    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

All-purpose flour
Forms the structure of the dough when mixed with water.
Butter or lard
Coats flour particles to keep the pastry tender and flaky.
Baking powder
Releases gas that gives the pastry a light rise.

The step that matters

Add cold water gradually until the mixture holds together. Too much water or overworking the dough lets gluten develop, making the pastry tough. Stopping as soon as the dough holds together keeps it tender. Cold water also keeps the fat solid, which helps create flaky layers.
