Which product won investment on Dragons' Den after being pitched by entrepreneur Levi Roots?

Reggae Reggae Sauce won investment on Dragons' Den after being pitched by entrepreneur Levi Roots.

Levi Roots, whose real name is Keith Valentine Graham, presented his Caribbean-style barbecue sauce on the programme. The pitch helped turn a product associated with his music and food background into a widely recognised commercial brand.

The sauce is based on a family recipe and uses Caribbean-inspired flavours. Roots appeared on Dragons' Den in 2007, where the presentation attracted investment and substantial public attention. The resulting brand expanded beyond its original sauce into a wider range of food products and became closely associated with Roots's stage name.

The answer is the product's exact brand name, not “jerk sauce,” which is a broader description of Caribbean cooking. Reggae Reggae Sauce is the specific product title connected with Levi Roots's successful Dragons' Den pitch.
