Street Food of Prague, Czech Republic. The Lángos, a Hungarian food speciality

Lángos is a Hungarian food speciality, a deep fried flat bread made of a dough with flour, yeast, saltand water. It is also traditionally made in Vojvodina, Serbia, where it was introduced by the local Hungarians.

Lángos is a dough made of water or milk and flour, with a dash of sugar and salt and fried in oil. 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. Other ingredients and accompaniments can be mushroom, quark cheese, eggplant, cabbage, kefir, omelet, and a confectioner's sugar or jam. It is popular all year long. As it is a rather affordable and simple food, it is often sold around bus stations (where commuters can purchase it), fairs, and all over Eastern European countries on local celebrations or sport events.

Traditionally lángos was baked in the front of the brick oven close to the flames. This is the basis for its name; "láng" means "flame" in the Hungarian language. Lángos was made from bread dough and was served as breakfast on the days when new bread was baked. Now that people no longer have brick ovens and do not bake bread at home, lángos is virtually always fried in oil.

Lángos is sold at many fast-food restaurants not only in Hungary but also in Austria. In Austria, especially in Vienna, lángos is very popular as a fast food at fairs and in amusement parks like the Prater. Lángos is known in the Czech Republic, Slovakia and Croatia as langoš, in Serbia as languš (although it is commonly called "Mekike"). It is also popular in Romania as langoși.
