Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon peel
- Gives the punch its lemon aroma and flavour as it steeps in the brandy.
- Brandy
- Provides the alcoholic base and carries the flavours of the lemon and spices.
- Boiling milk
- Curdles with the acidic lemon juice, and the solids settle out, leaving the punch clearer and smoother.
- Lemon juice
- Adds acidity that brightens the punch and causes the milk to curdle.
- Sugar
- Adds sweetness that balances the acidity of the lemon juice and the strength of the brandy.
The step that matters
Adding the boiling milk to the lemon mixture. Milk curdles when it meets acid, and the proteins clump and carry sediment down with them. The mixture must be given time to settle and then strained carefully, or the punch stays cloudy and the curds end up in the bottle.
Swap the lemon
How well each one fits the dish's main ingredients (brandy, sugar, milk):
