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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the butter and squeeze out all the milk and water, then flatten it.
Add salt to the flour and cut in the lard with a knife.
Make the dough
Moisten the mixture with cold water.
Toss the dough on a lightly floured surface, pat and roll it out.
Fold in the butter, roll out, and repeat folding and rolling several times.
Rest and bake
Cover with cheesecloth and set aside in a cool place, avoiding direct contact with ice.
Roll thin and bake in a preheated oven at 350°F (175°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
- All-purpose flour
- Forms the structure of the pastry as its proteins hydrate into gluten with water.
- Unsalted butter
- Creates thin layers through folding that puff and flake as the water in the butter turns to steam.
- Lard
- Coats flour particles to shorten gluten strands, giving the pastry a tender, crumbly texture.
The step that matters
Fold in the butter, roll out, and repeat folding and rolling several times.. Each fold builds separate layers of fat and dough. The fat must stay cold so it does not melt into the flour, which would destroy the layers and leave the pastry dense instead of flaky.
