Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rum
- Provides the alcoholic base that preserves the liquid and carries the flavour.
- Lump sugar
- Adds sweetness and body, balancing the sharpness of the lime juice.
- Lime juice
- Adds acidity and citrus aroma, giving the drink its tart character.
The step that matters
Dissolving the sugar in the lime juice. Sugar dissolves far more readily in an acidic liquid than in cold rum. Fully dissolving it first prevents grains from settling and ensures even sweetness throughout the mixture.
