Add the milk mixture, lemon zest, salt, remaining sugar and 1-1/2 cups flour to yeast mixture; beat until smooth. Add eggs; beat on medium speed for 1 minute.

Roll up jelly-roll style, starting with a long side; pinch seam to seal. Place seam side down on a lightly greased baking sheet. Pinch ends together to form a ring., With scissors, cut from outside edge to two-thirds of the way toward the center of the ring at 1-1/2-in. intervals. Separate strips slightly; twist so filling shows. Cover and let rise in a warm place until doubled, about 45 minutes., In a bowl, combine egg and 1 tablespoon milk. Brush over dough.
