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 ↓
Apple Meringue Tart
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the tart shell
Preheat the oven to 400°F (200°C).
Line a tart dish with the short pastry and decorate the edge.
Peel, core, and slice the apples.
Make the apple filling
Boil the apples with the sugar and lemon rind until tender.
Pass the mixture through a fine sieve and mix in the egg yolks thoroughly.
Pour the apple mixture into the lined dish and bake for 20 to 30 minutes.
Top and brown
Whip the egg whites to stiff peaks and fold in the pink sugar.
Spread the meringue over the baked apples and return to the oven to brown slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Short pastry
- Forms the crisp case that holds the filling.
- Apples
- Provide the bulk and tender fruit base of the filling.
- Sugar
- Sweetens the apples and helps them soften into a smooth purée.
- Eggs
- Yolks enrich and bind the filling; whites whip into the meringue topping.
- Pink sugar
- Sweetens the meringue and helps it brown lightly in the oven.
The step that matters
Whipping the egg whites to stiff peaks. Egg whites hold air only when fully whipped and free of yolk or grease. Under-whipped or greasy whites produce a flat, weeping meringue that will not brown well. Sugar folded in gradually stabilises the foam.
Swap the apple
How well each one fits the dish's main ingredients (sugar, lemon, egg):
- Orangefits better
- Vanillafits better
- Limefits better
- Applethe original
Fit is the average pairing score against sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
