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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Mix the butter in cold water to remove salt and let it harden.
Roll out the dough and place half of the butter in small pieces on top.
Fold the ends and roll the dough thin, then repeat this process twice.
Use the remaining butter for the final roll.
Chill and bake
Chill the dough in the refrigerator for at least 1 hour before using.
Minimize flour usage while rolling for a better paste.
Bake in a hot oven at 400°F (200°C), covering with paper to prevent scorching.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 and sheets.
- Butter
- Forms separate fat layers that melt and steam during baking, lifting the dough into flaky layers.
- Ice water
- Keeps the dough cold and moderates gluten development so the dough rolls without toughening.
The step that matters
Keep the butter cold and the dough chilled. Cold butter stays in solid pieces between the dough sheets. If it softens and blends into the dough, the layers are lost and the pastry bakes dense instead of flaky.
