Refrigerate until firm, about 1 hour.Step 2Preheat oven to 350 degrees. Transfer dough to a lightly floured work surface. Roll out to a generous 1/8 inch thick. Using a 2 1/2-inch round fluted cutter, cut out wreaths. Reroll scraps, and cut out. Cut out centers of wreaths using a 7/8-inch round cutter. Space 2 inches apart on baking sheets lined with parchment paper. Refrigerate until firm, about 15 minutes. Bake until just golden, about 12 minutes. Let cool completely on wire racks.Step 3Stir together confectioners’ sugar and lemon juice in a small bowl. Dip surface of each cookie in icing, and sprinkle with pistachios. Let set on wire racks. Cookies can be stored in airtight containers at room temperature up to 1 week.
