Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks and whites thicken the mixture as they cook gently, giving it a set, custard-like body.
- Butter
- Adds fat that melts smoothly and gives the mixture a rich, silky mouthfeel.
- Sugar
- Sweetens the mixture and helps it stay smooth and glossy as it cooks.
- Lemon juice
- Adds acidity that gives the mixture its bright, sharp lemon flavour.
The step that matters
Cook over low heat without boiling. Egg proteins set gently with heat, but boiling can curdle the eggs and leave the mixture grainy. Gentle heat and steady stirring keep it smooth as it thickens.
Swap the lemon
