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 ↓
Feuilletage, or Fine French Puff Paste
Ingredients
Directions
Prepare the butter
Chill the butter over ice before use.
Press moisture from the remaining butter.
If the butter is too soft, cool it in a basin of salted water for an hour.
Make the dough
Break small bits of butter into the flour.
Place salt in the center of the flour mixture.
Add enough water to dissolve the salt.
Gradually moisten the flour to form a smooth paste.
Form the mixture into a ball without softening it too much.
Laminate and roll
Roll the crust out into a square shape.
Place the butter in the center of the crust.
Fold the crust over the butter.
Roll out the crust thinly.
Dust the board with flour as needed.

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
- Butter
- Cold butter stays in solid pieces that create separate layers, which puff into flaky texture when baked.
- Flour
- Forms the gluten structure that holds the dough together and supports the layers.
- Water
- Hydrates the flour to form the dough and dissolves the salt.
- Salt
- Seasons the dough and dissolves into the water to flavour the pastry.
The step that matters
Keeping the butter cold and firm. If the butter softens and blends into the dough, it cannot form separate layers, so the pastry will not puff into flaky sheets. Chilling and avoiding overworking keep the butter in distinct pieces.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
