You must have been under a very remote rock not to have heard of Reggae Reggae Sauce – propelled to fame when its inventor, Levi Roots, sang ‘it tastes so nice, I had to name it twice’ to the Dragons’ Den judges. Reggae Reggae Sauce, which has around 70 Facebook groups dedicated to it, is arguably the most successful product to have come out of the TV series after Peter Jones and Richard Farleigh both invested.

Levi, who was nominated for a MOBO in 1998, says he should have marketed the sauce before. “We could’ve been rich a long time ago,” he told the BBC in August.
