Mark Evans said he discovered the lost recipe while he was researching his family history. The book was written in 1853 by his great-great grandmother, whose surname was Daniels and who was also a local herbalist in Llanelli in south Wales.
He now believes that the recipe was taken to Lynchburg, Tennessee, in the US, by her brother-in-law – John “Jack the lad” Daniels – where Jack Daniel’s whiskey is distilled.
Jack Daniel’s is one of the best-selling whiskeys in the world and its founder was from Wales. Evans said the recipe also matches ingredients found on the bottle.
“I’m pretty sure I’ve discovered the original recipe in great-great grannie’s book. I was doing some family research, looking at photographs and things, and I wanted to look at the family bible. At the bottom of the bookcase was this book,” he told the Llanelli Star.
