I have developed a pathetic and debilitating addiction to cold spicy mung bean noodles, the kind served at Szechuan restaurants. Since this dish doesn't seem terribly difficult to make at home - hot oil, garlic, scallions, right? - I'd like to prepare it myself and save money and precious, precious time. They are square sided and thick, and clearish, and gelatinous. But I can't find them at my local Chinese supermarket (on Clinton St., if you're interested). It seems like they ought to be in the refrigerator case next to the udon noodles, maybe. But they're not! Have you seen them anywhere?
