London, Nov 3 (ANI): Historians claim to have found the 150-year-old recipe of Lea and Perrins' Worcestershire sauce.
Although the original recipe has been kept top secret, a former accountant at the company had found the notes dating from the mid 1800s in a rubbish container by the firm's site.
Brian Keogh, who died in 2006, had found the original recipe in two leather-bound folios written in sepia ink.
The recipe was written in two different styles of handwriting, which analysts believe was due to the fact that no one knew the entire recipe.
Keogh's daughter Bonnie Clifford is now working with the museum to test the papers.
The classic recipe is believed to contain ingredients including cloves, vinegar, pickles and tamoraide.
"There has always been a lot of secrecy surrounding the recipes and pride that it is made locally," the Telegraph quoted Worcester City Museums collections officer David Nash as saying.
"Not even the staff knew the whole recipe, only parts of it, which would account for the different handwriting, and some of the ingredients were written in code.
"Even with all the ingredients there is no guarantee you would be able to make the sauce as what makes it distinctive is the way it is made, which is still a secret."
"It would be significant to the people of Worcester and maybe even attract national interest if they are proved to be genuine," he added. (ANI)
