Dan dan noodles are traditionally made with round, thin to medium-thin Chinese wheat noodles – not rice noodles. Most Asian markets will carry semi-fresh wheat noodles in the refrigerated section; however, they won’t be labeled as “dan dan noodles,” so be sure to check the ingredients. If an Asian grocery store isn’t nearby, dry, round, thin Asian-style wheat noodles will also work. In a pinch, you can try using noodles like spaghetti or linguine, but the texture and taste will be slightly different from the traditional dish.
