Génoise

—put two ounces of butter in a small saucepan, set it on the fire, and when melted, mix in it a tablespoonful of flour; stir for one minute, add one-fourth of a carrot, sliced, stir now and then, and when nearly fried, add also a pint of broth, half a pint of claret wine, a small onion, and a clove of garlic, chopped; two cloves, a bay-leaf, two stalks of parsley, one of thyme, salt, and pepper; boil gently about one hour and forty minutes, and strain. If it boils away, add a little broth. Put it back on the fire with about half an ounce of butter, boil gently for about ten minutes, and it is ready for use. This sauce is excellent with any kind of boiled fish, but especially with trout, pike, and pickerel.

A trout served with a génoise sauce is considered a recherché dish.
