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
Sift the flour onto a pastry board.
Make a well in the center of the flour.
Add the salt, lemon juice, and cold water to the well.
Knead the mixture thoroughly.
Roll the dough into an oblong strip.
Prepare the butter
Wrap the butter in a cloth.
Knead the wrapped butter slightly to remove moisture.
Shape the butter into a flat cake.
Laminate and rest
Place the butter in the center of the dough.
Wet the edges of the dough with cold water.
Fold the dough over to enclose the butter.
Roll the dough out carefully.
Fold the dough into thirds.
Roll the dough out again.
Repeat the folding process four to five times.
Rest the dough in a cool place for 15 minutes between each turn.
Allow the dough to stand for at least 30 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
- Flour
- Provides the structure that holds the dough together and traps the layers of butter.
- Butter
- Forms separate layers that puff into flaky pastry when the dough is folded and baked.
- Cold water
- Hydrates the flour to form a dough that can be rolled without toughening.
- Lemon juice
- Adds a little acidity that helps keep the dough tender and relaxed.
The step that matters
Keep the butter and dough cold between turns. If the butter softens and melts into the dough, the layers blend together and the pastry will not puff. Resting the dough in a cool place keeps the butter firm enough to form distinct layers.

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