In order to form the intricate shape of the rosette, preheat your rosette iron in hot oil for about 20 seconds then dip into the batter. The heat of the iron will keep the batter on the form. Then place your rosette iron into the hot oil to deep fry. If your batter went over the top of the rosette form, your cookie will not shake off. Use the tip of a sharp knife to cut off any crispy batter on the top of the iron and help pry the cookie off the rosette iron.
