Why it works: Apple and orange match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,230 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Apple Tart
Ingredients
Directions
Prepare the tart
Line a deep round pie tin with rich pie paste.
Fill the tin three-quarters full with sliced apples.
Dredge the apples with sugar.
Add a twist of crust around the edge.
Bake and finish
Bake until nearly done.
Spread a thin layer of orange marmalade on top.
In a bowl, mix milk, sugar, and egg yolks to make a custard.
Pour the custard over the tart.
Return the tart to the oven.
Bake until the custard is set.

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.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 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
- Apples
- Provide the bulk of the filling and tart flavour as they soften during baking.
- Egg yolks
- Set the custard so it firms into a sliceable layer over the fruit.
- Milk
- Forms the liquid base of the custard that bakes into a soft, creamy layer.
- Orange marmalade
- Adds a thin layer of sweetness and citrus aroma beneath the custard.
The step that matters
Baking until the custard is set. Egg yolks thicken as they heat, but overbaking can make the custard curdle or turn grainy and watery. Check for a set centre that jiggles only slightly.
Swap the orange
How well each one fits the dish's main ingredients (apple, sugar, milk, egg):
- Vanillafits better
- Figfits better
- Pearfits better
- Orangethe original
Fit is the average pairing score against apple, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
