1/2 pound unsalted butter, very cold and cut into pieces
1 teaspoon kosher salt
3 ounces cold (iced) water
1 tablespoon sugar
In a food processor, combine flour, salt, and sugar, then pulse 3 times to incorporate. Add butter and pulse until ingredients look and feel like coarse meal. Now add water and pulse until a ball of dough is formed. Do not overmix. Turn dough out onto plastic wrap, cover, and refrigerate for at least 1 hour before rolling out.
