Vietnamese Caramel Sauce (Nước Màu)

This caramel sauce starts by melting sugar in a pan over medium heat, stirring constantly to prevent burning. The sugar transitions from granular to melted and darkens slowly to a deep brown, occasionally smoking to indicate reaching the caramelization point. Once the sugar is very dark but not burned, the heat is turned off and warm water is added immediately to halt further cooking and dissolve the caramelized sugar into a sauce. The amount of water can be adjusted for thickness; using less yields a syrupier sauce.

Nước Màu provides color and a balanced caramel sweetness that accentuates savory dishes such as braised meats. Its liquid form is designed for easy incorporation into simmered recipes. The timing and watchfulness during caramelization are important to avoid bitter burnt flavors.

The recipe notes that halving the water yields a thicker sauce, and larger batches can be scaled proportionally. The watery consistency described is suitable for the intended use in dishes like Thịt Kho. Adding the sauce late in cooking gives dishes characteristic deep brown hues and distinctive flavor.
