Nam phrik is a generic term that may refer to any of the types of more or less viscous, spicy, chili-based, hot sauces typical of Thai cuisine. Usual ingredients for nam phrik are fresh or dry chilies, garlic, shallots, lime juice and often some kind of fish or shrimp paste. In the traditional way of preparing the sauce, the ingredients are pounded together using a mortar and pestle, with either salt or fish sauce added to taste.
Nam phrik is normally served on small saucers placed by the main dish as a condiment or dip for bland preparations, such as raw or boiled greens, fish, poultry and meats. Depending on the type, the region and the family that prepares it, nam phrik may vary in texture from a liquid to a paste to an almost dry, granular, or powdery consistency.
Instead of khrueang kaeng or phrik kaeng, the words nam phrik can also be used to denote Thai curry pastes such as in nam phrik kaeng som for kaeng som or nam phrik kaeng phet for kaeng phet.
