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
- Slices of bread
- Forms the base and outer layers that hold the filling together.
- Lemon juice
- Adds acidity and tang that gives the dressing its sharp flavour.
- Sugar
- Sweetens the dressing and balances the sharpness of the lemon.
- Nut cream
- Adds richness and body to the dressing.
- Egg
- Egg proteins thicken the dressing as it heats, giving it a creamy set.
The step that matters
Pour the boiling mixture over the egg mixture while whipping. Adding hot liquid slowly while whisking gently warms the egg so it thickens smoothly instead of scrambling. Pouring too fast or without whisking can cook the egg into lumps.
Swap the lemon
How well each one fits the dish's main ingredients (bread, sugar, cream, egg):
- Vanillafits better
- Raspberryfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against bread, sugar, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
