Cock-a-leekie soup is a Scottish soup dish consisting of leeks and peppered chicken stock, often thickened with rice, or sometimes barley. The original recipe added prunes during cooking, and traditionalists still garnish with a julienne of prunes.
While it is called "Scotland's National Soup", it probably originated as a chicken and onion soup in France. By the late 16th century, it had made its way to Scotland, where the onions were replaced with leeks. The first recipe was printed in 1598, though the name "cock-a-leekie" did not come into use until the 18th century.
The first known mention of this soup is from the Orchtertyre House Book (1737), an accounts book that recorded a dinner of 'cockie leekie fowlls in it'". The earliest recipe is from the Victorian era cookbook writer Isabella Beeton, and is thickened with "the fine part of oatmeal". Christian Isobel Johnstone (Meg Dods) said the soup "must be very thick of leeks and the first part of them must be boiled down into the soup until it becomes a lubricous compound".
