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 dough
In a bowl, sift the flour and mix in the salt until free of lumps.
Combine the flour with water and lemon juice to form a paste similar to ordinary butter.
Make the puff paste in a cool area, avoiding a hot kitchen.
Laminate
On a lightly floured surface, roll out the paste to about ½ inch thick.
Dot the surface with small pieces of butter and lard, spaced apart.
Fold the paste in half, roll it out again, and 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.
Bake
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
- Butter
- Forms the layers of fat that separate the dough, creating flakiness when baked.
- Lard
- Adds fat between the dough layers, helping produce a flaky, tender texture.
- Flour
- Provides the structure that holds the layers of dough together.
The step that matters
Keep the paste cool while laminating. If the dough and fat get warm, the butter and lard soften and blend into the dough instead of staying in separate layers, so the pastry loses its flaky rise.
