Flaky Pastry

Ingredients

Directions

Prepare the dough

  1. Mix the lard and butter together and divide into four parts.

  2. Rub one part of the lard and butter mixture into the flour with a pinch of salt.

  3. Add lemon juice to the cold water and mix to form an elastic dough.

  4. Turn the dough out onto a board and work it lightly.

Laminate and rest

  1. Roll out the dough and place one part of the lard and butter mixture in small pats on top.

  2. Flour the surface, fold the dough, and roll it out again.

  3. Repeat the process with the remaining lard and butter mixture.

  4. Set the pastry aside for 30 minutes in a cool place.

  5. Roll out the dough two more times, for a total of five rollings.

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
Forms the structure of the pastry once mixed with water.
Lard and butter
Fat layers pressed between dough sheets melt during baking to create flaky separation.
Cold water
Hydrates the flour to form dough while staying cold so the fat stays solid.
Lemon juice
Acidity tenderizes the gluten, making the dough easier to roll and more elastic.

The step that matters

Keeping the fat in distinct pats while rolling. If the lard and butter softens or smears into the dough, the layers blend together and the pastry loses its flakiness. Keep the dough cool and work it quickly and lightly.

Swap the lemon

How well each one fits the dish's main ingredients (flour, butter):

Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
