Why it works: Lemon and sugar 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 Jelly
Ingredients
Directions
Make the jelly
Soak the gelatine in cold water until soft.
Add boiling water and stir until dissolved.
Mix in lemon juice, lemon rind, and sugar to taste.
Set and serve
Strain through a fine cloth and set in a cold place.
Once stiff, beat in the egg whites and pour into molds.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar 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 firm, wobbly jelly structure as it cools.
- Egg whites
- Whipped into the partly set jelly, they trap air to give a light, snowy texture.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sugar.
- Lemon rind
- Adds aromatic oils that give a stronger lemon fragrance.
- Sugar
- Sweetens the jelly and balances the sharpness of the lemon.
The step that matters
Beat in the egg whites once the jelly is stiff. Egg white foam holds its air best when the gelatine has partly set, so the jelly is thick enough to support bubbles. If it is still runny, the whites deflate and the snowy texture is lost. If it is too firm, the whites stay in lumps instead of blending.
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.
