Mushroom Cheddar Tarts: Avid Baker's Challenge

This is my first foray into the Avid Bakers Challenge (ABC) group.  Thanks, Hanaa!

I'm having my book club at my house next week, and I thought that I'd use these as an appetizer if I liked the way they turned out, but I'm still undecided.

They're pretty good, but I wouldn't say they're amazing.  Easier to make than I thought, but they need some adjustments.

First, I think the proportions of dough to filling are way off.  I made a half-recipe of dough, and I had a lot left over, but didn't have nearly enough filling to use it all.  If I made them again, I'd make the same amount of dough, and the full recipe for the filling.

I rolled out the dough to a larger rectangle than the recipe recommends, but the dough was still much too thick for my taste.  When you eat a bite, you get a big hit of crust and just a bit of filling. And the filling needed something else--onion, garlic, herbs, olives?  Something.

Also, the crust (which I made in a food processor) needed a lot more water to be malleable.  I like recipes that hit the measurements right on the noggin.

They're much cuter made in individual tart pans than in mini muffin cups, and the flavor is better too (better filling to crust ratio).  I may call it a quiche and have one for breakfast.
