Continue beating until mixture begins to thicken. remove from heat, and when the bowl has cooled a little, place it over cracked ice and continue stirring. When the mixture is on the point of setting, whip the cream and fold it in. Add the whiskey or Irish Mist.

Lastly, fold in the well-beaten egg whites. Pour into a soufflé dish that has a double thickness of parchment paper tied around it: the paper should come up 3 inches above the top of the soufflé dish.
