Carp Sauce, for Fish.
Put a little lean bacon and some slices of veal at the bottom of a stewpan, with three or four pieces of carp, four anchovies, an onion, two shalots, and tarragon, or any root to flavour to your taste. Let it remain over a very slow fire for half an hour, and, when it begins to thicken, or to stick to the pan, moisten it with a large glass of white wine, two spoonfuls of cullis, and the same quantity of broth. Skim and strain it through a sieve; it will want no salt.
