Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten until stiff, they add a light, airy foam that gives the punch a frothy texture.
- Lemons
- Their juice supplies the sharp acidity that balances the sweetness of the sugar and syrup.
- Sugar
- Dissolved into syrup and sweetened into the egg whites, it provides sweetness and helps stabilize the foam.
- Pineapples
- Their juice adds fruity flavour and body to the punch base.
- Champagne
- Added near serving, it adds sparkle and a light, dry effervescence.
- Jamaica rum
- Added near serving, it adds a strong, aromatic spirit flavour.
The step that matters
Beat the egg whites until stiff. Egg whites must be whipped to stiff peaks so they trap air and hold a foam. If they are under-whipped or greasy with fat, the foam collapses and the punch loses its light texture.
