Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>For the pastry, combine flour and salt in a large bowl or food processor. Add the cold cubed butter and pulse or use your fingertips to work it in until the mixture resembles coarse breadcrumbs with some pea-sized butter pieces remaining. These butter pieces are crucial for creating flaky layers in your pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Mix the apple cider vinegar with ice-cold water. The vinegar helps inhibit gluten formation, ensuring a tender crust. Add this liquid gradually to the flour mixture, stirring with a fork until the dough just comes together. Be careful not to overwork it.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Turn the dough onto a lightly floured surface and gently form it into a disk. Wrap in plastic film and refrigerate for at least 1 hour. Cold dough is easier to handle and produces flakier results as the butter remains solid until hitting the hot oven.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>While the dough chills, prepare your filling. Clean and finely chop the mushrooms. Different varieties will add complexity to the flavor profile—portobellos bring meatiness, shiitakes add umami notes, and cremini provide earthiness.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Heat olive oil in a large skillet over medium heat. Add onions and sauté until soft and translucent, about 5-7 minutes. Add garlic and cook for another minute until fragrant.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Increase heat to medium-high and add mushrooms, thyme, and rosemary. Cook, stirring occasionally, until mushrooms have released their moisture and it has evaporated, about 10-12 minutes. This concentration of flavors is key to avoiding soggy pies.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Add white wine and scrape up any browned bits from the bottom of the pan—these contain concentrated flavor. Allow the liquid to reduce completely, then remove from heat and stir in the crème fraîche and Parmesan. Season generously with salt and pepper, then allow the mixture to cool completely.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Preheat your oven to 200°C and line a baking sheet with parchment paper. Remove the dough from the refrigerator and let it sit for 5-10 minutes to slightly soften, making it easier to roll.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>On a floured surface, roll the dough to about 3mm thickness. Cut out eight 15cm circles (use a bowl or plate as a guide). Gather scraps, re-roll, and cut more circles if needed.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Place about 2 tablespoons of mushroom filling slightly off-center on each dough circle, leaving a 1.5cm border. Brush the edges lightly with water, then fold the dough over to create a half-moon shape. Press the edges firmly to seal, then crimp with a fork or create a decorative edge by folding and pinching.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Transfer pies to the prepared baking sheet. Cut a small vent in the top of each pie to allow steam to escape during baking. Beat the egg with a teaspoon of water and brush the tops of the pies for a gorgeous golden finish.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Bake for 22-25 minutes until deeply golden brown. The perfect pie will have a crisp, flaky exterior and should sound hollow when tapped on the bottom. Allow to cool for 5-10 minutes before serving—the filling will be extremely hot!</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Serve warm or at room temperature. These pies will keep for 3 days refrigerated or can be frozen for up to 3 months. To reheat, place in a 180°C oven for 10-15 minutes until warmed through and crisp again.</li></ol>
