  • 8 large eggs, separated
  • ¼ teaspoon cream of tartar
  • ½ cup butter, melted
  • 1 pinch salt

Method

Melt chocolate and butter together in a double boiler. Whip egg whites until soft peaks form. Add sugar 2 tablespoons at a time. Add cream of tartar. Set aside. Whip egg yolks until they appear thick and lemony. Add vanilla. At low speed, add melted chocolate, butter, and salt. By hand fold 1/4 of meringue into chocolate mixture, then fold chocolate into meringue, gently but briskly. Bake at 350 for 35-45 minutes in a water bath.
