Why it works: Sugar and rum 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 ↓
Punch a LA Bomaine
Ingredients
Directions
Make the punch base
Add the sugar to the boiling water and pour it over the thinly pared rind of the lemons and the strained juice.
Let the mixture stand covered until cold.
Freeze
Strain the mixture and freeze it.
When about half frozen, add the rum and finish freezing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Loaf sugar
- Dissolves into the hot water to sweeten the lemon juice and balance its acidity.
- Lemon juice
- Provides the sharp acidity and bright flavour that defines the punch.
- Lemon rind
- Adds aromatic lemon oils to the base as it steeps in the sweet liquid.
- Jamaica rum
- Adds spirit flavour and, because alcohol does not freeze solid, keeps the punch softer when frozen.
The step that matters
Adding the rum at half frozen. Alcohol lowers the freezing point, so rum added to a fully frozen mixture will not blend in evenly. Adding it when the mixture is about half frozen lets it mix through the slush and keeps the texture smooth and scoopable.
Swap the lemon

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