The shape of the season
Brown crab is available from around April through to November. What lands on the fishmonger's slab in April — newly active, lean from winter — is a different proposition to what you find at the height of summer. The classic crab-shack weeks, the dressed crabs eaten on harbour walls: those belong to high summer, when the crabs are full. Autumn brings quieter but still excellent fishing before the season closes for winter.
Outside those months, much of what you see has been stored or imported. It won't necessarily be bad, but it won't be British crab at its best.
Where the crabs come from
Cromer has its own devoted following — the small, famously sweet Norfolk crabs are worth a separate article. The national picture is bigger. Devon and Cornwall account for enormous quantities of the British catch, and much of it has historically left the country altogether, shipped to France and Spain where crab commands strong prices and enthusiastic markets. That export trade means a great deal of very good British crab has never reached a British table. Proximity to the south-west coast, or a fishmonger with direct links to south-west day boats, usually means access to crab that would otherwise head straight to the Continent.
Brown meat and white meat are not the same thing
A crab yields two quite distinct types of meat. They behave differently, taste different, and suit different things.
- White meat comes from the claws and legs. It is sweet, clean and delicate — the part most people picture when they think of crab. A large cock crab (the male) carries proportionally more of it, given its bigger claws.
- Brown meat comes from the body shell. It is rich, intensely savoury and much stronger in flavour — closer in character to a good pâté than to what most people expect from seafood. Hen crabs (females) are often favoured for it.
A properly dressed crab presents both, kept separate so you can taste each clearly. Many people who think they dislike crab have only ever encountered white meat from a tin, or brown meat stirred carelessly into something else. Side by side they make sense of each other: the sweetness of the white cuts through the depth of the brown, and vice versa.
The traditional approach is simple — brown meat spread on bread or toast, white meat alongside. It is a combination that has been eaten on the British coast for a very long time and has not needed improving.
How to buy it well
The phrase to look for is day-boat, pot-caught. Pot fishing — setting baited creels on the seabed — is selective and low-impact. Crabs caught this way come up alive and undamaged, not dragged through the water as trawl bycatch. Day boats go out and return within a day, so the crab reaches market quickly without extended storage at sea. Together, these are the closest thing to a reliable sustainability signal the crab market currently offers.
Live crab from a fishmonger who knows their supplier is the ideal. A dressed crab prepared in-house on the same day is the next best thing — ask when it was dressed. Pre-packed dressed crab from a supermarket is a more variable proposition; the brown meat suffers from sitting, and the two meats often get mixed during packing in a way that flattens both.
On the hen versus cock question: cock crabs yield more white meat, hen crabs more brown. Neither is superior — it depends on what you want to eat.
Making the most of it
British brown crab requires little intervention. Dressed brown and white meat on good bread, with something sharp alongside, is the format that generations of coastal eating have arrived at — it works because the crab is the point, not what surrounds it. Buy from someone who can tell you where it came from and when it was landed, and you are most of the way there.
