In a medium bowl, combine together the flour and salt. Add the butter chunks and cut them into the flour mixture with a pastry blender, or two knives held together. You can also use a food processor for quicker work. Kids can do this with a fork if that is easier for them. Work these ingredients together until they form pea-sized crumbs.
Quickly stir in the cold water a tablespoon at a time and combine until a large pea size clumps form. Transfer these to the pie plate.
Pat the dough into a pie plate, pushing the dough across the bottom of the pie plate and up the sides.
Use as is in recipes that call for an unbaked pie shell. For recipes that call for a pre-baked crust, bake it for 10-15 minutes at 350 degrees until light golden brown. Cool completely before pouring in your filling.
