Fish and Chips

Fried fish and fried potatoes arrived in Britain by different routes. Fish fried in batter was introduced by Sephardic Jewish immigrants from Portugal and Spain, who prepared fish this way to be eaten cold on the Sabbath; the practice was well established in London by the early nineteenth century.

Fried potato slices came from a separate tradition in the north of England and, on the other side of the Channel, from Belgium and France. The two were combined into a single meal in the second half of the nineteenth century, with competing claims from London and from the industrial north for the first shop to sell them together.

What made it a mass food was infrastructure: steam trawlers landing large catches, and railways carrying fish inland packed in ice, quickly enough to reach industrial cities cheaply. Fish and chips became the working-class hot meal of industrial Britain, and it was considered important enough that it was never rationed during either world war.

The batter is the craft. Flour is mixed with a cold liquid — often beer or sparkling water — so that carbon dioxide and rapid temperature shock produce a light, bubbled, crisp shell rather than a heavy coating. The batter is used immediately; resting it flattens the result.

Cod and haddock are the traditional fish, with haddock preferred across much of the north and Scotland. Sustainability concerns have pushed shops toward alternatives such as pollock and coley in recent years.

Chips are thick-cut and fried twice: once at a lower temperature to cook the interior, then again hotter to crisp the outside. Beef dripping was the traditional frying fat and is still used by many shops for its flavour, though vegetable oil is now more common.

The standard dressing is salt and malt vinegar. Beyond that, regional preferences are strongly held: mushy peas made from marrowfat peas, curry sauce, gravy in parts of the north, and in Scotland a brown sauce and, in some shops, salt and vinegar replaced by a distinctive local chip sauce.

Wrapping in newspaper is remembered fondly but was prohibited on hygiene grounds, and shops now use food-grade paper printed to resemble it. The chip shop itself, open in the evening on an ordinary high street, remains a fixture of British life.
