Parboil the lobster in boiling water well salted. Then pick out all the meat from the body and claws, and beat it in a mortar with nutmeg, mace, cayenne, and salt, to your taste. Beat the coral separately. Then put the pounded meat into a large potting can of block tin with a cover. Press it down hard, having arranged it in alternate layers of white meat and coral to give it a marbled or variegated appearance. Cover it with fresh butter, and put it into a slow oven for half an hour. When cold, take off the butter and clarify it, by putting it into a jar, which must be set in a pan of boiling water. Watch it well, and when it melts, carefully skim off the buttermilk which will rise to the top. When no more scum rises, take it off and let it stand for a few minutes to settle, and then strain it through a sieve.
Put the lobster into small potting-cans, pressing it down very hard. Pour the clarified butter over it, and secure the covers tightly.
Potted lobster is used to lay between thin slices of bread as sandwiches. The clarified butter that accompanies it is excellent for fish sauce.
Prawns and crabs may be potted in a similar manner.
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 grated nutmeg. 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 ten ounces of butter to a pound of flour, notched handsomely, and ornamented with paste leaves. Do not send it to table till it has cooled.
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.
