Cold-Tossed Rice Noodles

凉米线 is a hot-season staple across Yunnan, particularly Kunming and Dali, where summer afternoons routinely hit 30°C and noodle stalls switch from broth-based to cold-tossed formats from May through September. The cold preparation is older than the modern restaurant scene — household summer food going back generations. Each region tunes the sauce: Kunming heavier on chili oil, Dali leans toward fermented bean and pickled greens.

凉米线 — Yunnan summer staple from May to September, when Kunming and Dali afternoons hit 30°C. The noodle has to be 干浆 fermented-batter rice noodle; non-fermented versions go gummy when cooled. Sauce built thick on purpose — cold liquid won't bind otherwise.

Rice noodles cooled to room temperature, tossed in a small bowl with red chili oil, dark vinegar, soy, sesame paste, garlic water, crushed peanut, cilantro, sometimes pickled radish. Eaten with chopsticks pulling noodles up and out — the sauce should cling, not pool. Sour-spicy hits first, sesame and peanut close. A summer dish; rice noodles cold are slipperier than wheat.

The noodle has to be the right rice noodle — Yunnan 酸浆 (fermented-batter) rice noodle, not Vietnamese-style. Fermentation gives the noodle a slightly sour edge and a firmer bite that holds up cold; non-fermented noodles go gummy when cooled. The sauce is built thick on purpose — cold liquid doesn't bind to noodle the way hot broth does, so the dressing must be paste-like to coat at all.
