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 ↓
Puff Paste
Ingredients
Directions
Make the dough
Sift the flour onto a clean surface and make a well in the center.
Add the salt, lemon juice, and cold water to the well.
Knead the mixture thoroughly to form a dough.
Roll the dough into an oblong strip.
Laminate
Knead the butter in a cloth to remove moisture and shape it into a flat cake.
Place the butter in the center of the dough, wet the edges with cold water, and fold over to enclose the butter.
Roll out the dough carefully, fold it into thirds, and roll it out again.
Repeat this process four to five times, resting the dough in a cool place for 15 minutes between each turn.
Allow the dough to stand for at least 30 minutes 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
- All-purpose flour
- Forms the gluten network that gives the dough its structure and elasticity.
- Fresh butter
- Forms separate layers within the dough that steam apart during baking, producing flakiness.
- Cold water
- Hydrates the flour to form the dough while keeping the butter firm and separate.
- Lemon juice
- Adds a little acidity and helps keep the dough tender by limiting gluten toughening.
The step that matters
Enclosing and rolling the butter layers. The butter must stay cold and in an even sheet inside the dough. If it softens or breaks through, the layers merge and the pastry loses its flakiness. Resting the dough between turns keeps the gluten relaxed and the butter firm.
