Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Supply sharp acidity and citrus flavor, with rind oils adding aroma.
- Sugar
- Adds sweetness that balances the sourness of the citrus juice.
- China oranges
- Add sweet citrus juice and aromatic oils from the rinds.
- Brandy
- Adds warm, fruity alcohol flavor and aroma to the punch.
- Rum
- Adds rich, sweet alcohol flavor and depth to the punch.
- Egg whites (in the method)
- Whipped to froth, they lighten the texture and add a foamy body.
The step that matters
Add the frothy egg whites to the mixture. Whipped egg white foam traps air and gives lightness. Adding it gently keeps the bubbles from collapsing, so the punch stays frothy rather than flat.
