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 says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the butter
Wash the butter in cold water. Squeeze the butter in cold water. Dry the butter well in a floured cloth.
Shape the butter into a square about the size of a slice of sandwich bread. Keep the butter cool.
Make the dough
Sift the flour onto a marble slab or board. Make a well in the center of the flour. Add the lemon juice to the well.
Gradually add cold water until a smooth paste forms. Adjust the paste for the butter's consistency. Knead the paste until smooth.
Laminate and bake
Roll the paste out into a strip wider than the butter and more than twice its length. Place the butter on one half of the paste. Fold the other half of the paste over the butter. Press the edges together with a rolling pin.
Let the pastry rest in a cool place for 15 minutes.
Roll the pastry out to about three times its original length, keeping the width the same. Fold the pastry into thirds. Turn the pastry so the folded edges are on the right and left. Roll and fold the pastry again.
Repeat the folding process until the pastry has been rolled out six times. Sprinkle with flour as needed. After the sixth roll, the pastry is ready for use.
Bake in a hot oven at 400°F (200°C) without opening the door until partially baked.

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 holds the layers apart.
- Butter
- Forms separate layers that turn to steam in the oven, lifting the pastry into flaky leaves.
- Cold water
- Hydrates the flour to form a workable dough while keeping the butter firm and cool.
- Lemon juice
- Adds acidity that gently tenderizes the gluten, making the dough easier to roll.
The step that matters
Keep the butter cool. If the butter softens and blends into the dough, the separate layers are lost and the pastry will not rise flaky. Chilling between rolls keeps the butter in distinct sheets.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter):
- Raisinfits better
- Vanillafits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
