What each ingredient does
- Mocha coffee
- Provides the main coffee flavour and aroma to the syrup.
- Syrup
- Provides sweetness and body, and its concentration sets the final texture as it boils.
The step that matters
Boiling the coffee into the syrup to the pearl stage. As water evaporates during boiling, the sugar concentration rises, so the syrup thickens and firms as it cools. Stopping at the wrong point changes the texture, so the cook should watch the stage closely rather than relying on time alone.
