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 ↓
Marlborough Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Peel, core, and grate the apples.
Make the filling
In a bowl, cream together the butter and sugar until light and fluffy.
Add the grated apples, eggs, lemon peel, and lemon juice to the mixture and stir well.
Pour the mixture into a prepared pie crust and bake until set and golden brown.

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 tartness that balances the sweetness.
- Butter
- Adds richness and a light, fluffy texture when creamed with sugar.
- Sugar
- Sweetens the filling and helps create a light texture when creamed with butter.
- Eggs
- Set during baking to bind the filling into a firm custard-like texture.
The step that matters
Bake until set and golden brown. Eggs set as they heat, so underbaking leaves the filling runny while overbaking can make it dry and rubbery. Look for a firm centre and an even golden top.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, egg, lemon):
- Vanillafits better
