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
Prepare the butter and dough
Place the butter on a clean cloth and fold the cloth over it to squeeze out excess water.
Heap the flour on a board and make a well in the center.
Add the salt, lemon juice, and enough water to achieve a consistency similar to the squeezed butter. Mix well.
Laminate the dough
Flour a rolling pin and the board to prevent sticking.
Roll out the paste to about ¼ inch thick.
Place the pat of squeezed butter on one half of the paste. Fold the other half over it, pressing the edges together.
Let the paste rest on a plate in a cool place for 15 minutes.
Roll out the paste again and fold it into thirds.
Turn the paste so the rough edges face you.
Roll it out and fold it into thirds again. Let it rest for another 15 minutes before using.

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 layers of dough together.
- Fresh butter
- Creates separate fat layers that turn to steam in the oven, lifting the pastry into flaky layers.
- Lemon juice
- Adds a little acidity that helps keep the dough tender by limiting gluten toughening.
The step that matters
Keeping the butter and dough at a similar consistency while rolling. If the butter is softer or firmer than the dough, it breaks through or blends in instead of forming separate layers. Those layers are what make puff pastry rise flaky. Resting the dough in a cool place keeps the butter firm between folds.
