Recipe: Lobster Sauce

Put the coral and spawn of a boiled lobster into a mortar with a tablespoonful of butter; pound it to a smooth mass, then rub it through a sieve; melt nearly a quarter of a pound of sweet butter, with a wine-glass of water or vinegar; add a teaspoonful of made mustard, stir in the coral and spawn, and a little salt and pepper; stir it until it is smooth and serve. Some of the meat of the lobster may be chopped fine and stirred into it.
