Make a cream-sauce with one pint of cream and set it on a moderate fire; immediately turn into it, stirring the while, about half a pint of reduced, good meat gravy; when thoroughly mixed, add two or three ounces of butter, stir for a couple of minutes longer, strain and use immediately.
It is a very rich sauce, used with boiled fish and roasted or baked meat.
