What each ingredient does
- Cream
- Whipped to stiffness, it traps air and gives the frappe a light, creamy body.
- Sugar
- Caramelized portion adds deep flavour; the rest sweetens the cream and softens the ice crystals.
- Coffee
- Provides the main coffee flavour and liquid base that freezes into the frappe.
The step that matters
Freeze until it is barely pourable. Freezing stops once the mixture is slushy; if left too long it turns solid and icy. Sugar lowers the freezing point, so the mixture stays softer than plain coffee ice, and checking early keeps the texture smooth.
