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 ↓
Very Fine 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.
Prepare the dough
Beat the egg white and mix with the tablespoon of water.
On a clean surface, place half of the flour and mix it with the egg and water.
Take the other half of the flour and mix it with the butter cut into thin slices.
Rest and layer
Let the mixture rest for half an hour.
Roll out the part mixed with water, then layer on the butter mixture, repeating until all butter is used.
Handle the dough as little as possible.
Bake
Bake in a quick oven at 400°F (200°C).

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
- Fine flour
- Provides the structure that holds the dough together and separates the butter layers.
- Butter
- Forms separate layers that release steam during baking, creating flakiness.
- Egg white
- Helps bind the flour and water into a cohesive dough.
The step that matters
Handle the dough as little as possible. Overworking develops gluten, making the dough tough, and warms the butter so it blends into the flour instead of staying in distinct layers. Those separate layers are what puff during baking.
“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.
