They take a bit of work to get set up. And if you aren't careful, they can be a little messy to put together. But they are SO good that it doesn't matter at all. I even put them together about two hours before I needed to bake them and stuck them in the fridge until it was time to eat.

And here they are after coming out of the oven. They were really crispy and even better than fried!
I love, love, love this cookbook!
