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 ↓
Paste Puff for Tarts, Etc
Ingredients
Directions
Prepare the paste
Take 3 ounces of flour from the pound for working the pastry.
Mix the remaining flour with the baking powder in a bowl. Rub one portion of the butter into the flour.
Add enough water to form a smooth paste. Roll out the paste to about 1 inch thick.
Divide the paste in half. Set one half aside.
Laminate the dough
Roll out the other half until it is very thin, less than ¼ inch thick. Break the second portion of butter into small pieces.
Place the butter pieces over the paste, leaving a 1‑inch margin. Dredge lightly with some of the reserved flour.
Fold the paste into thirds. Roll out the paste to 1 inch thick.
Repeat the process with the other half of the paste and the remaining butter. Stack the two pieces on top of each other.
Roll out the stack to ½ inch thick. Fold the paste.
Rest
Place it between two dishes. Refrigerate until the next day.

Shared aroma: isobutyraldehyde (malty, green).
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 paste its structure.
- Unsalted butter
- Creates separate fat layers that turn into flakiness when baked.
- Baking powder
- Releases gas to help the dough rise and lighten.
The step that matters
Keeping the butter in distinct layers. Rolling and folding must leave the butter in cold, separate sheets. If the butter softens and blends into the flour, the layers merge and the pastry loses its flakiness.
