A too cute idea from http://www.ourbestbites.com/2009/09/single-serving-pie-in-jar.html . This is a great gift-giving idea for a wedding, party favors or everyday. The half pint jars with wide mouth and straight sides can be purchased and/or ordered from your local hardware store, Amazon, Fred Meyer's or a feed store for about $9. Also, keep a lookout at garage sales. The jars are made of tempered glass and can handle the heat. Vary the fillings and it has been suggested making pumpkin or even chicken pot pies. These can be baked immediately, but designed to be baked frozen. Keep the heat high to promote a crisp crust, otherwise a lower heat will melt the butter producing a soggy crust. Don't worry about how long these can be frozen for they probably won't last that long. One more tip, it has been suggested to place a silpat sheet on the bottom of the baking sheet to prevent the cups from sliding around. For best show, allow to cool and pop the pies from the jars onto a serving plate.
