1/16 oz. A thick, dark sauce made from fermented soybeans and wheat, essential to authentic Szechuan cuisine. This sweet bean sauce (tian mian jiang) provides the foundation for many classic Szechuan dishes including twice-cooked pork and Peking duck accompaniment. Its rich, slightly sweet flavor with fermented depth makes it indispensable in Northern Chinese cooking. The thick consistency allows it to coat ingredients evenly while adding complex umami notes.
