Sour Cherry Pie

We came back from vacation with a 10-lb bucket of frozen sour cherries.  What was I to do but immediately make a pie?  This recipe turned out great...full of cherries and not too sweet.  As I couldn't taste either the vanilla or almond extracts, I'm not sure if I would bother with them next time.  It wasn't the prettiest pie I've ever made, but that's what happens when it's 80+ degrees in the kitchen.

7) Place pie in refrigerator while oven preheats to 425 degrees.
