It is also traditionally made in Vojvodina, Serbia, where it was introduced by the local Hungarians.The dough for lángos is made of water or milk and flour, yeast, sugar and salt.Adding sour cream, yoghurt or mashed potatoes to the dough is optional, in the latter case it is called potato lángos (in Hungarian krumplis lángos). It is eaten fresh and warm, topped with sour cream and grated cheese, or Liptauer, ham, or sausages, or most frequently, without toppings, just rubbed with garlic or garlic butter, or doused with garlic water.
