In a bowl, combine all sauce ingredients (soy sauce, vinegar, sugar, hot water, sesame oil, garlic, sesame seeds, and optional chili crisp).

Mix thoroughly for 30 seconds until the sugar completely dissolves. Taste and adjust to your preference.

Cook your dumplings, potstickers, or wontons according to package instructions until golden brown and heated through.

Serve immediately by dipping your perfectly cooked dumplings in the freshly made sauce and enjoy!
