Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Start by preparing the pie dough. In a large bowl, whisk together the flour, salt, and sugar. Add the cold cubed butter and use a pastry cutter or your fingertips to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining. The varying butter sizes create layers in your crust - smaller pieces for tenderness and larger pieces for flakiness.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Combine the ice water and apple cider vinegar in a measuring cup. Drizzle 120ml of this mixture over the flour mixture and gently stir with a fork until the dough begins to come together. If needed, add more water 1 tablespoon at a time. The dough should hold together when squeezed but shouldn't feel wet or sticky.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Divide the dough into two portions, one slightly larger (about 60% of dough for the bottom crust). Form each into a flat disc, wrap tightly in plastic wrap, and refrigerate for at least 2 hours, or ideally overnight. This resting period allows the gluten to relax and the butter to firm up, resulting in a flakier crust.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>While the dough chills, prepare the filling. In a large bowl, gently toss the huckleberries with both sugars, cornstarch, lemon juice, lemon zest, cinnamon, and salt. Let the mixture sit for 15-20 minutes to allow the berries to release some juices. This helps the cornstarch activate before baking, preventing a runny filling.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Preheat your oven to 200°C (400°F) with a rack in the lower third position. Place a baking sheet on the rack to preheat as well - this helps the bottom crust cook properly.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Remove the larger disc of dough from the refrigerator and let it sit for 5-10 minutes to slightly soften. On a lightly floured surface, roll the dough out to a 33cm (13-inch) circle, about 3mm thick. Keep rotating the dough as you roll to prevent sticking and maintain a circular shape.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Carefully transfer the rolled dough to your pie dish by draping it over your rolling pin. Gently press it into the bottom and sides of the dish without stretching the dough (stretching causes shrinkage during baking). Trim the overhang to about 2.5cm (1 inch) beyond the rim.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Pour the huckleberry filling into the dough-lined pie dish, mounding it slightly toward the center. Place the filled pie shell in the refrigerator while you prepare the lattice top.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Roll out the second disc of dough to a 30cm (12-inch) circle. Using a pastry wheel or sharp knife, cut the dough into 2.5cm (1-inch) wide strips for the lattice. Remove the filled pie from the refrigerator and arrange half the strips over the filling in one direction, spacing them evenly.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Fold back every other strip halfway and place one long strip perpendicular across the unfolded strips. Unfold the folded strips over the perpendicular strip. Now fold back the alternate strips and place another perpendicular strip. Continue this process, weaving the lattice pattern over the entire pie. Trim and crimp the edges decoratively.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Brush the lattice top with egg wash and sprinkle generously with demerara sugar. The egg wash creates a beautiful golden sheen, while the sugar adds a delightful crunch and sparkle.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Place the pie on the preheated baking sheet and bake at 200°C (400°F) for 20 minutes. This initial high heat helps set the crust structure. Then reduce the temperature to 175°C (350°F) and continue baking for 35-40 minutes more, or until the filling is bubbling vigorously and the crust is a deep golden brown. Cover the edges with a pie shield or foil if they're browning too quickly.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Transfer the pie to a wire rack and let it cool completely, at least 3-4 hours before slicing. This cooling period is crucial - it allows the filling to set properly. A pie cut too soon will be runny and messy. As it cools, the natural pectin in the berries and the cornstarch will thicken the filling to the perfect consistency.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>Serve at room temperature with a scoop of vanilla ice cream if desired. Store any leftovers covered at room temperature for up to 2 days, or refrigerate for longer storage.</li></ol>
