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
Mix flour and cold water in a bowl.
If it is summer, add the egg yolk.
For sweet tarts, add a little sifted white sugar to the flour.
Laminate and roll
Roll out the dough on a marble slab to keep it cool.
Place chilled butter between layers of dough.
Fold and roll out the dough several times, cooling it between turns.

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.
- Unsalted butter
- Stays solid between dough layers and creates steam, separating them into flaky sheets.
- Cold water
- Hydrates the flour to form a dough while keeping it cool.
- Egg yolk
- Adds richness and helps bind the dough.
The step that matters
Keep the butter and dough cold between turns. If the butter softens and blends into the dough, the layers merge and the pastry loses its flakiness. Chilling between folds keeps the butter in distinct layers that puff when baked.
