272. New and Economical Lobster Sauce.—Should you require to use the solid flesh of a lobster for salad, or any other purpose, pound the soft part and shell together (in a mortar) very fine, which put into a stewpan, covered with a pint of boiling water; place it over the fire to simmer for ten minutes, then pass the liquor through a hair sieve into a basin; put three ounces of butter into a stewpan, into which rub (cold) a good tablespoonful of flour, add the liquor from the lobster, place it upon the fire, stirring until upon the point of boiling, season with a little cayenne, and add a piece of anchovy butter, the size of a walnut; or, if any red spawn in the lobster, mix it with butter, as in the last, and add it, with the juice of half a lemon, just before serving. An anchovy pounded with the lobster-shells would be an improvement, and part of the flesh of the lobster might be served in the sauce.
