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
In a basin, combine flour and salt.
Make a hole in the center, add lemon juice, and mix with cold water to form a smooth paste.
Turn the paste onto a floured board and knead until smooth.
Laminate
Roll into a long strip, wet the edges with butter, and place butter in the center.
Fold the paste over the butter in thirds and refrigerate for 30 minutes.
Flour the board and roll out the paste, keeping it square at the ends.
Fold it in thirds again, turn it with rough edges facing you, and repeat rolling and folding twice more.
Shape and bake
Roll the dough out to ⅓ inch thick for patties.
Cut rounds with a floured cup, then cut smaller rounds in the center.
Brush the tops with egg white and bake in a 400°F (200°C) oven for 6 to 10 minutes.
Remove the cut centers and any moist paste from inside the patty cases.

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 structure of the paste and sets into layers when baked.
- Butter
- Sits between the dough layers, creating flaky separation as it melts and steams.
- Cold water
- Hydrates the flour to form a smooth, workable dough.
- Lemon juice
- Adds a little acidity that tenderizes the gluten in the dough.
The step that matters
Folding in thirds with butter. If the butter gets too warm or breaks through the dough, the layers blend instead of separating, so the pastry turns out dense rather than flaky. Keep the dough cold between folds.

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