IN BOSNIA proper burek is with chopped  meat not minced meat. and its my favour. and there is actually good reason for that coz in chopped meat you cant put all kinds of additives as you can do with minced. they put all kind of stuff like soya pumpkin and other stuff mixed with minced meat so that in the end cant see difference in that mass of meat. really ugly way to make a profit on cheating on the meat. and yes they also mix it with soda bycarbona. so when in restoran or some place you want to eat burek ask for chopped meat, and sure it is better
