The classic sauce for Asian-style or Chinese dumplings is made with a mixture of soy sauce, vinegar, and optional chili oil or hot sauce. For variations and instructions, check out my recipe for Dumpling and Potsticker Dipping Sauce. If you want a more rich creamy sauce, feel free to mix it up (I love these with Thai-style Peanut Sauce or an even simpler version using pantry staples, Creamy Peanut Dipping Sauce).
