What is Dover sole?

The superior sole, Dover sole is a member of the flatfish family, fished from the North Sea to the Mediterranean. It has a light brown/grey speckled skin and a creamy underside. It has a firm but delicate and flavourful flesh and is best cooked as simply as possible. It's traditionally skinned on the darker side only, leaving the white skin of the underside in place. The skin separates easily from the flesh and the flesh falls easily from the bone.
