My dad used to get these as a kid in NYC and fry with onions, serve with fried eggs and rye toast. Yum.
Arax recently had some whole smoked herring from Brooklyn NYC. They said "cold smoked" but really they were almost hot smoked. In fact they were really like fat juicy very salty kippers. I fried em, and they were amazingly delicious, but very salty. A perfectly acceptable substitute for kippers.
But, that said, now I am thinking about kippered herring. Anyone seen em in Boston?
