Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
Prepare
Remove the rind from the Seville orange without grating it.
Place the rind in a bowl and squeeze in the juice of the two oranges and one lemon.
Add the syrup and water, then mix and strain the mixture.
Freeze and finish
Freeze the mixture until solid, then stir it well with a spoon.
While mixing, add rum to taste, then return the mixture to the freezing pot.
Transfer the mixture to molds and freeze until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Seville orange rind
- Supplies aromatic citrus oils that flavour the punch.
- Oranges
- Provide juice for sweet-sharp citrus flavour and liquid volume.
- Lemon
- Adds acidity that brightens the flavour and balances the sweetness.
- Syrup
- Adds sweetness and lowers the freezing point so the punch stays softer.
- Rum
- Alcohol lowers the freezing point, keeping the frozen punch softer and scoopable.
The step that matters
Stirring the frozen mixture. Stirring after the mixture is solid breaks up ice crystals as it thaws slightly and refreezes. This gives a smoother, more even texture instead of a hard, icy block.

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