What is the secret ingredient in Yellowman?

Sweets are sold at fairs and markets the world over, but in north Antrim, one has a special place in the heart of locals.

Yellowman, a honeycombed sticky toffee, is near-exclusively tied to the Ould Lammas Fair.

For decades the Devlin, McKeown and Agnew families from Ballymena were central to yellowman production.

John Devlin believes his grandfather, Joe Devlin, is responsible for naming the confectionary and bringing it to the fair in the early 1900s.

BBC News tried to get the secret to the treat back in 1977 while speaking with John's aunt Eleanor but to no avail.
