This was Dancer's first pie crust and it turned out nice and flaky. She filled it with chocolate pudding and it was gone in no time!
Potato Pie Crust
1 cup sifted flour - yes, you really should sift it.
1/2 tsp. salt
1/2 tsp. sugar
1/2 cup cold plain mashed potatoes - don't add milk or butter when mashing
2 tbsp. cold water
6 tbsp. shortening
Sift flour, salt and sugar. Blend in potatoes until mealy. Cut in shortening until mixture consists of small crumbs. Sprinkle water and cut in one tablespoon a time. Form into a ball and refrigerate for 1/2 hour.
Roll out dough on lightly floured surface to 1/8 inch thickness. Put in pie pan and crimp edges. Prick pastry all over.
