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, sift the flour and mix in the salt, ensuring there are no lumps.
Combine the flour with water and lemon juice to form a paste similar in firmness to ordinary butter.
On a lightly floured surface, roll out the paste to about ½ inch thick.
Laminate the dough
Dot the surface with small pieces of butter and lard, spaced apart.
Fold the paste in half.
Roll it out again.
Add more butter and lard.
Repeat the folding and rolling process until all the butter and lard are used.
Finally, roll out the paste to about ⅓ inch thick.
Keep it cool and bake
Make the puff paste in a cool area, avoiding a hot kitchen.
Bake in a brisk oven for best results.

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 the paste together.
- Butter
- Creates separate fat layers that turn to steam in the oven, lifting the paste into flaky layers.
- Lard
- Adds fat layers that keep the paste tender and help it separate into flaky sheets.
- Lemon juice
- Adds acidity that helps tenderize the gluten, keeping the paste easier to roll.
The step that matters
Keeping the butter and lard in solid pieces while rolling. Fat that softens and blends into the dough cannot form separate layers. Cool conditions keep the fat firm, so steam from it puffs the pastry when it bakes.
