Why it works: Milk and orange 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
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the custard
Separate the eggs.
Beat the yolks in a bowl.
Mix the cornstarch with ½ cup cold milk to form a smooth paste.
Scald the remaining milk in a double boiler.
Add the cornstarch mixture to the egg yolks and pour the scalded milk over them, stirring well.
Return the mixture to the heat and cook for 5 minutes.
Set the mixture aside to cool.
Prepare the oranges
Cut the oranges into small pieces, removing seeds and tough membranes.
If the oranges are not sweet, sprinkle them with sugar.
Assemble and serve
When ready to serve, pour the custard over the oranges.
Beat the egg whites to stiff peaks, gradually adding the powdered sugar.
Pile the meringue on top of the oranges.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and enrich the custard, while whites whip into the meringue's airy structure.
- Milk
- Provides the liquid base that the custard thickens and sets into a smooth texture.
- Cornstarch (in the method)
- Starch thickens the custard as it heats and gelatinizes in the liquid.
- Powdered sugar
- Dissolves into the whipped egg whites, helping the meringue hold its stiff peaks.
- Oranges
- Add fresh acidity and aroma that balance the sweet custard and meringue.
The step that matters
Cooking the custard after adding the cornstarch and yolks. Starch must be heated enough to thicken the milk, but the egg yolks can curdle or scramble if the mixture gets too hot or is stirred too little. Stirring steadily in the double boiler keeps the custard smooth.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, milk):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
