What was the name of the sauce business presented by Levi Roots on Dragons' Den in 2007?

The sauce business presented by Levi Roots on Dragons' Den in 2007 was called Reggae Reggae Sauce.

Levi Roots, the stage name of Keith Valentine Graham, appeared on the programme with a Caribbean-style jerk barbecue sauce. The product's branding connected food with reggae music and Roots's Jamaican heritage, helping it stand out in a crowded condiment market.

He secured a £50,000 investment from Peter Jones and Richard Farleigh in exchange for a share of the business. The appearance became one of the programme's most famous entrepreneurial success stories, and the sauce developed into a wider Reggae Reggae product range.

The product name is sometimes shortened in casual discussion to “Reggae sauce,” but the established commercial name is Reggae Reggae Sauce. That exact wording is the canonical answer because it identifies the branded product rather than merely its style or ingredients.
