                                            Blend flours, brown sugar, baking soda, salt, and butter in a large bowl with a pastry blender or your fingertips until mixture resembles coarse meal.

                                            Stir in buttermilk and eggs until a smooth dough forms. Transfer to a lightly floured surface and divide into 3 pieces. Form each piece into a 16-inch-long log and arrange, evenly spaced, on a lightly floured baking sheet. Generously sprinkle with flour and cut 3 diagonal shallow slashes on each log with a very sharp knife.

                                            Bake 30 minutes, then reduce oven to 375ºF and continue to bake until a wooden pick or skewer inserted into center of a loaf comes out clean, about 20 minutes.

                                            Transfer loaves to a rack to cool. Serve slightly warm or at room temperature. 
 
                        
                    
                    Cooks’ note: Soda bread is best the day it is made, but loaves can be tightly wrapped in 2 layers of foil and frozen 1 month. Refresh, wrapped in foil, in a 325ºF oven until heated through, about 20 minutes.
