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 ↓

Puff Paste

Ingredients

Directions

Prepare the fat and flour

  1. Combine the lard and butter in a bowl.

  2. Rub one-third of the shortening into the flour.

Make and chill the dough

  1. Beat the egg and mix it with enough cold water to create a dough with the same consistency as the shortening.

  2. Roll the remaining shortening into the dough.

  3. Place the dough in a cool place until thoroughly chilled.

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: decanal (soap, orange peel).

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
Provides the structure that holds the dough together and sets during baking.
Unsalted butter
Adds rich flavor and creates flaky layers as its water turns to steam.
Lard
Keeps the dough tender and helps form separate, flaky layers.
Egg
Binds the dough and adds richness and structure.

The step that matters

Keep the fat cold and in pieces. Solid fat left in distinct pieces melts during baking and releases steam, pushing the dough into flaky layers. If the fat softens and blends into the flour, those layers are lost and the pastry turns dense.
