Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange Custard
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Prepare a boiled custard and let it cool slightly.
Peel the oranges, removing all the white inner skin to avoid bitterness.
Slice the oranges into quarter-inch thick slices, then quarter the slices.
Mix the orange slices with the custard.
Bake
Pour the mixture into a baking dish or individual custard cups.
Beat the egg white until stiff and slightly sweeten it, then cover the custard with it.
Bake in a 400°F (200°C) oven until the top is browned.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Oranges
- Provide the main fruit flavour and juicy pieces that add moisture and tang to the custard.
- Egg white
- Beaten until stiff, it forms a light topping that sets and browns in the oven.
- Boiled custard
- Forms the creamy base that holds the orange pieces and sets as it bakes.
- Sugar
- Sweetens the beaten egg white topping and balances the oranges' acidity.
The step that matters
Removing the white inner skin from the oranges. The white pith is bitter, and it would carry that bitterness into the custard, so it should be fully removed before slicing.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
