Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White loaf sugar
Dissolves into the water to form the syrup that sweetens the punch.
Lemon juice
Adds acidity that balances the sweetness and brightens the flavour of the punch.
Jamaica rum
Provides the spirit base and the main aroma and flavour of the punch.

The step that matters

Add the rum only once the syrup is near cool. Alcohol evaporates readily when hot, so adding rum to boiling syrup would drive off much of its aroma and strength. Waiting lets the spirit stay in the punch.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, rum):

  1. Vanillafits better
  2. Pineapplefits better
  3. Bananafits better
  4. Lemonthe original

Fit is the average pairing score against sugar, rum. Candidates are from the same food group and used in at least 100 recipes.
