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
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Make a hole in the flour.
Add a pinch of salt.
Mix with cold water until a dough forms, using about ½ cup.
Laminate
Roll the dough to ¼ inch thick.
Spread ½ pound of butter evenly over the dough.
Fold the dough in four.
Roll it out again.
Fold it four more times.
Use flour to prevent sticking.
Shape and bake
Cut with a pastry cutter.
Brush with egg yolk mixed with a little water.
Bake in a 400°F (200°C) oven for 15 minutes without opening the door for the first 10 minutes.

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 gluten network that gives the dough its structure.
- Butter
- Forms separate layers that steam apart during baking, creating flakiness.
- Cold water
- Hydrates the flour to form the dough while keeping the butter firm.
- Egg yolk
- Gives the surface a glossy golden browning when brushed on before baking.
The step that matters
Spreading the butter and folding. The butter must stay cold and be spread into an even layer, so that the dough and butter form distinct thin layers. If the butter softens and blends in, the layers are lost and the pastry will not puff.
“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.
