Combine flour, corn starch, confectioners' sugar and nuts in a large bowl. With a large spoon, blend in butter. Work with hands until soft, smooth dough forms.
Shape dough into a smooth roll, about 1 1/2-inch (4 cm) in diameter. Wrap and chill until firm (about 4 hours, or overnight). Roll can be stored in the refrigerator for up to 1 month.
Cut with sharp knife into thin slices. Place on ungreased baking sheet.
Bake at 375°F (190°C) for 8 to 12 minutes, or until edges are lightly browned. Transfer to wire rack to cool.
Makes about 3 dozen cookies.
