Edinburgh rock was first made in the 19th century by a man named Alexander Ferguson, who became known as 'Sweetie Sandy'.
He learned the confectionery trade in Glasgow, and then moved to Edinburgh to set up his own business.
The success of Edinburgh rock was such that he was able to retire back to Doune a very rich man.
[1] In the early 20th century, the rock was produced and sold at 1 Melbourne Place (now demolished, but previously the corner of George IV Bridge with the Lawnmarket).
He tried a piece of the desiccated results, found it to be delicious, and so Edinburgh rock was born.
