Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Chill all your ingredients before starting. Place the gluten-free flour, almond flour, salt, and sugar (if using) in a food processor. If your gluten-free blend doesn't contain xanthan gum, add it now. Pulse briefly to combine. Cold ingredients are crucial for a flaky crust as they prevent the butter from melting too quickly into the flour.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the cold cubed butter to the food processor. Pulse in short bursts until the mixture resembles coarse breadcrumbs with some pea-sized butter pieces still visible. These butter pieces will create steam pockets during baking, resulting in those desirable flaky layers.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Whisk the egg with the apple cider vinegar in a small bowl. The vinegar helps tenderize the dough by inhibiting gluten-like protein bonds that can form even in gluten-free flours. With the processor running, pour this mixture through the feed tube.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add ice water, one tablespoon at a time, pulsing between additions, until the dough just begins to come together when pressed between your fingers. Gluten-free pastry often needs slightly more moisture than wheat-based dough, but be careful not to add too much water or your crust will become tough.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Turn the dough onto a piece of plastic wrap, shape into a disc without overworking, and wrap tightly. Chill for at least 1 hour or up to 2 days. This resting period allows the flours to fully hydrate and the butter to firm up again, making the dough easier to roll.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>When ready to roll, let the dough sit at room temperature for 10-15 minutes to soften slightly. Dust your work surface and rolling pin with gluten-free flour. Place the disc between two sheets of parchment paper to prevent sticking and make transferring easier.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Roll the dough outward from the center in all directions to form a circle about 3mm thick and 30cm in diameter. If the dough cracks (common with gluten-free pastry), simply press it back together with your fingertips—this forgiving nature is one advantage of gluten-free dough!</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Remove the top sheet of parchment and carefully invert the dough over your pie dish. Gently ease it into the corners without stretching. Trim the excess dough leaving a 2cm overhang, then fold this under and crimp the edges decoratively.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>For a blind-baked crust (partially or fully baked before adding filling), prick the bottom several times with a fork to prevent bubbling. Chill for 30 minutes to set the shape and prevent shrinkage.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Preheat your oven to 190°C (375°F). Line the chilled crust with parchment paper and fill with baking beans or weights. Bake for 15 minutes, then remove the weights and parchment.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>For a fully baked crust, continue baking uncovered for 10-12 minutes more until golden brown. For a partially baked crust (to be filled and baked further), bake for just 5-7 minutes more until set but not fully browned. Cool completely before filling.</li></ol>
