Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Gelatine Snow
Ingredients
Directions
Make the gelatine base
Dissolve gelatine in 1 pint of cold water on the back of the stove.
Add sugar to the dissolved gelatine.
Pour 1 pint of warm water over the mixture and beat well.
Strain the juice of 2 lemons into the gelatine mixture.
Finish and decorate
Beat the whites of 2 eggs until stiff.
When the mixture is nearly cold, pour the beaten egg whites on top.
Arrange the yolks around the dish for decoration.

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 light, wobbly structure as it cools.
- Egg whites
- Whipped to stiff foam, they give the dessert its airy, snowy texture.
- Sugar
- Sweetens the dessert and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity that brightens the flavour and cuts the sweetness.
- Egg yolks
- Used for decoration around the dish, not as a structural part of the set.
The step that matters
Pouring the beaten egg whites onto the mixture. Egg whites must be beaten until stiff, and the mixture should be nearly cold before they are added. If the gelatine is still warm, the foam can deflate or sink instead of staying light on top as the base sets.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
