To half a pint of good melted butter add three dessertspoonsful of essence of anchovies, a quarter of a teaspoonful of mace, and a rather high seasoning of cayenne; or pound the flesh of two or three fine mellow anchovies very smooth, mix it with the boiling butter, simmer these for a minute or two, strain the sauce if needful, add the spices, give it a boil, and serve it.
