Ingredients

2 1/2 cups all-purpose flour 

1 teaspoon salt 

2 teaspoons sugar 

15 tablespoons cold unsalted butter, cut in pieces 

3 tablespoons vegetable shortening 

Preparation

In the bowl of a food processor, combine flour, salt, and sugar. Add butter and shortening; pulse until mixture resembles coarse meal. Add 1/4 cup ice water in a slow, steady stream through the feed tube, pulsing, until mixture holds together. If necessary, add more ice water, 1 tablespoon at a time, until dough holds together when squeezed. Form dough into a ball; cover with plastic wrap. Flatten into a disk; refrigerate at least 1 hour.
