Herring Pickled, Kippered, Canned, Dried etc.
Herring is a small oily fish that preserves well in varous ways, and all these ways are exploited. The photo shows two styles of pickled Atlantic herring from Poland, a major herring eating country. Yummm!

Technically, kippered herring are herring that have been split open, salted
and smoked. They are made during the spawning season when the fish don't
taste very good without this treatment. Most Americans have never seen a
real kippered herring but are familiar with the version that comes in a can,
generally called "kipper snacks". Kippers are a breakfast staple in the
British Isles and Scandanavia.
These salted and dried Tunsoy herring are much in evidence in Philippine
groceries. I'm not yet sure what to do with them but I'm working on it.
