Why it works: Lemon and orange 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 ↓
Cambridge Milk Punch
Ingredients
Directions
Make the punch base
In a pot, combine 2 quarts of new milk and the thinly pared rind of 1 lemon with ½ pound of sugar.
Slowly bring the mixture to a boil.
Remove the lemon rind.
Take the pot off the heat.
Add the eggs and spirits
Mix 2 well-whisked eggs with ½ pint of cold milk.
Strain the egg and milk mixture through a sieve.
Quickly stir the strained egg mixture into the pot.
Do not allow the milk to boil after adding the eggs.
Gradually add 1 pint of rum and ½ pint of brandy.
Optionally, include a Seville orange stuck with cloves for added flavour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the punch slightly and add richness when gently heated.
- Milk
- Forms the creamy body of the punch.
- Sugar
- Adds sweetness to balance the spirits.
- Rum
- Provides the main spirit flavour and aroma.
- Brandy
- Adds depth and warmth to the spirit blend.
The step that matters
Do not allow the milk to boil after adding the eggs. Once egg is added, high heat can scramble the proteins, leaving curds and a grainy texture. Keeping the mixture below boiling and stirring in the strained eggs quickly keeps it smooth.
Swap the orange
The recipe marks orange as optional. How well each one fits the dish's main ingredients (milk, lemon, sugar, egg, rum, brandy, clove):
- Vanillafits better
- Figfits about as well
- Orangethe original
- Applefits about as well
Fit is the average pairing score against milk, lemon, sugar, egg, rum, brandy, clove. Candidates are from the same food group and used in at least 100 recipes.
