Scotch bonnet, also known as scotty bons, bonney peppers, or Caribbean red peppers, is a variety of chili pepper named for its resemblance to a tam o' shanter hat. Also called ata rodo by Yoruba speakers of Nigeria, it is found mainly in the Caribbean islands; it is also found in Guyana (where it is called the ball-of-fire pepper), the Maldives Islands (where it is called githeyo mirus), Panama (where it is called aji chombo) and West Africa. Most Scotch bonnets have a heat rating of 100,000–350,000 Scoville units. For comparison, most jalapeño peppers have a heat rating of 2,500 to 8,000 on the Scoville scale. However, completely sweet varieties of Scotch bonnet are grown on some of the Caribbean islands, called cachucha peppers.
