You can add a small amount of rock sugar or a pinch of salt when simmering chenpi. The choice depends on flavor preference and diet habits.
Flavor Differences
- Rock sugar: Softens bitterness and makes the drink rounder.
- Salt: Adds a clean, savory edge and keeps the profile light.

Diet Considerations
- Limiting sugar: Use no sugar or a tiny pinch of salt.
- Limiting salt: Use a small amount of sugar or no salt.
- Prefer clean flavor: Use neither.

In short, sugar suits a sweeter profile while salt suits a lighter, savory profile. Adjust to your taste and diet.
