This recipe was created to prepare Dried-Fruit Tart with Brandied Crème Anglaise.
Makes enough dough for an 8- to 10-inch tart.
Cut butter into pieces and soften to cool room temperature. In a food processor pulse walnuts until finely ground. Add confectioners' sugar, flour, and salt and pulse until combined. Transfer mixture to a large bowl and add butter.
With your fingertips or a pastry blender blend together flour mixture and butter until most of mixture resembles coarse meal with remainder in small (roughly pea-size) lumps. Stir together yolk and ice water and add to mixture. With a fork toss mixture until liquid is incorporated. Gently form mixture into a ball and on a lightly floured surface smear dough in 3 or 4 forward motions with heel of hand to help distribute fat and make dough easier to work with. Form dough into a ball and flatten to form a disk. Chill dough, wrapped in plastic wrap, 1 hour, or until firm but not hard. (Dough may be covered and chilled 1 day ahead or frozen 1 month.)
