How to Make Sourdough Discard Pie Crust

Step 1: Mix the Dry Ingredients

In a large bowl, whisk together:

• Flour
• Salt
• Sugar (if using)

Step 2: Cut in the Butter

Add the cold cubed butter.

Using a pastry cutter or fingertips, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.

The visible butter pieces help create flaky layers.

Step 3: Add the Sourdough Discard

Stir in the sourdough discard.

Add ice water one tablespoon at a time until the dough just comes together.

Avoid adding too much water.

Step 4: Form the Dough

Turn the dough onto a lightly floured surface.

Gently press into a disk.

Do not overwork the dough.

Step 5: Chill the Dough

Wrap tightly in plastic wrap and refrigerate for:

Cold dough prevents shrinking and creates flaky texture.

Step 6: Roll Out the Dough

On a lightly floured surface, roll the dough into a circle about:

$\frac{1}{8}\text{ inch thickness}$81​ inch thickness

Rotate frequently to prevent sticking.

Step 7: Transfer to Pie Dish

Carefully place the dough into the pie dish.

Trim excess edges and crimp as desired.
