Sauce Bearnaise

To make this admirable sauce—a souvenir of the mountain home of Henri de Navarre—put in a saucepan two tablespoonfuls of chopped shallots (small green onions), and four of white wine vinegar. Reduce to one half. Add six yolks of eggs, two tablespoonfuls of beef extract and stir on the fire with a wooden spoon, until it thickens. Put a little to the side, and add, a bit at a time, a half pound of good table butter, dropping a little water in when the sauce becomes too thick. Press through a napkin. Finish with finely chopped tarragon, chervil, parsley, and a pinch of red pepper.
