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 Custard
Ingredients
Directions
Prepare
Soak the gelatin in cold water for about 10 minutes.
Simmer the milk with the thin rind of one orange for 10 minutes, then remove the rind.
Peel the oranges, divide them into segments, and sweeten with caster sugar.
Make the custard
Beat the egg yolks well and stir them into the milk over low heat until it thickens, without boiling.
Add the sugar and gelatin, stirring until dissolved.
Whip the egg whites to stiff peaks.
Allow the custard to cool, then stir in the whipped egg whites just before it sets.
Pour the mixture into a wetted mold with a pipe in the center.
Serve
Once the custard has set, turn it out into a glass dish and fill the center with the orange pieces before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the milk into a custard, and whipped whites lighten the set mixture.
- Gelatine
- Sets the custard so it holds its shape when turned out of the mold.
- Milk
- Forms the creamy base of the custard and carries the orange flavour from the rind.
- Caster sugar
- Sweetens the custard and the orange segments.
The step that matters
Thickening the yolks over low heat without boiling. Egg yolks begin to scramble and curdle when they get too hot, so gentle low heat is needed to thicken the milk smoothly. Boiling can leave the custard grainy and prevent it from thickening evenly.
Swap the orange
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
