175,000 Scovilles. Also sometimes known as Piri Piri, the African Bird’s Eye is a small chile, growing to only about 1 inch, but they pack a lot of punch. They mature to red or purple, and have a tapered shape, with a blunt point. Historically found in the African wild, it has recently been grown commercially in some parts of Africa, often to be used as pepper extract or as organic pest control. The African Bird’s Eye is commonly used in soups, stews, hot sauces and chicken dishes, but the flavor is less interesting than other popular peppers. It is a close relative of the Tabasco pepper.
