Why it works: Butter and flour 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 ↓
To Make Puff Paste
Ingredients
Directions
Prepare
Mold the butter with your hands and place it in cold water.
Sift the flour and rub half of the butter into it.
Make the dough
Mix the flour with cold spring water to form a dough.
Laminate the dough
Roll out the dough and place pieces of the remaining butter on top.
Fold the dough, roll it out again, and add the rest of the butter.
Dust lightly with flour, fold it together, and refrigerate.
Finish
When ready to use, roll it out twice more.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Butter
- Forms separate layers that puff into flakes as moisture turns to steam in the oven.
- Flour
- Its gluten network forms the dough that holds the thin layers together.
The step that matters
Keep the butter cold while rolling and folding. If the butter softens and blends into the dough, it cannot form distinct layers, so the pastry will not puff and flake properly.
