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 ↓
Fine Puff-Paste
Ingredients
Directions
Prepare the dough
Mix the flour, baking powder, and salt in a bowl, then sift again.
Rub the cold lard into the flour until a fine paste forms.
Combine the ice water and beaten egg white, then add gradually to form a stiff dough.
Laminate
Roll out the dough into a thin sheet and spread with one quarter of the butter.
Sprinkle with a little flour, then roll tightly like a scroll.
Fold the ends toward the center, flatten, and re-roll.
Repeat the rolling process with the remaining butter.
Chill
Cover the dough and refrigerate for at least one hour before using.

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 structure that holds the layers of dough together.
- Butter
- Creates separate layers that steam and lift the dough as it bakes.
- Lard
- Shortens the flour, giving the dough a tender, flaky texture.
- Baking powder
- Releases gas that helps the dough rise and lighten.
- Egg white
- Adds structure and helps bind the stiff dough.
The step that matters
Keeping the fat cold while laminating. If the butter softens and blends into the dough, it will not form distinct layers. Cold fat stays solid during rolling, so when it melts in the oven it leaves air pockets that make the pastry flaky.
