Kendal mint cake is a hard, brittle tablet made from sugar, syrup and boiled water flavored with peppermint oil. There is a white version, made with refined sugar, a brown one made with brown sugar, and a chocolate-coated variety. It is very sweet and refreshing, and for that reason has long been seen as a quick source of energy.
The most told story says that in 1869 confectioner Joseph Wiper of Kendal was trying to make transparent mint sweets, let the mixture overcook and ended up with an opaque, crystallized candy. Local accounts treat the episode as a legend: a sweet called mint cake was already sold in Kendal decades earlier.
Fame came with expeditions. A great-nephew of Wiper supplied the sweet to Ernest Shackleton’s Antarctic expedition from 1914 to 1917, and it was taken on the British Everest expeditions of 1922 and 1924. In 1953, Edmund Hillary and Tenzing Norgay carried Kendal mint cake on the first ascent to the summit of Everest. Since then the sweet has accompanied walkers and climbers in the Lake District mountains and elsewhere.
More than one traditional Kendal maker continues to produce it, and the sweet is sold in shops in the town and across the region.
