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
- Eggs
- Coagulate when gently heated, thickening the custard into a set, smooth texture.
- Sugar
- Sweetens the custard and helps balance the tartness of the currant juice.
- Currant juice
- Provides the main flavour and liquid base of the custard.
- Cream
- Adds richness and fat, giving the custard a softer, silkier mouthfeel.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the sweetness.
The step that matters
Thicken the custard in a water bath. Eggs set at a moderate temperature and curdle if overheated. Setting the jug in a pan of water keeps the heat gentle, so the custard thickens smoothly rather than turning grainy.
