Prepare Broth (0–5 min): In a large pot, heat sesame oil. Add garlic and ginger, sauté until fragrant. Pour in broth and bring to a gentle simmer.
Season Base (5–10 min): Stir in soy sauce and rice vinegar. Add mushrooms and carrots. Simmer until veggies begin to soften.
Add Protein (10–15 min): If using chicken, shrimp, or tofu, add now. Simmer gently until cooked through.
Cook Dumplings (15–25 min): Drop dumplings straight into the simmering broth. Cook until tender (follow package directions, usually 6–8 minutes).
Finish Soup (25–30 min): Stir in spinach or bok choy just before serving. Sprinkle with scallions and a dash of white pepper.
