Food / LOOKING FOR A RECIPE ON POLISH BREAD [9]

Hi, I'm new to this website. My aunt used to make the best polish bread; unfortuantely, her recipe died with her. As I am not Polish, I don't know how to spell it, but it sounded like KOWATZ. I'm sure that's not correct. All I remember is it was a round bread, and had farmers cheese and egg on the top of it. It was absolutely the best bread ever, and I would like to be able to surprise my family with it. Any ideas?
