Pie Crust

1/4 cup butter
1/4 cup shortening
1 1/4 cups all−purpose flour
1 tablespoon sugar
1/4 teaspoon salt
1 egg yolk
2 tablespoons ice water
1/2 teaspoon vinegar

Beat together butter and shortening until smooth and creamy; chill until
firm. Sift together flour, sugar and salt in medium bowl. Using fork, cut
butter and shortening into dry ingredients until mixture has a consistent
texture. Mix egg yolk, ice water and vinegar into dough, then form into ball
and refrigerate about 1 hour.
Preheat oven to 450 . When dough has chilled, roll it out and press into pie
plate. Press parchment paper or aluminum foil into crust and weight crust
down with ceramic pie weight or another pie plate filled with dried beans.
Bake 15 minutes, then remove weight or pan filled with beans and prick crust
with fork to allow steam to escape. Bake another 5−10 minutes or until crust
is golden brown. Let crust cool.
Makes enough dough for one 8− to 10−inch single crust pie.
