Steep the peels of 40 limes in 6 bottles of rum for 2 days.
Boil 3 cups of sugar in water and grate the nutmeg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Curdles with the acid and carries away tannins and harshness, leaving the punch clear and smooth.
- Lime juice
- Provides acidity that curdles the milk and brightens the sweet spirits.
- Sugar
- Sweetens the punch and balances the acidity and alcohol.
- Rum
- Forms the main spirit base and carries the flavour of the lime peel.
The step that matters
Adding the lime juice and hot milk while stirring. Milk curdles when acid is added, and the curds trap cloudiness and harsh compounds. Adding the acid gradually while stirring forms fine curds evenly, which settle out so the straining can produce a clear punch.
Swap the lime
How well each one fits the dish's main ingredients (rum, brandy, sugar, milk, nutmeg):
- Vanillafits better
- Figfits better
- Apricotfits better
- Limethe original
Fit is the average pairing score against rum, brandy, sugar, milk, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
