What each ingredient does
- Lump sugar
- Caramelizes when heated, forming the brown color that tints the finished liquid.
The step that matters
Stop at bright brown. Sugar caramelizes quickly, and once it passes bright brown it darkens into burnt, bitter flavors. Stirring steadily over gentle heat keeps the color even and controlled.
