Proja (Cyrillic: Пpoja) is a Balkan dish made of corn flour, baking powder, sunflower oil, sparkling water and salt. Proha is an alternative name used in Bosnia-Herzegovina.
It used to be popular in times of widespread poverty, mostly before the 1950s, but is now a common everyday meal. It is often mistaken with projara, a somewhat fancier variant of proja, which includes the additional ingredients flour, eggs and yogurt.
The ingredients should be mixed together, and baked in a greased pan (which should be 5 cm high) until golden. Best served with Sauerkraut (Kiseli kupus) and Pavlaka.
