Sour Pickled Mustard is a traditional Asian fermented vegetable made from mustard greens. It has a tangy, savory, and slightly salty flavor, with a crisp texture and deep umami notes developed through natural fermentation.
Commonly used in stir-fries, soups, stews, and braised dishes, it adds a rich, appetizing sourness that enhances both meat and vegetarian recipes. It's a pantry staple in many Chinese, Thai, and Vietnamese households, loved for its bold flavor and versatility.
