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 ↓
Modern Cookery
Ingredients
Directions
Prepare the butter
Press moisture from the butter and form it into a ball without softening it too much.
If the butter is too warm, cool it in a basin of salted water for an hour.
Laminate the dough
Roll out the crust square and large enough to enclose the butter.
Flatten the butter in the center of the crust, fold the crust over it, and roll it out thinly.
Dredge the board and rolling pin with flour before rolling.
Fold the dough in thirds and roll it out again, repeating this process for a total of six turns.
After the final turn, fold the dough once more and it will be ready for use.

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
- All-purpose flour
- Forms the gluten structure that holds the layers of the dough together.
- Unsalted butter
- Creates separate flaky layers as it melts and steams during baking.
- Egg yolks
- Add richness and fat, tenderizing the dough and helping it bind.
The step that matters
Keeping the butter cold and workable. If the butter softens too much it blends into the dough instead of forming distinct layers, so the pastry loses its flakiness. Cooling warm butter keeps it firm enough to roll between the dough layers.
