Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Orange Custards
Ingredients
Directions
Make the custard
Strain the juice of the oranges and sweeten it with pounded loaf sugar.
Heat the juice over low heat until hot, then remove any scum.
Allow the mixture to cool slightly, then stir in the beaten egg yolks and cream.
Cook over low heat, stirring constantly, until the mixture thickens.
Serve
Serve in cups.

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
- Egg yolks
- Thicken the custard as they set when gently heated, giving it a smooth, rich body.
- Cream
- Adds fat and richness, softening the texture of the set custard.
- Oranges
- Provide the juice that gives the custard its flavour and acidity.
- Pounded loaf sugar
- Sweetens the orange juice to balance its acidity.
The step that matters
Cook over low heat, stirring constantly, until the mixture thickens. Egg yolks set at gentle temperatures, but too much heat or too little stirring can scramble them into lumps. Constant stirring and low heat keep the custard smooth.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, cream):
- Vanillafits better
- Raisinfits better
- Strawberryfits better
- Orangethe original
Fit is the average pairing score against sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
