Flounder and Sole are the names given to most U.S.
flat fish and once on the plate it nearly impossible to tell what
species it is.
The term flat fish describes a species that is
born swimming upright and as it matures it rolls over on its
side. Also, when they are born they have an eye on each
side. After they roll over both eyes work their way to the side
that is on top.
A
flat fish is easy to filet as they do not have many pin bones to work
around. A European Dover Sole is the true original sole and it is
the most expensive. It is imported from Europe The U.S. Dover sole
is found along the west coast from California to Alaska.
Some of the other species, identified by the side
their eyes are on, are Fluke, Blackback Flounder, Witch Flounder, Sea
Dab, Yellow Tail Flounder, Southern Flounder, Pacific Sole, Butter Sole,
Rex Sole, Rock Sole, Yellow Fin Sole, Summer Flounder and Pacific Sand
Dab. These are all sold as Flounder and Sole.
