Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brandy
- Extracts flavour from the citrus peel and gives the punch its alcoholic base.
- Sugar
- Sweetens the punch and balances the acidity of the citrus juice.
- Lemons
- Provide sharp acidity and aromatic oils from the peel and juice.
- Oranges
- Add sweetness, aroma and juice that softens the punch's flavour.
- Egg white
- Binds impurities in the sugar syrup so they can be skimmed off, clarifying it.
The step that matters
Clarify the sugar with the egg white. Heating the egg white with the sugar syrup lets it coagulate and trap impurities, which rise as scum to be skimmed. Skipping or rushing this leaves the punch cloudy and less clear.
