Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Puff Paste
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 flour, salt, lemon juice, and enough cold water to form a firm butter‑like consistency.
Dust your work surface with flour and roll out the paste into a square about 1 inch thick.
Place the butter in the center of the paste and fold the sides over it.
Roll out into an oblong shape to evenly spread the butter.
Fold the dough into thirds and roll out again; repeat this process three more times.
Wrap the dough in a cloth and refrigerate overnight.
Laminate and bake
Roll and fold the dough three more times, then cut out with a sharp cutter.
Bake in a hot oven at 400°F (200°C), dusting off excess flour before folding.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Winter wheat flour
- Forms the gluten network that holds the layers of dough together.
- Unsalted butter
- Creates separate layers that turn to steam in the oven, lifting the pastry into flaky sheets.
- Lemon juice
- Adds a little acidity that helps keep the dough tender.
The step that matters
Keeping the butter in distinct layers. If the butter softens or melts into the dough during rolling and folding, the layers merge and the pastry loses its flakiness. Keeping the dough cold between folds keeps the butter solid until it hits the hot oven.

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