Toss the mixture until the butter is coated with flour
Add in the water in small amounts and mix with your other hand until the flour is almost all gone. Press the dough together and wrap in plastic wrap to chill at least one hour but overnight is best
To use dough, roll out dough between two pieces of parchment paper to ⅛" of an inch. Place into pie dish and press flat against bottom and sides. Trim off the excess, leaving ¼ of an inch around the outside of the pan to allow for shrinking.
