Dark soy sauce is a dark colored condiment that is sweeter, less salty, and thicker than other varieties. It is aged longer and combined with molasses resulting in a richer taste. Dark soy sauce is a crucial ingredient in dishes where the color is a key component such as Shanghai style red cooked dishes.
Uses: Dark soy sauce is excellent for braises due to its lower salt content and rich flavor. Try the classic braised pork belly dish Hong Shao Rou.
Regular soy sauce is not a good substitute for dark soy sauce.
