  3. Gradually add ice cold water, stirring with a knife.

    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 main structure of the dough once hydrated with water.
Butter
Creates flaky layers as it stays solid in the dough and melts during baking.
Lard
Adds tenderness and flakiness by keeping pockets of fat separate within the dough.
Ice cold water
Hydrates the flour while keeping the fat cold so the dough stays flaky.

The step that matters

Keep everything cold and work quickly. Cold fat stays in solid pieces that melt in the oven, leaving flaky layers. If the fat softens and blends into the flour, the pastry turns tough and greasy instead of flaky.
