Kipper

A kipper is a whole herring, a small, oily fish, that has been split into a butterfly fashion from tail to head along the dorsal ridge, gutted, salted or pickled, and cold-smoked over smouldering woodchips (typically oak).

In the United Kingdom, the Isle of Man, Japan, and a minority of North American regions, they are often eaten for breakfast. In Great Britain, kippers, along with other preserved smoked or salted fish such as the bloater and buckling, were also once commonly enjoyed as a high tea or supper treat, most popularly with inland and urban working-class populations before World War II.

The English philologist and ethnographer Walter William Skeat derives the word from the Old English kippian, to spawn. The word has various possible parallels, such as Icelandic kippa which means "to pull, snatch" and the Germanic word kippen which means "to tilt, to incline". Similarly, the Middle English kipe denotes a basket used to catch fish. Another theory traces the word kipper to the kip, or small beak, that male salmon develop during the breeding season.

As a verb, kippering ("to kipper") means to preserve by rubbing with salt or other spices before drying in the open air or in smoke. Originally applied to the preservation of surplus fish (particularly those known as "kips," harvested during spawning runs), kippering has come to mean the preservation of any fish, poultry, beef or other meat in like manner. The process is usually enhanced by cleaning, filleting, butterflying or slicing the food to expose maximum surface area to the drying and preservative agents.

Although the exact origin of the kipper is unknown, this processes of slitting, gutting, and smoke-curing fish is well documented. According to Mark Kurlansky, "Smoked foods almost always carry with them legends about their having been created by accident—usually the peasant hung the food too close to the fire, and then, imagine his surprise the next morning when …". For instance Thomas Nashe wrote in 1599 about a fisherman from Lothingland in the Great Yarmouth area who discovered smoking herring by accident. Another story of the accidental invention of kipper is set in 1843, with John Woodger of Seahouses in Northumberland, when fish for processing was left overnight in a room with a smoking stove. These stories and others are known to be untrue because the word "kipper" long predates this. Smoking and salting of fish—in particular of spawning salmon and herring which are caught in large numbers in a short time and can be made suitable for edible storage by this practice predates 19th century Britain and indeed written history, probably going back as long as humans have been using salt to preserve food.
