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.
