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 custard and add richness through their emulsifying fats and proteins.
- Cream
- Adds fat and richness, giving the frozen parfait a smooth, creamy texture.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the parfait soft rather than hard.
- Coarsely ground coffee
- Infuses coffee flavour into the custard as it steeps in the warm cream.
- Whipped cream
- Adds air and lightness, making the frozen parfait softer and more mousse-like.
The step that matters
Cooking the custard until thick. Egg yolks thicken as they heat, but overheating can scramble them into lumps. Stir over medium heat and stop once the custard coats a spoon.
