Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Make the pastry
Make puff paste and give it six or seven turns, wetting the top with water or lemon juice before the last turn.
Roll out the paste to about ⅓ inch thick.
Shape and bake
Cut out circles with a 2-inch circular cutter.
Use a smaller cutter to press into the tops, sinking halfway through the crust.
Brush the tops with beaten egg, avoiding the edges.
Sprinkle sugar if filling with sweetmeats.
Bake until golden.
Hollow and fill
Remove the tops.
Cut out the centers without damaging the outsides.
Keep warm until ready to fill.
Cover with the tops.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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
- Puff paste
- Thin layers of butter and dough puff in the oven to form the hollow, flaky case.
- Beaten egg
- Coats the tops to give them a glossy, golden browning as they bake.
- Sugar
- Helps the tops brown and adds sweetness when filling with sweetmeats.
The step that matters
Sinking the inner cutter halfway through the crust. Cutting too deep can cut through the pastry, while too shallow a cut stops the centre from lifting cleanly; the cut sets the lid line so the case rises evenly and the lid sits neatly once hollowed.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
