What is "kalacs"

Kalács (pronounced ) is a Hungarian sweet bread very similar to brioche, usually baked in a braided form, and traditionally considered an Easter food. The word comes from the Slavic languages (originally from the Old Slavonic word kolo meaning "circle", "wheel") and refers to the original rounded form of the bread. Similar types of bread also exist in other Central European and Eastern European countries, such as Kalach in Ukraine and Russia.
