Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cranberry Tart
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cook cranberries with chopped apples, lemon juice, and sugar until soft.
Cool the mixture.
Assemble and bake
Line a flat dish with flaky crust.
Pour the cooled fruit mixture into the dish.
Twist some crust strips across the top and brush with sugar and water.
Bake in a 400°F (200°C) oven until golden.

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
- Cranberries
- Give tartness and a bright red colour that contrasts with the sweet filling.
- Apples
- Add body and soft texture to the filling as they cook down.
- Sugar
- Sweetens the tart and helps the crust brush turn golden as it bakes.
- Flaky pie crust
- Forms the base and top, becoming crisp and layered when baked.
The step that matters
Cool the fruit mixture before filling the crust. Hot filling melts the butter in the flaky crust before it can set, making the base soggy and the layers less flaky.
Swap the lemon
How well each one fits the dish's main ingredients (apple, sugar):
- Pearfits better
- Vanillafits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
