                Cornmeal lends these crackers a golden glow and a nice crunch; lots of crushed green peppercorns (left over from Chicken Spice Rub) provide an intriguing spiciness. Serve them with cheese or all on their own with cocktails.

Whisk together flours, cornmeal, baking powder, baking soda, brown sugar, 2 tsp peppercorns, and table salt in a bowl. Blend in butter using a pastry blender or your fingertips until mixture resembles coarse meal. Add buttermilk and stir just until a dough forms. Turn dough out onto a floured surface and gently knead 6 to 8 times. Cut into 5 pieces, then chill, covered with plastic wrap, 10 minutes.

Roll out 1 piece of dough on a well-floured surface with a floured rolling pin into a 15- by 4-inch rectangle (1/8 inch thick). Lightly brush with egg, then prick all over with a fork. Sprinkle with about 1/2 tsp salt-and-pepper mixture.

Cut crosswise into 12 strips and arrange 1/8 inch apart on a parchment-paper-lined baking sheet. Repeat with remaining dough.

Bake, switching position of sheets halfway through, until golden-brown and crisp, 20 to 25 minutes. Cool crackers slightly, then transfer to racks to cool completely.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: Crackers keep in an airtight container at room temperature 1 week.
