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 ↓
Lemon Sponge or Snow Pudding
Ingredients
Directions
Prepare the gelatine
Soak the gelatine in cold water for 5 minutes.
Dissolve the gelatine in boiling water, then add the grated rind and juice of the lemons and sugar.
Stir until the sugar is dissolved.
Set and whip
Strain the mixture and let it stand in a cool place until nearly set.
Add the beaten egg whites and beat the mixture until light and spongy.
Serve
Pour into a glass dish or mold and serve with a thin custard made from the egg yolks, or cream and sugar.

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, firm structure as it cools.
- Egg whites
- Beaten in, they trap air to make the pudding light and spongy.
- Sugar
- Sweetens the lemon mixture and balances its acidity.
- Lemon juice
- Adds sharp acidity and bright lemon flavour.
The step that matters
Let the mixture nearly set before adding the egg whites. Egg whites beaten into warm, runny gelatine collapse and deflate. Chilling until partly thickened gives the foam enough body to hold its air while the gelatine 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.
