Mike, you should know that I've been working on an edible pie crust for years. Isabelle's French pie crust is probably my best effort. I used a recipe this time that called for beating vegetable shortening with boiling water - which to my surprise created something that looked a bit like whipped cream. Add the flour to that and roll out. It made a very light, layered, crispy type crust and I will probably try it again.
Chiffonade, that's a good idea and the next time I do this, I'd like to try it that way. It would increase the complexity of flavors to have a smooth savory custard inside. Though, 6 people managed to eat 24 tartlets so I guess people liked them.
The parmesan, btw, Mike, tied them together nicely.
