Piri-piri, peri-peri or peli-peli is the name used in Portuguese and a number of African languages to describe the African bird's-eye chili. The variations in spelling derive from the various pronunciations of the word in parts of Africa, although "piri-piri" is the correct spelling in Portuguese.
In Portuguese cuisine, piri-piri is often used in preparing sauces and marinades for roast and grilled dishes, especially chicken and various fish.
Nando's, the Portuguese-themed chicken restaurant chain uses piri-piri in many of its dishes, and helped popularise them worldwide. The company, however, prefers the common South African spelling peri peri on its menus and branded sauces.
