I do use a food processor to make my pie dough, it works for me, but feel free to do it the old fashioned wayCube cold butter and shortening into 1/4 inch pieces.
Sift flour, sugar, and salt together and place into the bowl of a food processor. Pulse 2 times.
Add butter and shortening pieces to flour and pulse 2-3 seconds until it forms a fine crumb.
Add Ice 5 Tablespoons of Ice Water to the mix and Pulse 2-3 seconds until dough forms on the blade. Add one more Tablespoon of Ice water if the dough seems too dry.
Remove dough from bowl, shape dough into a ball ( do not work the dough more than you need to, that will make it tough)
Wrap in plastic wrap and refrigerate for at least an hour or up to 2 days.
When the dough is ready place it on a lightly floured surface and roll it out with a lightly floured rolling pin.
Roll dough from the center to the edge to keep the dough round. The dough should be about 1 1/2 inches bigger than your pie dish.
Roll dough onto a rolling pin and transfer to the pie plate. Form to pie pan and from your decorative edge.
Keep the dough cold until you are ready to fill it.
Preheat oven to 375 degrees
