Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Orange Custard
Ingredients
Directions
Prepare the oranges
Combine the orange pieces with 6-7 tablespoons of sugar.
Set the mixture aside for 2-3 hours.
Make the custard
Heat water in a kettle and place a tin pail with 1 quart of milk inside it.
Reserve ½ cup of milk to dissolve the cornstarch.
Add a pinch of salt to the milk in the pail and heat gently.
Beat the whole egg and 3 egg yolks together in a separate bowl.
Dissolve the cornstarch in the reserved milk and add it to the egg mixture.
Slowly add the egg mixture to the heated milk, stirring constantly until thickened.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the custard as they cook, giving it body and structure.
- Cornstarch
- Thickens the milk as it heats, giving the custard its smooth, firm texture.
- Milk
- Forms the liquid base of the custard and carries the flavour and body.
- Oranges
- Provide the fresh citrus flavour and aroma of the dish.
- Sugar
- Sweetens the oranges, and its contact with the fruit draws out juice.
The step that matters
Slowly add the egg mixture to the heated milk, stirring constantly. Eggs thicken when heated, but if they meet hot milk too quickly or stop being stirred, they can curdle or scramble. Adding the mixture slowly while stirring spreads the heat evenly so the custard thickens smoothly.
Swap the orange
How well each one fits the dish's main ingredients (milk, sugar, vanilla, egg):
- Figfits better
- Peachfits better
- Blueberryfits better
- Orangethe original
Fit is the average pairing score against milk, sugar, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes.
