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 Puffs
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the apple filling
Stew the apples in a saucepan with a little water and the butter until soft.
Let the apple mixture cool, then mix in sugar and lemon zest.
Assemble and bake
Roll out the puff pastry thinly and cut into squares.
Place a small amount of the apple mixture in the center of each square, taking care to use minimal juice.
Fold the corners of the pastry over the filling to form puffs.
Bake in a preheated oven at 400°F (200°C) for 15 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Puff pastry
- Forms the flaky, layered shell that puffs and browns in the oven.
- Apples
- Provide the soft, sweet filling that cooks down into the center of each puff.
- Butter
- Adds richness and helps soften the apples as they stew.
- Sugar
- Sweetens the filling and helps it caramelize slightly while baking.
The step that matters
Using minimal juice in the filling. Excess liquid from the stewed apples turns the pastry soggy and keeps it from puffing and crisping properly, since steam and moisture interfere with the layers setting in the oven.
