An oil infused with Sichuan pepper, usually bought bottled, that carries the scent and numbing tingle of the pepper without the husks. It goes into dressings and dipping sauces, or a few drops over a dish at the end.
Made by infusing hot oil with 花椒 (Sichuan peppercorns). Delivers the tingling 麻 numbness central to Sichuan cuisine. Separate from 辣椒油 (chili oil), which provides the heat (辣).
