Mint White Chocolate Mousse

4 oz Chocolate, white
3 tb Creme de menthe, green
1 c Cream, heavy
2 Egg whites (at room temperature) Melt the white chocolate in a double boiler. When melted, stir in the creme de menthe. Let it cool a bit and stir in about 2 1/2 T of cream. Let cool. Beat the egg whites until stiff, but not dry. Fold the chocolate-creme- cream mixture into the beaten egg whites. The more carefully you fold, the lighter will be the mousse. Whip the remaining cream, until soft peaks form. Fold the egg whites- chocolate mixture into the whipped cream. Again, the more air you preserve, the lighter the mousse. Spoon carefully into small bowls or cups and chill for about two hours.
