How to do it:
In a saucepan, melt butter, clarify and set aside. In a separate saucepan, combine vinegar, vermouth, green onions, parsley, tarragon, chervil, and peppercorns. Over high heat, reduce this liquid until it barely covers the bottom of the pan. Cool the mixture by setting the pan in cold water before adding the eggs. In a heavy saucepan, not over heat, place egg yolks, water and cooled reduced vinegar mixture, beating with a wire whisk until frothy, approximately 3-5 minutes. Place over low heat and continue beating vigorously several minutes longer. The pan should be removed from the heat often during this process to ensure slow cooking. Beat constantly until it is the consistency of a thick cream sauce.
Remove the pan from the fire, and while continuing to beat, slowly add clarified butter to the mixture a tablespoon at a time until all the butter is used. Add salt, parsley or chives, while beating in well. If mixture curdles, add 1 tablespoon cold water and beat vigorously. To prevent scum from forming on the top, cover the sauce with 6 thin slices of butter and place on top of the stove near the pilot light or place in a double boiler over lukewarm water. You may add a tablespoon of warm water and beat again before serving.
