Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Orange Gelatine
Ingredients
Directions
Make the gelatine
Dissolve the gelatine in boiling water.
When cool, add the orange and lemon juice, and sweeten to taste.
Strain the mixture carefully and let it partly harden.
Finish and set
Beat the egg whites to stiff froth and fold them into the gelatine mixture.
Place molds on ice until set.

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, sliceable gel as it cools.
- Orange juice
- Provides the main flavour and acidity, balancing the sugar.
- Lemon juice
- Adds sharp acidity that brightens the orange flavour.
- Egg whites
- Whipped to a foam, they lighten the texture of the set gelatine.
The step that matters
Fold the egg whites in gently. Whipped egg whites trap air in a fragile foam. Folding gently, rather than stirring, keeps the air bubbles so the set gelatine stays light. If the gelatine is too hot, it can deflate the foam; if it has partly set and is too stiff, the whites will not blend evenly.
Swap the orange
How well each one fits the dish's main ingredients (lemon, sugar, egg):
- Orangethe original
- Vanillafits about as well
- Limefits less well
- Raisinfits less well
Fit is the average pairing score against lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
