5. Sauce Piquant.
Cut up a small onion, chop two beads of garlic, and fry in two ounces of butter with twelve cloves, twelve peppercorns, and three bay-leaves. Add half a pint of milk. Let it slowly come to the boil.
Have ready one tablespoon of flour mixed smooth with a little cold milk, stir into the boiling milk, strain, let it cool a little; now add the yolk of an egg well beaten, a little Nepaul pepper and salt to taste. And lastly, chop up some tarragon and a little chervil that has been soaked in vinegar for a week previously. Add this very carefully, a little at a time, so that the sauce does not curdle. This sauce is a great favourite.
