Why it works: Butter and flour 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 for Tarts and Patties
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the ice water and flour to form a soft dough.
Flour the kneading board and roll the dough into a square about ¼ inch thick.
Laminate the butter
Drop half the butter in walnut‑sized lumps onto the dough, sift flour over it, and press the butter slightly into the dough.
Fold the dough into thirds, roll it out to the same size, and repeat with the remaining butter.
Fold the dough into thirds again and roll it out six times total.
After the final roll, cut out shapes with a pattie cutter.
Bake
Brush the shapes with milk or a mixture of milk and egg yolk.
Bake in a moderate oven at 350°F (175°C) for about 20 minutes.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour 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
- Butter
- Forms separate solid layers that steam apart in the oven, giving puff pastry its flakiness.
- Flour
- Forms the gluten network that holds the dough together and gives the layers structure.
- Ice water
- Hydrates the flour to form the dough while keeping the butter cold so it stays in distinct layers.
The step that matters
Keeping the butter in distinct layers while rolling. If the butter softens or melts into the dough, the layers merge and the pastry will not puff. Keeping the dough and butter cold between folds and rolling evenly preserves the separate layers that steam apart during baking.
