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 ↓
Pie Crust
Ingredients
Directions
Make the dough
In a bowl, combine flour and salt.
Rub in the cold lard until the mixture resembles coarse crumbs.
Gradually add ice water, mixing until the dough holds together.
Shape the crust
On a floured surface, roll out half of the dough for the bottom crust.
Roll out the remaining dough for the top crust.
Spread the top crust with soft butter or lard.
Fold the top crust over the bottom crust.
Roll the folded top crust again.
Cut holes in the top crust for ventilation.
Dampen the edge of the bottom crust with ice water or beaten egg before placing the top crust on.

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
- Flour
- Forms the main structure of the crust once mixed with liquid.
- Cold lard
- Stays in solid pieces that melt in the oven, creating flaky layers and tenderness.
- Ice water
- Adds moisture to bind the dough while keeping it cold and limiting gluten development.
The step that matters
Rubbing in the cold lard. Lard should stay in small cold pieces among the flour. As it melts in the oven it leaves gaps that become flaky layers. If the lard warms or is fully blended in, the crust turns dense and tough.
