Step‑by‑Step Instructions for Sourdough Discard Pop Tarts
Step 1: Dough Preparation
In a food processor, combine all-purpose flour and salt, then add cold butter cut into small cubes. Pulse until the mixture resembles coarse crumbs. Introduce the sourdough discard and apple cider vinegar, continuing to pulse until a tacky dough forms. This process should take about 1-2 minutes. Chill the dough in the refrigerator for at least 1 hour for ideal flakiness, or up to 48 hours for better flavor development.
Step 2: Preheat Oven
Once the dough has chilled, preheat your oven to 350°F (177°C). Prepare a baking sheet by lining it with parchment paper, ensuring a non-stick surface for the Sourdough Discard Pop Tarts. This will help with cleanup later and prevent any sticking during the baking process, allowing for beautiful, golden pastries.
Step 3: Roll Out Dough
On a lightly floured surface, gently roll out the chilled dough to a thickness of about ⅛ inch. Take your time to achieve an even thickness, as it is crucial for consistent baking. Using a sharp knife or pizza cutter, carefully cut the dough into strips, ensuring you have a sufficient number of squares to form the pop tarts. Aim for squares of about 3×4 inches.
Step 4: Fill and Shape
Take each dough strip and spoon 1-2 tablespoons of your chosen jam onto one half of the strip, leaving a small border. Fold the other half of the dough over the filling, creating a pocket. Press the edges firmly with your fingers to seal the pop tart. For an added decorative touch and to ensure a tight seal, use a fork to crimp the edges, making each Sourdough Discard Pop Tart visually appealing.
Step 5: Bake
Brush the tops of the sealed pop tarts with an egg wash made from beaten egg for a golden finish. Carefully place the pastries on the prepared baking sheet and bake in the preheated oven for about 25 minutes. Keep an eye on them, and look for a beautifully golden color to indicate they are done. Allow the pop tarts to cool on a wire rack for about 10 minutes before glazing.
Step 6: Glaze Preparation
While the Sourdough Discard Pop Tarts cool, prepare the glaze. In a mixing bowl, whisk together powdered sugar, lemon juice, and a little water until smooth and pourable. Adjust the consistency as needed by adding more water if it’s too thick. Once the pastries have cooled completely, drizzle the glaze over the pop tarts for a sweet finishing touch.

Expert Tips for Sourdough Discard Pop Tarts
-
Chill the Dough: Always chill your dough for at least an hour. This crucial step helps achieve the flaky texture that makes your sourdough discard pop tarts irresistible.
-
Don’t Overfill: Avoid the temptation to add too much jam, as this can cause spillage during baking. Stick to 1-2 tablespoons to keep the filling intact.
-
Secure the Edges: Use a fork to crimp the edges for both decoration and to ensure a good seal, preventing any filling from leaking out while baking.
-
Cool Before Glazing: Let your pop tarts cool completely before applying the glaze. This avoids melting and ensures a beautiful, shiny finish on your pastries.
-
Experiment with Fillings: Play around with different fillings beyond jam. Nutella, peanut butter, or even fresh fruit slices can create delicious variations of your sourdough discard pop tarts!
