Leaving Jamaica at the age of six with his grandmother's secret ingredients tucked away in his suitcase, Keith ‘Levi Roots’ Graham had no idea that a few pimento seeds and his grandmother’s cooking skills would later reap remarkable success.

The Jamaican-British musician and entrepreneur now attributes much of the success with his United Kingdom best-selling Reggae Reggae Sauce to his grandmother, Miriam.

“I remember my grandmother had packed in my suitcase a bag of pimento seeds and she said ‘Tek that to the UK’. And we know pimento is a key ingredient and I took that to the UK and many years later, I was approached to go on BBC’s Dragons’ Den,” he said during a special culinary demonstration at the University of Technology (UTech), Jamaica ,on Thursday.
