There are few meals more suited to a hot summer day than a bowl of Chinese cold noodles. This suān là (酸辣), or “sour spicy” cold noodle recipe is at once refreshing and deeply satisfying. It’s also easy to throw together, and you can make it with dried spaghetti!
Cook the noodles according to package instructions until al dente or 1 minute past al dente stage. Pull the noodles out of the pot and into a colander. Rinse the noodles under cold water, and reserve some of the cooking liquid.
Meanwhile, in a serving bowl, add the light soy sauce, Shanghai rice vinegar, chili oil, sugar, Sichuan peppercorn powder, sesame oil, dark soy sauce, salt, MSG (if using), and garlic.
Add the noodles, noodle cooking water, scallion, and cucumber. Toss everything together and serve. If the noodles look dry, add a bit more of the cooking water.
