There's no single fixed recipe — locals argue the dish is defined less by the noodles than by the sauce, often assembled from a dozen-plus separate condiments in the bowl.
Thin wheat noodles are boiled briefly and tossed in a bowl pre-loaded with chili oil, Sichuan peppercorn, preserved vegetables, garlic, and scallion, often with pickled long beans or minced pork.
