My neighborhood Gristedes (!) has packages of "smoked herring", in with the meats and fish. These don't look like anything I'm used to -- not like chubs, or kippered herring. They look like big, dry anchovy filets, 4 or 5 inches long, dark brown and flat, and packed a bunch (?) to a container. I asked the fish guy what to do with them, but he just rolled his eyes and said, "Cook 'em". Thanks a bunch.
So my question: what are they, and what do I do with them? Thanks
