Reduce to a paste in the mortar the spawn, shell, and creamy parts of lobster. Add their equal in weight of butter and strain through sieve.

Lobster Butter

Pound three ounces of lobster trimmings and spawn, if any, and a little of the coral with four ounces of butter. Rub through a fine sieve. (If no coral, cochineal will do.)

Lobster Butter

Procure half a lobster, quite full of spawn, which take out and pound well in a mortar; then add six ounces of fresh butter, mix well together, then rub it through a hair sieve, and put it in a cold place until wanted. The flesh can be used for any other dish.
