1 teaspoon salt
1 teaspoon sugar
1 cup cold butter cut into pieces
1/4 to 1/2 cup Ice water
(you have to judge the amount of water, I don't usually need all the water)
In a large size bowl put in flour, salt and sugar. Add cut up pieces of butter and work with your fingers until crumbly or use a pastry cutter. Some small chunks is ok.
Remove one of the pieces of dough and roll the dough on a floured surface, I like to sandwich the dough between dusted waxed paper (dust with flour). Then roll out the dough until thin. Place the rolled out pastry dough into your pie pan.
The pie filling
