Chiri in oiru / nam prik pao / Thai red chili paste

An oily paste similar to the XO sauce found in Chinese dishes, nam prik pao perks up any dish. It is spicy yet somehow sweet and mild all at the same time. The complexity largely comes from shami dried shrimp and kapi fermented shrimp paste. Nam prik pao also contains tamarind paste, which accounts for its subtle sweet-sour fruitiness.
