Peri-Peri is a hot or mildly hot seasoning, sometimes a prepared sauce, that is of Portugese origin. In South Africa, Peri-Peri seasoning is virtually a staple. It is much more than a mere hot sauce. Although not well-known in North America, it adds great flavor to many foods, especially chicken and fish. It is available in specialty stores and also from internet-based companies that sell South African products.
