Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture as they set with heat, giving a rich, smooth body.
- Sugar
- Sweetens the punch and softens the texture of the frozen mixture.
- Cream
- Adds fat for a rich, smooth mouthfeel.
- Milk
- Forms the liquid base that the yolks thicken.
- Rum
- Adds flavour and, as alcohol, keeps the frozen mixture softer.
The step that matters
Heating the egg mixture to boiling point. Egg yolks thicken as they heat, but if the mixture overheats it can curdle or turn grainy. Stirring constantly and heating gently keeps the custard smooth before it is cooled.
