Combine flour and sugar in a large bowl.
Cut in butter ¼ cup at a time until mixture resembles crumbs.
Add cold water and form into a ball.
Seperate ball into two (I like to make one ball slightly bigger than the other for the bottom crust.
Wrap balls in saran wrap and refrigerate for about 10 minutes or so to help with rolling out.
Throw some flour on your board or counter and roll out dough. Place bottom piece in pie pan and mold edges.

Place foil over crust edge to keep from burning, make sure to tent it and not press against the crust.
Bake at 450 degrees for about 45 minutes or until golden and bubbly.
