Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Orange Filling
Ingredients
Directions
Mix the ingredients in the order given.
Bring to a boil, stirring constantly.
Then cook in the top of a double boiler for 10 minutes to remove the raw taste of the flour.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Sugar
- Adds sweetness and helps thicken the filling as it cooks.
- Egg
- Thickens the filling as it heats and adds richness and structure.
- Flour
- Thickens the filling as it cooks; cooking it removes its raw taste.
- Orange rind
- Adds aromatic citrus oil and flavor to the filling.
- Orange juice
- Adds liquid, acidity and bright citrus flavor to the filling.
The step that matters
Cook long enough to cook out the flour. Flour must be heated fully to thicken properly and lose its raw, pasty taste. Stirring constantly while bringing it to a boil prevents scorching and lumps, since the egg can curdle or the starch can clump if heated unevenly.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, flour, butter, lemon):
- Raisinfits better
- Vanillafits better
- Figfits about as well
- Orangethe original
Fit is the average pairing score against sugar, egg, flour, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
