Marmalade. The story goes that marmalade was invented in 1700 when a storm-damaged Spanish ship, carrying Seville oranges, sought refuge in Dundee Harbour. The cargo was sold off cheaply to James Keiller, a down-on-his-luck local merchant, whose wife turned it into a preserve. True? No one really knows but we do know that the Keillers of Dundee, James and his mother Janet, were very important in the popularisation of marmalade and are thought to have been amongst the first commercial producers of marmalade, and certainly the most well known. For the first half of the 19th century their brand of Dundee Marmalade, available affordably to the working classes, was extremely popular and was the forerunner of today’s best-selling brands.
