Description Legend has it that in the 18th century a Spanish ship took refuge from a ranging storm in the sheltered harbour of Dundee, Scotland. Its cargo included Seville oranges which were purchased on speculation by a Dundee grocer called James Keiller. It was Mrs. Keiller who saw the potential of these bitter Spanish oranges. She boiled the oranges with sugar and the resulting product was the delicious preserve now known as the Dundee Orange Marmalade. Today the Keiller name carries forth the tradition of using only the finest ingredients in their range of premium marmalades and preserves.
