What each ingredient does
- Lump sugar
- Provides sweetness and body, thickening the syrup as it boils down.
- Rum
- Adds aroma and flavor to the finished syrup.
The step that matters
Boil the sugar and water until thick. Sugar dissolves in water and concentrates as the liquid evaporates. Stopping too early leaves a thin syrup, while overboiling turns it sticky or caramelized, so judging the thickness matters.
