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 ↓
Princess Pudding
Ingredients
Directions
Make the custard
In a basin, beat the egg yolks lightly.
Boil the milk and pour it over the yolks.
Add the gelatin and return the mixture to the saucepan.
Cook gently without boiling until thick and the gelatin is dissolved.
Stir in the sugar, then pour into a large basin.
Add the orange juice, lemon juice, and cochineal.
Set and serve
Beat the egg whites to stiff peaks and gently fold into the mixture when it is nearly cold.
Pour into a mold and refrigerate until set.
Once set, turn out and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they cook gently, and add richness and colour to the base.
- Gelatin
- Sets the liquid mixture so the pudding holds its shape when turned out.
- Egg whites
- Whipped to stiff peaks, they lighten the set pudding with an airy, fluffy texture.
- Milk
- Forms the creamy base that the egg yolks thicken into a custard.
- Sugar
- Adds sweetness that balances the citrus juices.
- Orange juice or fruit puree
- Adds fruit flavour and liquid to the set pudding.
The step that matters
Cook gently without boiling. Egg yolks thicken from gentle heat; boiling can curdle them into grainy lumps, so the custard must stay below a simmer until it coats a spoon.
Swap the orange
How well each one fits the dish's main ingredients (milk, egg, gelatin, sugar, lemon):
- Vanillafits better
- Orangethe original
- Figfits about as well
- Raspberryfits about as well
Fit is the average pairing score against milk, egg, gelatin, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
