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 ↓
Snow Souffle
Ingredients
Directions
Prepare the base
Beat the egg whites to a stiff froth.
Dissolve the gelatine in a little more than 1 pint of hot water.
Add the sugar and lemon juice to the gelatine mixture and let it cool.
Whip and set
Stir the beaten egg whites into the cooled mixture and beat until white and stiff.
Mould the mixture and pour soft custard around it before serving.

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
- Egg whites
- Whipped into foam, they trap air and give the soufflé its light, airy texture.
- Gelatine
- Sets the liquid mixture so it holds its shape when moulded.
- Sugar
- Adds sweetness and helps stabilise the whipped foam.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
The step that matters
Let the gelatine mixture cool before adding the egg whites. Gelatine begins to set as it cools, and if it is still hot the egg white foam will collapse and lose air. If it is too cold it may set in lumps before the whites are folded in. Cooling until it is just thickening keeps the foam stable.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
