Served as an appetizer, palate freshener, or a side dish, pào cài is a Sichuan-style pickle made with various vegetables, mostly Chinese cabbage, carrots, mustard stems, long beans, daikon radish, turnips, cucumbers, ginger, and hot peppers.
In Sichuanese cuisine, these crunchy, tangy pickles are always on hand, and almost every family keeps a large clay pot in their kitchen, filled with a variety of seasonal vegetables in a simple water and vinegar brine seasoned with salt, sugar, and Sichuan peppercorns.
