Simit (Turkish), gevrek (Turkish; Macedonian: ѓеврек, Bulgarian: геврек, Serbian: ђеврек) or koulouri (Greek: κουλούρι) is a circular bread, typically encrusted with sesame seeds or, less commonly, poppy, flax or sunflower seeds, found across the cuisines of the former Ottoman Empire, and the Middle East. Simit's size, crunch, chewiness, and other characteristics vary slightly by region.In İzmir, simit is known as gevrek ("crisp"), although it is very similar to the Istanbul variety.
