Ingredients
- 240g all-purpose flour
- 1 teaspoon granulated sugar
- 1/2 teaspoon fine sea salt
- 170g unsalted butter, very cold, cut into 1/2-inch cubes
- 60g active sourdough starter or unfed discard, chilled
- 60-80ml ice water
Instructions
Step 1
In a large bowl, whisk together the all-purpose flour, granulated sugar, and fine sea salt until well combined. Ensure these dry ingredients are evenly distributed for consistent flavor.
Step 2
Add the very cold butter cubes to the dry ingredients. Use a pastry blender, your fingertips, or a food processor to cut the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining.
Step 3
In a separate small bowl, whisk together the chilled sourdough starter (or discard) and 60ml of ice water. This ensures the starter is evenly distributed before adding to the dough.
Step 4
Pour the sourdough-water mixture over the flour and butter mixture. Use a fork to gently mix until the dough just starts to come together, adding more ice water, one tablespoon at a time, if needed, until a shaggy dough forms.
Step 5
Turn the shaggy dough out onto a lightly floured surface. Gently gather and press the dough together a few times, forming it into two equal discs without overworking.
Step 6
Wrap each dough disc tightly in plastic wrap and refrigerate for at least 2 hours, or preferably overnight. This chilling period is crucial for hydrating the flour and firming up the butter, which prevents shrinkage.
Step 7
When ready to use, remove one disc of dough from the refrigerator and let it sit at room temperature for 5-10 minutes to soften slightly. On a lightly floured surface, roll out the dough into a 12-inch circle, rotating and flouring as needed to prevent sticking.
Step 8
Carefully transfer the rolled dough to your pie plate. Trim the edges and crimp as desired. Fill and bake according to your pie recipe's instructions.
