Why it works: Lemon and orange 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 Charlotte
Ingredients
Directions
Make the jelly
Soak the gelatine in cold water until soft.
Pour the boiling water over the softened gelatine.
Add sugar and lemon juice, then strain the mixture.
Stir in the orange juice and pulp along with a little grated orange rind.
Cool the mixture in a pan of ice water.
Whip and mold
Whip the egg whites until stiff.
When the orange jelly begins to thicken, beat it until light, gradually adding the beaten egg whites until stiff enough to drop.
Mold the mixture and serve with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the orange mixture so it holds its shape when molded.
- Eggs
- Whites whipped into the jelly add lightness and an airy, foamy texture.
- Orange juice
- Provides the main orange flavour and liquid for the jelly.
- Sugar
- Sweetens the jelly and balances the lemon's acidity.
- Lemon juice
- Adds acidity that brightens the sweetness and orange flavour.
The step that matters
Beating the jelly as it thickens. If the jelly is beaten after it has set firm, the egg whites cannot be folded in evenly, and the mixture stays dense. Beat it only once it begins to thicken, and add the whites gradually so they stay airy and hold their shape.
Swap the orange
How well each one fits the dish's main ingredients (sugar, lemon, egg, cream):
- Vanillafits better
- Raspberryfits about as well
- Orangethe original
- Raisinfits less well
Fit is the average pairing score against sugar, lemon, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
