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 ↓
Gelatine Pudding
Ingredients
Directions
Make the gelatin
Pour cold water over the gelatine and add sugar.
Once soft, add boiling water, lemon juice, and beaten egg whites.
Beat well until light and pour into a glass dish.
Add the custard and set

Pour the custard over the gelatine mixture.
Chill until set and serve cold.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
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 wobbly, sliceable structure as it cools.
- Egg whites
- Beaten in to add lightness and a fluffy, airy texture.
- Egg yolks
- Thicken the milk into a custard and add richness.
- Milk
- Forms the base of the custard, adding creaminess and body.
- Sugar
- Adds sweetness and balances the lemon's acidity.
- Lemon juice
- Adds acidity and bright flavour that cuts the sweetness.
The step that matters
Adding the egg yolks to the hot milk. If the yolks are poured into very hot milk without being whisked in steadily, they can scramble into lumps instead of thickening smoothly. Whisking constantly and heating gently keeps the custard silky.
Swap the lemon

Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
