Hot pepper sauce in Caribbean cuisine is as pervasive as ketchup in the US. The fiery flavouring is a staple of dining tables regionwide, the obligatory accompaniment for everything from rice and peas, to curries and stews. And as international palates continue to heat up to the potent taste, a growing number of brands are exported to North America, Europe and Australia, appearing on the shelves of major supermarket chains, from the US's Walmart, to the UK's Tesco, and Woolworths in Australia.
