Dundee marmalade is a British orange marmalade associated with James Keiller’s commercial production in Dundee.
The marmalade is traditionally made from bitter Seville oranges, whose peel contributes a distinctive sharp flavour. James Keiller and his wife Janet are associated with the development of the Dundee business in the late eighteenth century. The brand later became known for marmalade containing visible strips of orange peel.
A popular story says that a large shipment of Seville oranges was bought cheaply after arriving in Dundee during a storm, but historians have questioned parts of that account. Marmalade is not simply any fruit jam: in British usage, it most often refers to a preserve made from citrus fruit, especially oranges. Dundee marmalade helped establish the product as a recognizable Scottish export.
