Preparing a whole crab will take you 40 minutes or so, but it’s well worth the effort to enjoy the sweet meat at its freshest. Monica Galetti, chef and BBC Masterchef judge, says ‘Preparing a crab yourself works out much cheaper than buying ready-picked meat, plus the flesh is tastier and you know just how fresh it is. I love crab – my earliest memory of eating it is being a child in Samoa, devouring my mum’s crab curry.’
Buying a crab
Whether it’s cooked or live, choose a crab that feels heavy for its size and smells fresh. If it’s alive, make sure it looks fairly active. Crabs are best cooked immediately after killing, so ask your fishmonger to kill the crab, then take it home and cook it as soon as you can. Never buy a dead uncooked crab, as you don’t know when it was killed and it may no longer be safe to eat.
How to cook a crab
Bring a large pan of well-salted water to the boil. Lower in the crab, simmer for 12 mins per kg, then leave to cool a little in the liquid. Transfer to a tray, place in the fridge and leave to cool completely.
How to prepare a crab
You will need…
- 1 large cooked crab or 1 large live crab (see Buying a crab, above)
- 2 bowls
- A large knife
- A lobster pick or skewer
- A hammer, kitchen mallet, knife sharpening steel or heavy rolling pin
Lay the crab on its back, twist off the claws and legs, and set aside.
Use the palm of your hand to push down on the crab. Get your fingers between the gap where the body meets the shell and pull upwards.
Pulling quite hard, completely separate the crab body from the shell – it will come off in one piece.
Pull away and discard the feathery gills (also known as dead man’s fingers) – these are found around the main body and inside the shell.
Use a spoon to scoop out the brown meat from the shell and transfer it to a bowl.
Use a large knife to cut the main body in half.
Using a lobster pick or skewer, pick the white meat out of the cavities in the body and put in a separate bowl. It’s worth taking your time to do this, as there is a surprising amount of meat in all the small crevices.
Crack the claws and legs using a heavy object like a hammer, kitchen mallet, knife sharpening steel or rolling pin. Try to break them with one sharp tap – you don’t want the shell to shatter into very small pieces as they will be difficult to find.
Carefully remove the meat using a lobster pick or teaspoon. Discard the cartilage in the middle of the claws and legs. Add the meat to the bowl of white meat, then check the bowl for stray shell by shaking it from time to time – shell fragments ‘ping’ against the side of the bowl and can be removed.
