Preparation:

Place flour, sugar and salt in a food processor fitted with the steel blade. Pulse the mixture to combine. Add butter and shortening; pulse until the fat is evenly cut in and the mixture resembles coarse cornmeal. Transfer mixture to a mixing bowl. Working quickly, gradually add enough cold water while tossing and stirring with a fork so the dough just begins to stick together. Divide dough into two equal-size portions, flatten into rounds, wrap in plastic and chills several hours or overnight.
