Early in the sixteenth century, chiles were transferred from Portuguese Brazil to their colony of Angola. These small, piquin-like chiles (which were probably Brazilian malaguetas) were called piri-piri (pepper-pepper) and became an integral part of the local cuisine. The sauce made from them was transferred back to Portugual, where it is a staple on dining tables--served with seafood, soups, and stews. Since the piri-piri chiles are not usually available, use chiles de árbol, cayenne chiles, chile piquins, or chiltepíns. Note: This recipe requires advance preparation.
The word capon translates as "castrated" but in this case merely means seedless. Yes, dried chiles such as anchos and pasillas can be stuffed, but they must be softened in hot water first. They have an entirely different flavor than their greener, more vegetable-like versions.
