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 ↓
Puff Paste
Ingredients
Directions
Make the dough
In a bowl, mix the flour and salt.
Add lemon juice to the cold water and mix it into the flour until it has the same consistency as the butter.
Knead the mixture well and set aside for 5 minutes.
Laminate
Squeeze out moisture from the butter and form it into a pat.
Roll out the paste to ½ inch thick, place the butter in the center, and fold the paste over it.
Press the edges together and roll out again.
Fold the dough in thirds, turn the rough edges towards you, and roll out again.
Place the dough in a cool place for 10-15 minutes.
Repeat the rolling process until the paste has been rolled out seven times, cooling between every two rolls.

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
- Hungarian flour
- Forms the gluten network that gives the dough its structure and layers.
- Fresh butter
- Forms separate layers that puff apart into flakes when the dough is rolled and folded.
- Cold water
- Hydrates the flour to form the dough while keeping the fat from melting into it.
- Lemon juice
- Adds acidity that slightly weakens gluten, making the dough easier to roll.
The step that matters
Keep the butter and dough cool between rolls. If the butter softens or melts into the dough, the layers blend together instead of separating, so the pastry will not puff into flaky layers. Chilling between rolls keeps the fat solid.
Swap the lemon

Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
