She said marmalade was made in huge quantities there in Dundee's heyday.
Definitely! Supposedly invented by one James Keillor of Dundee (as in ... Keillor's Marmalade

). The story goes a Spanish ship went down in the Firth of Tay, and these boxes of thick-skinned and bitter fruit were washed ashore. Completely inedible, so his thrifty wife boiled it and added sugar - and they made their fortune.
And you can still
get/make Dundee marmalade - gorgeous stuff!
But as far as I know, there's only one company still making "proper marmalade" in the area ... and they're up the road in Arbroath.
Aye - and it's Dundonians.
