Which Dragon's Den product became known as the Reggae Reggae Sauce brand?

The product presented by Levi Roots on Dragon's Den became known as Reggae Reggae Sauce.

The sauce is a Caribbean-style jerk barbecue sauce created from Roots's family recipe. Its branding draws on reggae music and Caribbean food culture, combining a distinctive name with Roots's performance persona and storytelling.

Roots pitched the product on Dragon's Den in 2007. The televised appearance helped attract public attention, and the sauce later became widely available through supermarkets and other retailers. It was subsequently marketed under the Levi Roots brand.

The answer is the product's original and widely recognised name. Levi Roots is the entrepreneur, not the sauce itself, while jerk sauce is a broader style rather than the specific brand name shown in the programme.
