                    Friends look forward to receiving a gift of these crescents. They're my all-time favorite cookies. The pastry is tender and flaky, and the vanilla flavor comes through beautifully.  Ingredients: 
                    
                        
                                                2 cups king arthur unbleached all-purpose flour  |  
                                                1/8 teaspoon salt  |  
                                                1 cup cold butter, cubed  |  
                                                1 egg, separated  |  
                                                2/3 cup sour cream  |  
                                                1/2 teaspoon vanilla extract  |  
                                                2/3 cup finely chopped walnuts  |  
                                                2/3 cup sugar  |  
                                                1 teaspoon ground cinnamon  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. In a large bowl, combine flour and salt; cut in butter until mixture resembles coarse crumbs. In a small bowl, whisk the egg yolk, sour cream and vanilla; add to crumb mixture and mix well. Cover and refrigerate for 4 hours or overnight. 2. Divide dough into thirds. On a lightly floured surface, roll each portion into a 10-in. circle. Combine the walnuts, sugar and cinnamon; sprinkle 1/4 cup over each circle. Cut each circle into 12 wedges. 3. Roll up each wedge from the wide end and place point side down 1 in. apart on greased baking sheets. Curve ends to form crescents. Whisk egg white until foamy; brush over crescents. Sprinkle with remaining nut mixture. 4. Bake at 350° for 18-20 minutes or until lightly browned. Remove to wire racks to cool. Store in an airtight container. Yield: 3 dozen.                              |
