Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Flaky Pastry
Ingredients
Directions
Make the dough
Divide the butter or lard into four equal portions.
Rub one portion into the flour and salt as for short pastry.
Mix into a stiff but smooth paste with cold water.
Laminate the pastry
Turn out onto a floured board and roll into a long strip.
Place one of the three remaining portions of butter or lard in small lumps along the strip.
Fold the pastry into three, turning the open edges towards you.
Press the edges lightly together at each end with a rolling pin.
Roll out again into a long strip and repeat until all butter has been used.
Roll out the pastry a total of four times.
If possible, allow the pastry to stand in a cool place for 15 minutes after each rolling.

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.

Shared aroma: isobutyraldehyde (malty, green).
Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Fine flour
- Forms the structure of the pastry once moistened with water.
- Butter or lard
- Forms separate layers that steam apart during baking, creating flakiness.
- Cold water
- Binds the flour into a dough that can be rolled into layers.
The step that matters
Keeping the pastry cool between rollings. If the butter softens and melts into the dough, the layers blend together instead of staying distinct, so the pastry loses its flakiness. Resting in a cool place keeps the fat firm between folds.
