04Pulse the walnuts with the sugar, in a food processor until fine and powdery, about 2 minutes. Add the flour, spices, and salt, pulsing until evenly combined. Add the butter, yolks, and brandy and pulse until the mixture starts to come together. Stop mixing and pull the dough together by hand, press and roll into a thick log about 8 inches long.05Cut the log crosswise into 12 equal pieces. (If the dough is very sticky, refrigerate it until easier to work with, about 30 minutes.) Lay 8 pieces of the dough on the bottom of the pan. Press and spread the pieces together with your fingertips to cover the pan evenly.06Stir the cherry jam, lemon zest and juice together in a bowl. Spread the mixture evenly over the surface of the dough with the back of a spoon.07Roll the remaining dough out on a well-floured surface about 1/8-inch thick. Use a small decorative cutter, such as a leaf, tree, or star, to cut the dough into 24 pieces. Evenly place the pieces on top of the filling in 6 rows of 4. Alternatively cut the dough into long strips with a pizza wheel or knife, and place them on the filling in a lattice pattern; or cut the dough into ovals and lay them on the filling in a decorative pattern. Brush decorative layer of dough with egg white.08Bake the squares until golden brown, about 40 to 45 minutes.09Cool completely in the pan on a rack. Cut with a serrated knife into 2-inch squares.10Copyright (c) 2004 Television Food Network, G.P., All Rights Reserved.
