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 ↓
Puff Paste
Ingredients
Directions
Prepare
Choose a cool area in the kitchen for making the pastry.
Wash your hands in hot water to cool them before starting.
If no refrigerator is available, prepare a basin of ice in a cool part of the larder.
Make the dough
Combine equal weights of sweet butter and Vienna flour in a bowl.
Add a pinch of salt, lemon juice, and enough cold water to form a workable dough.
Knead the dough until smooth, then let it rest for about five minutes.
Laminate and fold
Roll out the dough into a square, placing the cold butter in the center.
Fold the dough over the butter, sealing it securely.
Roll out again and fold as before to create layers.
Repeat the rolling and folding process until the dough is flaky.

Butter and flour 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
- Sweet butter
- Forms the separate fat layers that puff into flaky sheets when the dough is rolled and folded.
- Vienna flour
- Provides the gluten structure that holds the dough together and supports the layers.
- Lemon juice
- Adds a little acidity that helps keep the dough tender and workable.
The step that matters
Keeping the butter cold during rolling and folding. If the butter softens and blends into the dough, it cannot separate into distinct layers, so the pastry will not puff. Keeping the dough cool between folds preserves the layers that steam and expand in the oven.
