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
Ensure the flour is dry and sift it.
Remove moisture from the butter by squeezing it in a clean cloth.
Place the flour on a clean surface and mix in 2 ounces of butter lightly.
Make a well in the center and add the egg yolks, salt, and water.
Make the dough
Knead the mixture quickly until smooth, then roll it out to ½ inch thick.
Roll the remaining butter into a ball and place it on the paste.
Fold the paste over the butter and seal it well.
Roll the paste thin, dusting with flour as needed.
Fold the paste into thirds and roll it out again.
If it's warm, chill the paste between turns.
Repeat rolling and folding two more times for a total of six turns.

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
- Flour
- Forms the structure of the dough once hydrated and worked into gluten.
- Butter
- Forms separate fat layers that turn into flaky layers as the pastry bakes.
- Egg yolks
- Add richness and fat, and help bind the dough together.
- Water
- Hydrates the flour so gluten can develop and the dough holds together.
The step that matters
Keeping the paste and butter cold between turns. If the butter softens and merges into the dough, the separate layers are lost and the pastry will not puff. Chilling between turns keeps the butter firm so it stays in distinct layers.
