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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix flour, lard, butter, and salt in a bowl.
Add ice-cold water using a knife to form a firm dough.
Wrap the dough in a napkin and refrigerate until ready.
Laminate and shape
Roll out the dough very thin.
Spread with butter. Sprinkle with flour. Repeat this process three times.
Prepare the pie.
Bake
Bake in a preheated oven at 400°F (200°C).

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
- Flour
- Forms the gluten network that gives the dough its structure.
- Lard
- Coats flour particles to shorten gluten and create a tender, flaky texture.
- Butter
- Adds flavour and creates layers that puff into flakes when baked.
The step that matters
Keep the dough cold. Cold fat stays in solid pieces while the dough is rolled and folded. In the oven it melts and releases steam, which separates the layers into flakes. Warm fat blends into the flour and makes the crust dense and greasy.
