In Dragons' Den, which company did entrepreneur Levi Roots pitch to the Dragons in 2007?

Levi Roots pitched Reggae Reggae Sauce to the Dragons on Dragons' Den in 2007.

Roots, whose real name is Keith Valentine Graham, presented his Caribbean-style jerk barbecue sauce during the fifth series. The pitch became one of the programme's most famous success stories because the product already had a strong personal identity, distinctive branding and a clear food-market opportunity.

The sauce was developed from Roots' family recipe and had been sold at Notting Hill Carnival before appearing on television. The Dragons' investment helped the brand move from a small-scale operation toward wider retail distribution. It later became associated with a broader range of Caribbean food products.

The pitch is sometimes remembered simply as “Levi Roots' sauce,” but the product's official brand name is Reggae Reggae Sauce. That exact name is the canonical answer to the question.
