat
In a separate bowl, gently mix the white meat with a tablespoon of mayonnaise, the rest of the lemon juice, a small pinch of salt, and a few cracks of pepper.
Don't overmix. Keep some chunks of white meat visible.
Step 8: Present in the Shell
Clean the empty crab shell with cold water and pat dry. Make sure all the grey feathery debris is gone.
Spoon the brown meat mixture into the centre of the shell, in a long stripe down the middle. Spoon the white meat on either side of the brown stripe, filling out the rest of the shell.
Decorate the top with the chopped egg yolk, egg white, and parsley in alternating stripes following the brown-white-brown pattern.
Plate with lemon wedges, brown bread and butter, and a small handful of watercress.
Tips for Getting It Right
Don't mix the brown and white meat together. The traditional presentation keeps them separate, side by side in the shell. They have different flavours and textures, and presenting them separately lets diners experience both.
Pick over a deep tray. Crab picking sends small fragments of shell flying. Work over a deep tray to catch everything. Inspect the meat carefully for shell fragments before dressing.
Cornish crab, not Asian alternatives. Brown crab (Cancer pagurus) is the British native species and the right choice for dressed crab. Avoid king crab (the legs are wrong), blue crab (too small), and snow crab (too sweet).
Don't overdress. The goal is to enhance the crab flavour, not mask it. Less mayonnaise, less lemon, less seasoning. Taste as you go and stop when the crab still tastes primarily of crab.
Brown bread, not sourdough. The classical British accompaniment to dressed crab is buttered brown bread, sliced thin. Sourdough is too tangy. White bloomer is too plain. Stoneground brown bread is the right choice.
Variations and Pairings
With caviar topping: Add a small spoon (5g) of Beleaev Oscietra caviar on top of the white meat just before serving. The combination of dressed crab and caviar is exceptional.
Cornish style: Add 1 tsp of finely grated horseradish to the brown meat mixture. The classic Cornish version has a slight kick.
With Marie Rose: Serve with a small bowl of Marie Rose sauce on the side. The classic 1970s British seaside addition.
Wine pairing: A flinty Chablis, a dry English Bacchus, or a properly chilled Sancerre. Avoid red wines and oaked Chardonnay.

Frequently Asked Questions
How do I tell if a crab is fresh?
A fresh whole cooked crab should feel heavy for its size, smell of clean sea (not fishy or sour), and have a bright orange-red shell. The legs should hold their shape rather than droop. If your crab smells off or feels light, return it to the fishmonger.
How long does dressed crab keep?
Up to 24 hours in the fridge, covered with cling film. Fresh crab meat deteriorates fast, so don't try to keep it longer. The breadcrumb in the brown meat dressing helps absorb excess moisture, but doesn't preserve the crab indefinitely.
Cock crab or hen crab?
Cock crabs (males) have larger claws and more white meat overall. Hen crabs (females) have wider bodies and more brown meat. For dressed crab, cock crabs are the traditional choice for the better white meat yield. Some prefer hen crabs in autumn for the richer brown meat.
What's the white feathery stuff inside?
The grey feathery structures are the gills, also called "dead man's fingers". They're not poisonous but they're inedible (tough, fibrous, and unpleasant to chew). Always remove and discard before eating or dressing.
