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
Combine flour and salt with butter in a bowl, rubbing until fine.
Beat the yolk of the egg in a cup, then add cold water and stir.
Add the egg mixture to the flour mixture and mix well.
Knead on a floured surface until smooth.
Laminate
Roll out the dough thinly.
Cut the remaining butter into thin slices and spread the butter slices over the dough.
Dust the dough with flour.
Fold the dough from all sides.
Roll out the dough again.
Repeat the folding and rolling process two more times.
Shape and bake
Cut the dough into desired shapes.
Brush the shapes with egg.
Bake in a 400°F (200°C) oven.

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 structure that holds the dough's layers together.
- Butter
- Creates separate layers that turn to steam in the oven, lifting the pastry.
- Egg yolk
- Adds richness and helps the pastry brown when brushed on the shapes.
- Cold water
- Hydrates the flour to form a dough while keeping the butter cold and firm.
The step that matters
Spreading and folding the butter layers. Butter must stay cold and in distinct sheets between dough layers. If it softens or blends in, the layers merge and the pastry will not rise flaky.
“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.
