Surprisingly light, these scrumptious doughnuts are made with egg-whites and starch, and slathered in rose-water syrup . The name is probably a corruption of kāhin or kahīn, meaning ‘soothsayer’ and ‘magician’, respectively. [Ibn Mubārak Shāh, fol. 20v.] They become even more irresistible when you sprinkle on some icing sugar.
