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 ↓

Ingredients
Directions
Prepare the dough
Mix flour with water and salt until it reaches the consistency of butter.
Let the dough rest for 30 minutes.
Laminate the dough
Flatten the dough and place the butter on top.
Fold the dough in four and roll it out twice.
Chill the dough for 45 minutes.
Roll it out twice more and chill for another 45 minutes.
Roll it out twice again.
Bake
Place the dough in a large paper bag, ensuring it doesn't touch the bag.
Bake in a preheated oven at 400°F (200°C) for 20 minutes.

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
- Flour
- Forms the gluten network that gives the dough its structure.
- Butter
- Forms separate layers that steam apart in the oven, making the pastry flaky.
- Water
- Hydrates the flour so gluten can form and bind the dough.
The step that matters
Chill the dough between rolls. The butter must stay cold and firm between rolling and folding. If it softens, it blends into the dough instead of forming distinct layers, and the pastry loses its flakiness.
