The Scotch Bonnet originated in the Caribbeans and is also their most popular hot pepper. The red scotch bonnet is great for growing in containers. This is a very hot pepper with a fruity and smoky flavor, which makes it perfect for Caribbean dishes and hot sauces. With a Scoville heat unit rating of 100,000 - 350,000, it is similar to the habanero in terms of heat, but stouter in appearance and sweeter in flavor.
