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 ↓
Feuilletage, or Puff Paste
Ingredients
Directions
Make the dough
Place the flour on a clean surface and make a hollow in the center.
Add 1 ounce of butter, ice water, and salt into the hollow and mix well.
Set the mixture aside in a cool place for 5 minutes.
Prepare the remaining 15 ounces of firm butter and dust a square foot of the surface with flour.
Laminate
Roll the dough to ½ inch thick.
Place the butter in the center of the dough.
Fold the edges over the butter to enclose it.
Flatten lightly to form a 2-inch thick piece.
Cool the dough for 10 minutes.
Roll the dough lengthwise.
Fold the dough in four.
Let the dough rest for 5 minutes.
Repeat the rolling and folding process two more times.
Roll the dough in a different direction each time.
Let the dough rest for 5 minutes.
Finish
The puff paste is ready to use.

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 for holding layers.
- Fresh butter
- Forms separate solid layers that create steam and lift, producing the flaky puff.
- Ice water
- Keeps the dough cold and hydrates the flour so it stays workable without melting the butter.
The step that matters
Keeping the butter and dough cold. If the butter softens and blends into the dough instead of staying in distinct layers, steam cannot separate the layers during baking, so the pastry loses its flaky rise.
