What each ingredient does
- Raspberries
- Supply the fruit, flavour and bulk, and hold their shape when simmered gently.
- Sugar
- Sweetens the fruit and, as it dissolves and thickens, forms the syrup that preserves it.
The step that matters
Boil gently, being careful not to break the raspberries. Vigorous boiling bursts the fruit's skins and softens its cell walls, so the berries turn mushy and cloudy. A gentle simmer lets the fruit hold its shape while the sugar slowly draws water out and the syrup thickens.
