Why it works: Cream and sugar 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
- Cream
- Provides fat and richness, giving the posset its smooth, silky body.
- Egg yolks
- Thicken the mixture as they heat, setting it into a soft, custard-like texture.
- Egg whites
- Add extra protein to help the mixture set and hold its structure.
- Ale
- Adds liquid and a malty, slightly bitter flavour that cuts through the richness.
- Sugar
- Sweetens the posset and balances the bitterness of the ale.
The step that matters
Remove from heat when thickened, just before boiling. Egg proteins set as they heat, but if the mixture boils it can curdle and turn grainy. Stopping just before boiling keeps it smooth and thickened.
