Place frozen bread balls on greased tray. Allow to thaw for several hours. When thawed, make 7 or 8 slices in bread, leaving the center intact. (To make larger pumpkin shaped breads, combine 2 rolls into one ball.) With your finger, press an indentation on the top of the roll. Whisk together egg yolk and water. Brush over rolls. Bake according to package instructions or until golden brown. When done, slice pecans in long pieces and press into the top of the bread for a “stem.”
