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 clean bowl, gently rub ½ pound of butter into 1 ¼ pounds of flour with your hands.
Gradually mix in ½ pint of cold water until well combined.
Knead the mixture and let it rest on a floured surface for 15 minutes.
Laminate
Roll out the dough thinly.
Place ¼ pound of butter in small pieces on top of the dough. Sprinkle a little flour over the butter.
Fold the dough over. Roll the dough out thin again.
Repeat the process with another ¼ pound of butter. Sprinkle with flour. Fold the dough.
Rest
Let the dough rest in a cool place for 1 hour before using.

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
- All-purpose flour
- Forms the gluten structure that holds the dough's layers together.
- Unsalted butter
- Creates separate fat layers that turn to steam in the oven, lifting the pastry into flaky layers.
- Cold water
- Hydrates the flour so it forms a workable dough while keeping the butter cold and separate.
The step that matters
Keeping the butter cold and in distinct layers. If the butter softens and blends into the dough, it will not form separate layers. Cold, firm butter stays in pieces that melt during baking and release steam, which lifts the dough into flaky layers.
