Into a large bowl sift together flour, sugar, baking powder, salt and soda.
Cut in the butter until the mixture is crumbly. Add egg, orange zest and orange juice all at once. Stir just until the mixture is evenly moist. Fold in
the cranberries. Spoon the batter into a greased 9x5x3-inch loaf pan. Bake
at 350 degrees F. for 1 hour and 10 minutes, or until toothpick comes out clean. Remove from pan and cool on wire rack.
