Crisp Fish Skin

Fish skin is not often thought of as a true delicacy; in fact, many consider it to be inedible. It has a fat content of up to 10 percent, which is greater than that of the flesh, and consists of two layers, a thin outer layer and a thicker inner layer, called the dermis, which is mainly made up of large quantities of connective tissue. Many fish have large scales that must be scraped off first and it is common to find a layer of mucus on the surface of the skin that helps protect the animal from attack by microorganisms. Among other things, the mucus contains glycoproteins.
