Why it works: Milk and lemon 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 ↓

Pour ½ cup of boiling water over the soaked gelatine.
Make the jelly
Add ½ pound of lump sugar and stir until dissolved.
Mix in 1 pint of cold milk and 2 well-beaten eggs.
Stir in the juice of 3 lemons.
Pour the mixture into a mold and set it to chill.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid mixture into a firm, wobbly jelly as it cools.
- Eggs
- Add richness and body, helping the mixture hold a creamy texture.
- Lemon juice
- Adds acidity that brightens the sweet milk mixture and balances its flavour.
- Milk
- Provides the creamy base and moisture for the jelly.
The step that matters
Pour the boiling water over the soaked gelatine. Gelatine must be fully dissolved to set evenly. Gentle, complete melting prevents lumps and weak patches in the finished jelly.

How well each one fits the dish's main ingredients (sugar, milk, egg):
