In Sarajevo's old Baščaršija bazaar, ćevabdžinicas grill ćevapi from morning till late night, serving them ten at a time stuffed into a puffy, griddle-warmed somun flatbread with raw onion and a spoon of kajmak. The little skinless fingers are made from beef (often mixed with lamb), seasoned with nothing more than salt, pepper, garlic and a little bicarbonate of soda, which gives them their bouncy bite. Belgrade and Banja Luka have their own versions, but the idea is the same: smoky meat, soft bread, sharp onion. People often over-season them with herbs and paprika; the Bosnian way is plain, letting the meat and charcoal speak. Chef's tip: chill the shaped ćevapi well before grilling and turn them only once or twice, so they keep a juicy centre and a crusty outside.
