To make the sauce, whisk together the miso paste, tahini, rice vinegar, toasted sesame oil, tamari, chili crisp, and maple syrup. Whisk until completely smooth. Taste and adjust as needed - more tamari for saltiness, maple for sweetness, chili for spice, vinegar for tanginess. Add water to thin, if needed.
2 tablespoons sesame oil or avocado oil, 2 tablespoons white miso paste, 2 tablespoons tahini, 2 tablespoons rice vinegar, 1 tablespoon toasted sesame oil, 1 tablespoon tamari, 1 teaspoon garlic chili crisp or chili flakes, ½ teaspoon maple syrup, 1-2 tablespoons hot water
