Salty Soy Milk (Xian Dou Jiang)

A savoury breakfast revelation that turns humble soy milk into something extraordinary. Warm, freshly ground soy milk is curdled tableside with a splash of vinegar, transforming it into a silken, almost tofu-like broth studded with dried shrimp, pickled mustard greens, chili oil, sliced you tiao, and a scattering of scallions.
