Sweet fish? Feh! Our gefilte fish was always made with salt an pepper and always from fresh ground, never from a loaf.. When I was married, my mother,O’H had to teach my kallah how to make proper gefilte fish as her family was from south of the Gefilte Fish Line (look it up) and always made sweet fish (did I already say feh?).
Incidentally, the Gefilte Fish Line is also the demarkation between proper Yiddish pronunciation and Galitzianer pronunciation.
