Tsoureki , also known as شوريك ( Arabic), panarët ( Arbërisht), choreg or "chorek" ( Armenian չորեկ), çörək ( Azerbaijani), kozunak ( Bulgarian козунак), cozonac ( Romanian) or çörek ( Turkish)), is a sweet, egg-enriched bread, rooted in the cuisines of Europe and Western and Central Asia. It is formed of braided strands of dough. There are also savoury versions.
Such rich brioche-like breads are also traditional in many other countries, such as Hungary and the Czech Republic. Examples of similar breads from other cultures are badnji kruh in Croatian cuisine, folar de páscoa in Portuguese cuisine, Brioche in French, kulich in Russian cuisine, panettone in Italian cuisine and challah in Jewish cuisine.
