1 sq. semi-sweet baking chocolate
1 egg
1 tbsp. sugar
1/2 tsp. butter
1 tsp. vanilla

Place chocolate in 2 tablespoons coffee in a saucepan to melt. Add sugar and butter. Add 1 egg yolk at a time over low heat (use less yolks if more than 4 people). Beat egg whites until stiff. Add vanilla and mix by folding in chocolate mixture. Line a deep dish with ladyfingers vertically and on the bottom. Sprinkle liberally with rum, whiskey or Kahlua. Pour in mousse. Refrigerate overnight. You can top with whipped cream, or invert, then top with whipped cream.
