Put two middle-sized lobsters into boiling salt and water. When they are half boiled, take the meat from the shell, cut it into very small pieces, and put it into a pie dish. Break up the shells, and stew them in a very little water with half a dozen blades of mace and a wine-glass of vinegar. Then strain off the liquid. Beat the coral in a mortar, and thicken the liquid with it. Pour this into the dish of lobster to make the gravy. Season it with cayenne, salt, and mushroom catchup, and add bits of butter. Cover it with a lid of paste, made in the proportion of half a pound of butter to a pound of flour, notched handsomely, and ornamented with paste leaves. Do not send it to table till it has cooled. TO BOIL PRAWNS. Throw a handful of salt into a pot of boiling water. When it boils very hard, put in the prawns. Let them boil a quarter of an hour, and when you take them out lay them on a sieve to drain, and then wipe them on a dry cloth, and put them aside till quite cold. Lay a handful of curled parsley in the middle of a dish. Put one prawn on the top of it, and lay the others, all round, as close as you can, with the tails outside. Garnish with parsley. Eat them with salt, cayenne, sweet oil, mustard and vinegar, mixed together as for lobsters. CRABS Crabs are boiled in the same manner, and in serving up may be arranged like prawns. HOT CRABS. Having boiled the crabs, extract all the meat from the shell, cut it fine, and season it to your taste with nutmeg, salt, and cayenne pepper. Add a bit of butter, some grated bread crumbs, and sufficient vinegar to moisten it. Fill the back-shells of the crab with the mixture; set it before the fire, and brown it by holding a red-hot shovel or a salamander a little above it. Cover a large dish, with small slices of dry toast with the crust cut off. Lay on each slice a shell filled with the crab. The shell of one crab will contain the meat of two. COLD CRABS. Having taken all the meat out of the shells, make a dressing with sweet oil, salt, cayenne pepper, mustard and vinegar, as for lobster. You may add to it some hard-boiled yolk of egg, mashed in the oil. Put the mixture into the back shells of the crabs, and serve it up. Garnish with the small claws laid nicely round. SOFT CRABS. These crabs must be cooked directly, as they will not keep till next day. Remove the spongy substance from each side of the crab, and also the little sand-bag. Put some lard into a pan, and when it is boiling hot, fry the crabs in it. After you take them out, throw in a handful of parsley, and let it crisp; but withdraw it before it loses its colour. Strew it over the crabs when you dish them. Make the gravy by adding cream or rich milk to the lard, with some chopped parsley, pepper and salt. Let them all boil together for a few minutes, and then serve it up in a sauce-boat. TERRAPINS.
