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 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
Combine flour and salt in a bowl.
Cut in the lard with a knife until the mixture resembles fine crumbs.
Add ice water and mix with the knife until no flour remains.
Laminate the dough
Roll the dough thin.
Place small bits of butter over the rolled dough.
Dredge the dough with flour.
Fold the dough.
Repeat the dredge, fold, and roll process twice.
Roll the crust thin again.
Bake
Bake in a 400°F (200°C) oven until it rises in flakes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 structure that holds the layers together as the crust bakes.
- Lard
- Solid fat cut into the flour, creating pockets that make the crust tender and flaky.
- Butter
- Placed between folded layers, it adds flakiness and rich flavor as it melts in the oven.
- Ice water
- Brings the dough together while staying cold, which limits gluten development and keeps fat solid.
The step that matters
Keeping the butter in pieces through the folds. Flakiness comes from separate layers of fat between dough sheets. If the butter softens and smears into the dough during rolling, the layers merge and the crust bakes dense instead of flaky.
