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, combine 1 pound and 4 ounces of flour with ½ pound of butter, rubbing it in with your hands.
Gradually mix in ½ pint of cold water until well combined.
Knead the dough and let it rest on a floured surface for 15 minutes.
Laminate
Roll the dough out thin and place ¼ pound of butter in small pieces on top.
Sprinkle a little flour over the butter, fold the dough over, and roll it out thin again.
Repeat the process with another ¼ pound of butter, sprinkling with flour each time.
After folding and rolling three times, let the dough rest in a cool place for 1 hour.
Use
When ready to use, roll it out to your desired size.

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 network that gives the dough its structure and holds the layers together.
- Unsalted butter
- Forms separate solid layers that steam in the oven, creating the flaky rise.
- Cold water
- Hydrates the flour to form a dough that can be rolled and folded without melting the butter.
The step that matters
Keeping the butter cold while rolling and folding. If the butter softens and blends into the dough, it will not form distinct layers, so the pastry will not puff properly. Chilling the dough between folds keeps the butter firm.
