Can I make hot and sour soup ahead of time?
Yes, prepare the broth and vegetables up to 2 days ahead and refrigerate separately. Add tofu and egg ribbons just before serving to keep them tender.
How do I get the silky egg ribbons?
Whisk 1-2 eggs in a bowl. Slowly drizzle into the simmering broth while stirring gently to create thin, delicate strands.
What can I substitute for soft tofu?
Use silken tofu for even softer texture, or substitute with soft-scrambled eggs, shrimp, or chicken. Firmer tofu will work but is less traditional.
How spicy is this soup?
The sriracha adds moderate heat; start with 1/2 tbsp and adjust to taste. White pepper provides background warmth without burn.
Can I thicken it more or less?
Mix cornstarch with cold water (slurry) and add gradually while simmering. Use less for brothier soup, more for gravy-like consistency.
