Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, wobbly jelly once it is dissolved and cooled.
- Egg whites
- Whipped into the mixture to give the jelly a light, foamy, snowy texture.
- Sugar
- Sweetens the jelly and adds body to the mixture.
- Lemon juice
- Adds acidity that brightens the sweetness and balances the flavour.
- Egg yolks
- Thicken the milk into a custard that gives richness and a smooth texture.
- Milk
- Forms the base of the custard, adding richness and creaminess.
The step that matters
Whisk in the egg yolks until thickened. Egg yolks thicken when heated gently. If the milk is too hot or the yolks are added too fast, they can scramble and curdle, so the custard should be heated slowly while whisking.
