These quick Chinese sesame noodles are rich, nutty, savory, and ready in about 10 minutes. A creamy sesame-peanut sauce clings to hot wheat noodles, with scallions and chili oil adding freshness and heat.
Bring a pot of water to a boil and cook the fresh wheat noodles according to the package directions, just until tender and springy.
While the noodles cook, whisk the sesame paste, peanut butter, light soy sauce, rice vinegar, vegetable oil, sugar, and hot water in a bowl until smooth and pourable. Add the water gradually so the sauce emulsifies instead of turning lumpy.
Drain the noodles well, then immediately toss them with the sesame sauce while they are still hot. Add the chopped scallion and finish with chili oil if you want a spicy kick. Serve warm or at room temperature.
Chinese sesame paste gives the deepest roasted flavor, but tahini can work in a pinch; add a little extra peanut butter if using tahini. If the sauce thickens as it sits, loosen it with 1-2 tbsp hot noodle water. For make-ahead noodles, store the sauce and noodles separately and toss just before serving.
