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, Simple and Economical
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the flour, egg yolk, and salt in a bowl.
Gradually add cold water and lemon juice to form a smooth, elastic paste.
Flour your work surface and rolling pin, then roll out the paste evenly.
Laminate the dough
Place pieces of butter or lard on the paste without spreading it.
Fold the edges of the paste over the fat, then roll it up like a jelly roll.
Flatten the rolled paste slightly, turn it, and roll it out again.
Cool the paste for 5 minutes in cold weather or 15 minutes in warm weather.
Repeat the rolling and cooling process two more times for best results.
Brush with lemon juice after each roll for better flakiness.
Bake
Bake in a hot oven at 400°F (200°C) or refrigerate for a few hours before baking.

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.
- Butter or lard
- Forms separate layers of fat that melt and create flaky layers when baked.
- Cold water
- Hydrates the flour to form the dough while keeping the fat from melting early.
- Egg yolk
- Adds richness and helps bind the dough.
- Lemon juice
- Adds acidity that tenderizes the gluten, making the dough easier to roll.
The step that matters
Place the fat without spreading it, and keep the paste cool. Fat must stay in distinct pieces so separate layers form. If the butter warms and smears into the dough, the layers merge and the pastry loses its flakiness. Cooling between rolls keeps the fat firm.

Fit is the average pairing score against flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
