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 ↓
To Prepare Apples or Pears for Tartlets
Ingredients
Directions
Prepare the fruit
Peel, core, and quarter the apples or pears.
Boil the fruit in water until tender.
Drain most of the water and reduce the fruit to a pulp by squeezing or passing it through a sieve.
Make the filling
Remove the yellow rind from a lemon and mix it with some loaf sugar.
Combine the lemon sugar with the fruit pulp, adding more sugar and lemon juice to taste.
Simmer the mixture in a well-tinned saucepan for a few minutes, stirring occasionally.
Let it cool before using.

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 or pears
- Provides the bulk of the filling and its fruity flavour once cooked to a pulp.
- Loaf sugar
- Adds sweetness and, once simmered, thickens the pulp into a spreadable filling.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
The step that matters
Reduce the fruit to a pulp and simmer it. Fruit must be fully tender and well drained so the pulp is not watery. Simmering in a well-tinned saucepan with frequent stirring evaporates excess liquid and keeps the sugar from scorching on the bottom.
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.
