Why it works: Lime and rum work together. They rank in the top 11% of all ingredient pairs, and cooks put them together in 412 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Milk Punch
Ingredients
Directions
Prepare the infusion
Soak the lime peel in 1 bottle of rum for 24 hours in a covered container.
Squeeze the juice from the limes and set aside 1 quart for later use.
Combine and finish
Pour the soaked rum and lime peel into a large container.
Add 5 more bottles of rum, the lime juice, and 2.5 cups of sugar.
Boil 5 cups of milk and mix it with the other ingredients.
Let the mixture cool completely, then strain through double flannel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lime peel
- Soaked in rum for 24 hours, it releases aromatic oils that flavour the punch.
- Milk
- Boiled and stirred in, its proteins bind with the acid and clarify the punch as it cools and is strained.
- Lime juice
- Provides acidity that balances the sweetness and rum.
- White sugar
- Adds sweetness that balances the acidity of the lime juice and the strength of the rum.
- Rum
- Serves as the base spirit, carrying the flavours and preserving the punch.
The step that matters
Boiling the milk. Milk added hot to the acidic rum and lime mixture curdles its proteins, which then bind impurities so they can be removed. Letting the mixture cool completely before straining lets the curds settle, giving a clear result.
Swap the lime
How well each one fits the dish's main ingredients (rum, sugar, milk):
- Vanillafits better
- Pineapplefits better
- Bananafits better
- Limethe original
Fit is the average pairing score against rum, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
