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
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
Sift the flour and salt several times.
Cut the lard into the flour until it resembles coarse crumbs.
Stir in the ice cold water with a spoon.
Divide the dough into two equal parts.
Roll and shape
Roll out one part for the bottom crust.
Roll out the second part to ⅛ inch thick.
Dot the rolled dough with butter and lightly dredge with flour.
Fold the dough to the smallest size possible and pat with a rolling pin.
Roll out again, pressing the rolling pin in different directions.
Slash the dough with a knife to create a design.
Assemble and bake
Lay the dough over the fruit in the pan, pinch the edges together, and trim.
Bake in a hot oven at 400°F (200°C).

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 crust its structure.
- Lard
- Coats flour particles in solid fat, keeping the crust tender and flaky.
- Ice cold water
- Hydrates the flour just enough to bind the dough without making it tough.
- Butter
- Adds flavor and creates pockets of steam for flakiness when it melts in the oven.
The step that matters
Keep the lard and water ice cold. Solid fat pieces stay separate from the flour until baking. As they melt, they release steam that lifts the layers, creating flakiness. Warm fat blends into the flour and makes the crust dense and tough.
