Piri-piri peppers, also known as African bird's eye chili, are small, fiery chili peppers that originate from Africa. They are typically red or green and are known for their intense heat, ranging from 50,000 to 175,000 Scoville Heat Units. These peppers are often used in various cuisines, particularly in Portuguese and African dishes, to add spice and flavor. The name "piri-piri" comes from the Swahili word for pepper. Piri-piri peppers are commonly used to make sauces, marinades, and spice blends. They are a key ingredient in the popular piri-piri chicken dish, where the peppers are blended with garlic, lemon, and other spices to create a zesty flavor profile.
