Halušky' can refer to the lumps themselves, or to the complete dish. Although recipes vary from region to region, in general flour is mixed with water and egg to form a batter. Potatoes are finely grated and mixed in the batter. Potatoes may be left out altogether. Traditionally, no special instrument was used to form halušky. Instead, dough was spread in a thin layer on a wooden cutting board and scraped off in even pieces (using a knife) and cast directly into boiling water. It is possible to form the dumplings as the batter is passed through a special perforated halušky strainer into boiling water forming small (1/2 X 2-3 cm) irregularly-shaped lumps. These are then rolled in butter or oil. Usually are served with meat or vegetable stews, cheese, bacon or ham. Bryndzové halušky is a typical Slovak traditional dish. In Hungary, galuska are often eaten with meat stews like Goulash or Pörkölt.
