A LITTLE SOMETHING TO READ

Story & history

Two sour notes in Chongqing’s sour-and-hot vermicelli

In one traditional Chongqing method, sour-and-hot vermicelli gets two layers of sourness: aged vinegar gives a sharp edge, while pickled radish adds fermented tang. Sweet-potato vermicelli carries these with chili oil, Sichuan pepper, aromatics and toppings. Cooks vary the ratios and heat control, so “sour and hot” names a pairing rather than one fixed recipe. That balance is part of what gives local shops room for their own bowl.
