  1. Sift flour into a bowl. Cut in lard.

  2. Add a pinch of salt. Mix to form a dough with cold water.

  3. Flour your pastry board. Turn out the dough.

  4. Roll out to ½ inch thick. Sprinkle lightly with flour. Roll again.

The flavor team

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
Cut into the flour to create fat pockets that keep the pastry tender and flaky.
Butter
Folded in as layers that separate the dough, producing flakiness when baked.
Cold water
Hydrates the flour to bind the dough while keeping the fat firm.

The step that matters

Keeping the fat in distinct layers. Rolling and folding must keep the butter and lard as separate sheets rather than letting them smear into the dough. Distinct solid fat layers melt during baking and leave steam pockets that make the pastry flaky. Resting the dough lets the gluten relax so it rolls out without tearing.
