Why it works: Orange and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 4,696 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Orange Mould
Ingredients
Directions
Prepare the base
Soak the gelatin in some of the milk.
Boil the remaining milk and add the gelatin, stirring until dissolved.
Boil the orange rind with the milk and remove it.
Cut the orange rind into strips and leave it in.
Make the custard
Add the sugar and the beaten yolks of the eggs, stirring until it thickens but do not let it boil.
Let the mixture cool slightly.
Fold in the stiffly beaten egg whites and the orange juice.
Mould and serve
Place sections of the 2 oranges (without seeds or white pith) in a wet mould and pour the mixture over them.
Once cold, turn out the mould.
Garnish with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and whites give the mousse its light, airy texture.
- Gelatine
- Sets the mixture so it holds its shape when turned out.
- Milk
- Forms the creamy base that the custard and gelatine are made in.
- Sweet oranges
- Supply the orange flavour and the fragrant oil from the rind.
- Sugar
- Sweetens the custard and balances the citrus.
- Orange juice
- Adds bright citrus acidity and extra orange flavour.
The step that matters
Thicken the custard without boiling it. Egg yolks scramble and curdle if they boil, so the mixture must only thicken gently. Gelatine also needs to be fully dissolved first, or it will set unevenly in the mousse.
Swap the orange
How well each one fits the dish's main ingredients (egg, milk, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
