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 dough aside in a cool place for 5 minutes.
Prepare the remaining 15 ounces of firm butter.
Laminate and fold
Dust a square foot of the surface with flour, place the dough on it, and roll it to ½ inch thick.
Place the 15 ounces of butter in the center and fold the edges over to enclose it.
Flatten the dough lightly with a rolling pin until it is 2 inches thick and cool for 10 minutes.
Roll it lengthwise, fold it in four, and let it rest for 5 minutes; repeat this process two more times, rolling in opposite directions each time.
After the final resting, 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 structure that holds the dough's layers together.
- Butter
- Forms separate solid layers that turn to steam and lift the dough when baked.
- Ice water
- Keeps the dough cold and hydrates the flour without warming the butter.
The step that matters
Keeping the butter and dough cold while folding. If the butter softens and blends into the dough instead of staying in distinct layers, it will not steam apart during baking, so the pastry loses its flaky rise. Chilling between folds keeps the layers separate.
