Sunshine citrus from damp Dundee?

How did Marmalade City come to be?

With days of sunshine less than three

and a climate controlled by the icy North Sea

Where did they get shredded peel and sugar sweet?

Invent breakfast jam, a national treat

When orange trees need sun, orange trees need heat

Yet a Dundee summer can often mean sleet

Well a Spanish ship was stranded they say

at the docks facing duties, unable to pay

A deal done in oranges, the anchor weighed

and citrus grove plans, spanned the banks of the Tay

So how did they do, years later? Let's see:

No match for Seville, but always to me

Dundee is our Orange Capital, by the slate grey sea

filling jars with more-ish Marmalade, for the nation's toast, and tea.
