Nam chim kai is a traditional sweet chili sauce originating from Thailand. The sauce is usually made with a combination of fish sauce, garlic, chili flakes, lime juice, white wine vinegar, brown sugar, water, and rice wine. The ingredients are simmered in a saucepan until the sauce thickens and develops the consistency of runny syrup or honey.

Once prepared, nam chim kai can be used as an ingredient in many dishes, or more commonly as a dipping sauce for a variety of foods.
