1 1/4 cup flour
1/4 tsp salt
1/2 cup butter (cold)
1/4 cup water (ice cold)
Whisk or sift flour and salt together. Cut in butter. Toss mixture with a fork and add water one drop at a time.
Make a ball, cover in wax paper and plastic wrap, and chill it 2-24 hours.
Roll it out and use it.
FOR A BASIC 9" DOUBLE CRUST (a pie with both a bottom crust and a top crust):
Double the ingredients and prepare the dough as above. Before forming the ball, divide in half and form 2 balls. One will be the top crust, one will be the bottom crust.
