Jane Grigson's Fish Book - Jane Grigson [56]
Of course you will not agree with me – particularly if you live in Maryland, where crabs have restaurants to themselves. I am not sure if I agree with myself either, having tasted now the sweet spider crabs from the Atlantic coast of France; but those Cullercoat crabs set up a standard of deliciousness in my memory, however embroidered by time, which I cannot escape from. The point is that in this country at least, crab is a luxury that many people can afford, without feeling guilty. The price of lobsters have soared, scallops have joined them, oysters are not yet the poor man’s food, as they once were and as they may be again. Prawns and scampi, toughened by freezing, are a disappointment. But fresh crabs, like fresh mussels, are an unalloyed pleasure.
Unless your fishmonger is beyond reproach, the crab you boil yourself is far superior to the ready-to-eat kind. Be wary about ready-to-eat crab meat too. Sometimes it is mixed with foreign substances to pad it out. This may be approved by health inspectors, but does absolutely nothing for the true crab. Crab is a rich filling substance – it should not be weighed down by stodgy and concealed matter.
There is no way out of it. Boiling and excavating your own crab is best. It is also a pleasure. Particularly if you can find someone to read to you, as you jab away.
HOW TO PREPARE CRABS
The point of success lies in salting the water adequately. Even seawater needs extra strength. An egg should float in the brine – use about 175 g (6 oz) salt to 2–2¼ litres (3½–4 pt) of water. Put in the crab, fasten on the lid, and bring it to the boil, or rather to the simmer. Give it 15 minutes for the first 500 g (1 lb); 10 minutes for the second, third and so on. Remove from the pan to cool.
When the crab is cold, lay it on its back. Twist off the legs and claws. Push back and remove the pointed flap, and take out the central body part – a large mass of thin bone, crab meat and ‘dead men’s fingers’. Remove the small mouth part, too, by pressing down on it: it will snap away.
Have two basins ready. Scoop out all the soft yellowish-brown meat from the shell – the best part – and put it in one basin. Add any yellowish meat still adhering to the central body. Crack the large claws and remove the sweet pinkish-white meat and put it into the second basin. The quick part of the work is now over. Settle down with a larding needle or crochet hook, a small mallet and a teaspoon, and poke out all the residue of delicious white fibres from the central body, and the meat from the legs. Be careful not to add tiny pieces of thin shell to the basin. A good ¾–1 kg (1½–2 lb) crab can yield 375 g (12 oz) of edible deliciousness if you are prepared to be a little patient. This is enough for three people, or more if you are going to add sauces, salad ingredients and so on.
The large shell can be turned into a container for the crab. You will notice a beautifully curved line on the undershell. Give a few hard taps on the inner side of it, by the gaping hole, and the rough pieces will fall away along the line. Scrub out the shell, and brush it lightly with oil if you want to give it a gloss.
CRAB MAYONNAISE AND CRAB LOUIS
A good way of serving crab is to make it the focal point of a large salad. There is nothing original in the idea. To the usual ingredients, add slices
