Shared aroma: beta-damascenone (apple, rose).

What each ingredient does
- Sugar
- Dissolves to form a clear, syrupy base that sets into a glossy, transparent icing.
- Strong brewed coffee
- Thins the boiled sugar to a pourable consistency and adds flavour.
The step that matters
Boiling the sugar until it dissolves. Sugar must fully dissolve before dilution; undissolved crystals can recrystallise and make the icing cloudy or grainy instead of transparent.
