Fish for making gefilte
I'm not sure if they would grind it for you....but if you're in the Baltimore area( although they are probably in the DC area also) the fresh fish selection at Han au Rhem ( I'm sure I've spelled that wrong!)....the Asian market on Balt. National Pike in Catonsville has an amazing selection of the fish you are looking for. I would also use whitefish in the mix....which they have.
