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 ↓
How to Make Pastry Rough Puff Paste
Ingredients
Directions
Prepare the dough
Put the flour in a bowl and lightly rub in half of the butter with your fingertips.
Add a pinch of salt and the lemon juice, mixing with a spoon.
Turn the mixture onto a floured board and roll it out to about ¼ inch thick.
Laminate
Drop small pieces of the remaining butter onto the dough.
Dust the dough with flour.
Fold the dough over three times.
Roll the dough out again.
Repeat the process of dropping butter, dusting flour, folding, and rolling out three times.
Roll the dough out to the desired thickness.
If making tartlets, cut into rounds with a pastry cutter.

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 of the dough once it is mixed with liquid and rolled.
- Butter
- Forms separate layers that puff up as the pastry bakes, giving a flaky texture.
- Lemon juice
- Adds a small amount of acidity that helps tenderize the dough.
The step that matters
Keeping the butter in distinct pieces while folding. Butter that melts into the dough is absorbed by the flour rather than forming separate layers, so the pastry will not puff as well. Keeping the dough and butter cool and rolling gently helps the layers stay distinct.
