    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.

What each ingredient does

Lard
Rubbed into flour to shorten gluten and give the pastry a tender, crumbly texture.
All-purpose flour
Forms the structure of the pastry as its proteins hydrate into gluten.
Butter
Laminated into the dough, creating layers and flakiness and adding rich flavor.

The step that matters

Keeping the fat cool while rolling. Lard and butter must stay cold so they stay in solid pieces. When they melt into the flour, the layers blend in and the pastry loses its flakiness.
