Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Egg proteins set gently when warmed, thickening the punch and giving it a creamy body.
New milk
Forms the creamy base of the punch and carries the other flavours.
Sugar
Sweetens the punch and balances the richness of the milk and the strong spirits.
Rum
Adds alcohol and a warm, aromatic flavour to the punch.
Brandy
Adds further alcohol and a fruity, warming depth to the punch.

The step that matters

Adding the eggs without boiling the milk. Egg proteins set and curdle when overheated, so the milk must stay below boiling after the egg mixture goes in. Boiling would make the punch grainy instead of smooth and creamy.
