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 for Pies
Ingredients
Directions
Make the dough
Sprinkle salt into the flour and mix in the butter until smooth.
Quickly add cold water and mix until combined.
Assemble the pie
Roll out the dough and fit it into a pie plate, using flour to prevent sticking.
Trim the edges of the crust and gather scraps to make a top crust.
Roll out the top crust thinner than the bottom, then cut slits in the center for steam to escape.
Fill the pie with your desired filling, wet the edge of the rim, and place the top crust over the filling.
Press the edges together with your thumb, dipping in flour to prevent sticking.
Bake
Bake until the crust is light brown.

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
- Provides the gluten network that gives the dough its structure.
- Unsalted butter
- Creates flaky layers and tenderness as it stays solid in the dough and melts in the oven.
- Cold water
- Binds the flour and butter into a dough while keeping the fat firm.
The step that matters
Quickly add cold water and mix until combined. Working the dough quickly and keeping the water cold stops the butter from softening and the gluten from overdeveloping. Warm or overworked dough becomes tough and loses its flaky layers.
