Actually, I've never had a parfait I've liked. Sure, the name -means- perfect, but most commercial ones are layer of gelatin and edible oil product masquerading as whipped cream. Wikipedia claims they can be many-layered sundaes, too, but even then . . . why bother? I'll take one flavour of really good ice cream over layers of conflicting ones and sauces. :-) Keep it simple, and all.

As for the Cathar priest . . . haven't tried one, and don't plan to. :-)
