What each ingredient does
- Egg white
- Whipped with sugar, it traps air and forms the light, fluffy foam structure.
- Powdered sugar
- Sweetens the foam and helps stabilise the whipped egg white.
- Mashed fruit
- Adds fruit flavour, sweetness, and moisture to the foam.
The step that matters
Beating the mixture for 15 minutes. Beating incorporates air into the egg white proteins, which unfold and form a network that holds bubbles. Under-beating leaves the foam dense and flat, while over-beating can make it dry and collapse.
