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.
Prepare the dough
Rub together the butter and flour lightly but firmly, keeping the flour between the lard and your hands, in a bowl.
Add the ice water and mix with a knife until combined.
Place the dough on a floured surface and roll it into a thin sheet.
Laminate
Dot the surface with one-third of the butter and sprinkle with a little extra flour.
Roll the dough up like a sheet of music and divide it in half.
Take one half and divide it into three parts for the bottom crust; roll each part to cover a pie plate.
Roll the remaining dough into a thin sheet, dot with the remaining butter, and sift a little flour over it.
Fold the corners toward the center, roll it out again, and dot with the remaining butter.
Dredge with flour, fold as before, but do not roll out as thin.
Roll into a thick scroll, cut off a portion to cover each pie, flour both ends, and roll it thin.
Use three thin layers for the cover instead of one thick layer, notching the edges together and trimming neatly.
Always roll in the same direction, away from you.
Bake
Bake in a 400°F (200°C) oven.

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 crust once mixed with liquid and rolled.
- Butter
- Creates flaky layers as it stays in pieces and melts during baking.
- Lard
- Keeps the crust tender and short by coating flour particles with fat.
- Ice water
- Binds the dough while staying cold, so the fat does not melt into it.
The step that matters
Keep the butter and dough cold while rolling and folding. If fat softens and blends into the flour, the layers merge and the crust turns dense instead of flaky. Chilled fat stays in distinct pieces that steam apart during baking.
