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 Island
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the apples
Stew apples in minimal water until soft, about 20 minutes.
Strain the stewed apples through a sieve.
Sweeten the strained apples with sugar and add grated lemon.
Finish and serve
Beat egg whites to stiff peaks and gently fold into the apple mixture just before serving.
Serve with rich custard or imperial cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Form the main body of the dish and supply moisture and fruity flavour.
- Sugar
- Adds sweetness and balances the tartness of the apples and lemon.
- Lemon
- Adds acidity and bright aroma that lift the flavour of the apples.
- Egg whites
- Whipped to stiff peaks, they add lightness and an airy texture to the apple mixture.
The step that matters
Folding in the egg whites. Whipped egg whites hold air that gives lightness. Overmixing deflates the foam, and letting the mixture stand loses the volume, so fold gently and serve promptly.
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.
