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 ↓
Flaky Pie-crust
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub butter and flour together lightly but firmly.
Keep the flour between the lard and your hands.
Add ice water.
Mix with a knife.
Place dough on a floured board.
Roll it into a thin sheet.
Dot the sheet with ⅓ of the butter.
Sprinkle a little extra flour over it.
Roll the dough up like a sheet of music.
Divide it in half.
Shape the crusts
Divide one half into 3 parts for the bottom crust.
Roll them out to cover the pie plates.
Roll the remaining dough into a thin sheet.
Dot with the remaining butter.
Sift a little flour over it.
Fold the corners toward the center.
Roll it thin again.
Dot with the remaining butter.
Dredge with flour.
Fold as before but do not roll out quite as thin.
Roll into a thick scroll.
Cut off a piece of the scroll.
Flour both ends.
Roll it thin.
Use 3 thin layers for each cover instead of 1 thick layer.
Notch the edges together.
Trim neatly.
Always roll in the same direction — from you.
Bake
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
- Flour
- Provides the structure that holds the pastry together once baked.
- Butter
- Creates flaky layers as it melts and steams during baking, and adds richness.
- Lard
- Shortens the gluten network, producing a tender, crumbly texture.
- Ice water
- Hydrates the flour while keeping the fat cold, so the dough stays workable and flaky.
The step that matters
Keep the fat cold and the dough handled lightly. Cold butter and lard stay in solid pieces that melt in the oven and leave flaky layers. Warm fat blends into the flour, and overworking develops gluten, making the crust tough.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
