What each ingredient does
- Sugar
- Provides sweetness and body, and thickens the juice into a syrup as it dissolves and reduces.
- Fresh juice from lemons or oranges
- Supplies the main flavor and acidity that gives the syrup its bright taste.
The step that matters
Skimming off the foam while boiling. Foam forms as impurities and bits of pulp rise to the surface during boiling. Removing it keeps the syrup clear and prevents off flavors and cloudiness.
