Sauce for Carp and Tench.
Boil a pint of strong gravy drawn from beef, with three or four anchovies, a small bit of lemon-peel and horseradish, a little mushroom ketchup, and a great deal of black pepper. When boiled enough, strain it off, and when it is cold take off all the fat. Then add nearly half a pound of butter, well mixed with flour, to make it of a proper thickness. When it boils, add a cupful of red wine and a little lemon-juice.
