Hot and Sour Tofu Soup (Suan La Dofu Tang)
Forget the complicated Cantonese Hot and Sour Soup with a million ingredients! This is an authentic central Chinese version that will warm your heart and your palate without sending you on a hunt for ingredients.
Measure broth into a saucepan and bring to a simmer over medium-low heat.
Add tofu and green onions.
Slowly drizzle in the beaten egg to make long strands of egg.
Add mushrooms and cabbage and simmer for 5 minutes.
Remove from heat and season with chili sauce vinegar and soy sauce.
Stir in citric acid if using.
