Why it works: Rum and sugar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,908 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Provides the sharp acidity that gives the punch its character.
- Rum
- Adds aroma and flavour that carries through the frozen mixture.
- Egg whites
- Whipped into a meringue, they add lightness and a smoother texture.
- Sugar
- Sweetens the punch and softens the texture of the frozen mixture.
- Lemon rind
- Contributes fragrant citrus oils that add aroma.
The step that matters
Mix in the rum and meringue once frozen. The mixture must be partly frozen so the added rum and meringue blend in evenly. If it is rock hard they will not combine, and if it is too soft the added ingredients will melt and thin it.
Swap the lemon
