A frozen souffle is basically a mousse (meringue, flavoring and whipped cream) that is frozen. You get the souffle, or risen, effect by wrapping something firm around the souffle cup and filling it with mousse. I used a strip of cellophane that extended above the top of the cup. After freezing, the wrapping is removed and the frozen souffle appears to have risen. The happy thought is that it isn't as likely to fall as a regular souffle!
The consistency isn't as smooth as good ice cream but it is still a nice summer dessert. I think I'll flavor the next ones with liqueurs. That should put me in the party spirit.
