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 ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
In a large bowl, combine the sifted flour and salt.
Cut in the lard and butter until the mixture resembles coarse crumbs.
Form the dough
Gradually add the ice water, mixing until the dough comes together.
Form the dough into a ball, wrap in plastic, and refrigerate for at least 30 minutes before rolling out.

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 structure of the dough once hydrated.
- Lard
- Coats flour particles to shorten gluten and give a tender, flaky texture.
- Butter
- Adds flavor and flakiness as small pieces create layers during baking.
- Ice water
- Hydrates the flour to bind the dough while keeping the fat cold.
The step that matters
Keeping the fat cold and resting the dough. If the lard and butter warm and melt into the flour, the crust turns greasy and dense instead of flaky. Chilling the dough relaxes gluten and firms the fat so the crust holds its layers when rolled and baked.
