Sweet Vinegar Pickled Black Beans

Why people make this preparation

This is one of the simplest and most beloved food-therapy staples in Cantonese households. You roast the black beans until their skins just begin to crack, then let sweet rice vinegar do the rest over two patient weeks. The result is a tangy, slightly chewy bite that generations of home cooks have relied on to support energy, blood quality, and digestion. The best part: once the jar is made, a daily spoonful requires almost no effort at all.
