Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 10,632 recipes mention both. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef marrow
- Melted marrow gives the filling richness and a soft, moist, fatty texture.
- Pastry cream
- Adds body and a smooth, custard-like texture to the filling.
- Sugar
- Sweetens the filling and helps the top brown during baking.
- 6 egg whites
- Whipped and folded in, they lighten the mixture and help it rise and set.
- Bitter-almond biscuits
- Crushed, they add a toasty, bitter almond aroma and some structure.
The step that matters
Fold the beaten egg whites into the mixture. Folding gently keeps the air beaten into the whites; stirring hard deflates them, so the pie bakes flat and dense instead of light.

Fit is the average pairing score against beef, cream, sugar, almond, biscuit, orange, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
