When preparing glass noodles, ensure they are soaked in warm water until they are pliable but not overly soft. This helps them maintain their texture when added to the chicken broth. Additionally, to enhance the flavor of the sichuan peppercorns, lightly toast them in a dry pan before adding them to the broth. This will release their aromatic oils and provide a more robust flavor to the hot and sour soup.

How to Reheat Leftovers
- Gently reheat the glass noodles in a saucepan over medium heat. Add a splash of chicken broth to keep them from drying out and to maintain the soup's rich flavor.
- Alternatively, use a microwave-safe bowl to reheat the Suan La Fen. Cover the bowl with a microwave-safe lid or plate to trap the steam. Heat on medium power for 1-2 minutes, stirring halfway through to ensure even heating.
