Puff Pie Crust

Ingredients

Directions

Prepare the fat

  1. Cut the lard and butter together in a bowl.

Make the dough

  1. Rub one-third of the lard into the flour.

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

  3. Roll the remaining lard into the dough.

  4. Chill the dough in a cool place until thoroughly chilled.

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 dough once mixed with liquid.
Lard
Its solid fat coats flour particles, keeping layers separate for a flaky texture.
Butter
Adds flavor and fat that creates flaky layers as it stays solid in the dough.
Egg
Adds richness and helps bind the dough together.

The step that matters

Chill the dough until thoroughly chilled. Cold fat stays in solid pieces during rolling. If the dough is warm, the fat melts into the flour, and the crust becomes tough rather than flaky.
