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 ↓

Directions
Dissolve the gelatine and loaf sugar in 1 pint of milk for 2 to 3 hours.
Heat the mixture, but do not let it boil.
Stir the juice of 4 lemons into 1 pint of cold milk.
Mix the cold milk with the hot milk and pour into a mold at once.
Rub the sugar on the lemon rinds to extract the full flavor.

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 gel as it cools.
- Loaf sugar
- Adds sweetness and balances the sharpness of the lemon juice.
- Milk
- Forms the creamy liquid base that the gelatine sets.
- Lemon juice
- Adds bright acidity and lemon flavor to the set dessert.
The step that matters
Combining the cold lemon milk with the hot milk. Lemon juice is acidic and can curdle milk protein, so the lemon milk is kept cold and the mixture is never boiled. Pouring at once lets the gelatine set the mixture smoothly before it separates.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, milk):
- Vanillafits better
- Figfits better
- Peachfits better
- Lemonthe original
Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
