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 ↓
Snow Custard
Ingredients
Directions
Prepare the gelatine
Soak the gelatine in a teacup of cold water for 1 hour.
Add 1 pint of boiling water to the soaked gelatine.
Stir until the gelatine is dissolved.
Mix in two-thirds of the sugar and the lemon juice.
Make the meringue
Beat the egg whites until stiff.
Gradually whip in the gelatine mixture, spoonful by spoonful, for 1 hour.
Pour the mixture into a mold that has been wet with cold water.
Refrigerate until set, about 4 to 5 hours.
Make the custard
Combine the milk, egg yolks, and remaining sugar in a saucepan.
Flavor with vanilla.
Cook until thickened.
Serve
Turn the set meringue onto a serving dish.
Pour the custard around the base.

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 mixture into a firm, sliceable structure as it cools.
- Eggs
- Whites whipped to stiff foam give the snow its light, airy texture; yolks enrich the custard.
- Milk
- Forms the base of the custard, adding richness and body.
- Sugar
- Sweetens both the snow and the custard and helps give the custard a smooth body.
- Lemon juice
- Adds acidity that brightens the sweetness of the dish.
The step that matters
Gradually whip in the gelatine mixture. Gelatine must be added slowly to the whites while it is still liquid but not hot, so it blends in without deflating the foam or setting in lumps before the whites are fully incorporated.
Swap the lemon
How well each one fits the dish's main ingredients (egg, milk, sugar):
- Vanillafits better
- Figfits about as well
- Raisinfits about as well
- Lemonthe original
Fit is the average pairing score against egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
