The dance notes give a story about Scots Marmalade:
Its invention is accredited by long tradition to Janet Keiller, nee Pierson, a young woman of humble birth whose marriage to James Keiller April 1, 1700 is recorded in the Dundee Register. They owned a small business in the city. One morning a ship from Spain, long buffeted by easterly gales, reached Tayside and deposited a cargo of oranges. Among those gathered at the dock was James Keiller. The oranges were going cheap, and James bought a considerable quantity, rashly as it seemed, for owing to their bitter taste he was unable to sell them. His thrifty and resourceful wife supplied the answer. We may assume that she was already skilled in the making of jams and jellies, but little could she have dreamed, as she stood over the kitchen fire boiling and testing, that the result of her experimenting would achieve world-wide renown.
We are also told this story. Once during her girlhood years at the Court of France, Mary, Queen of Scots, became ill and her French doctor prescribed orange jelly. Fresh oranges were picked and the jelly was made immediately. But no one else could have the orange jelly. It was strictly made for “Marie malade” and that’s what gave us the name “Marmalade”.
