<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Begin the spice infusion 72 hours before you plan to serve the tarts. In a medium saucepan, combine the milk and cream. Add all the spices (cinnamon sticks, crushed cardamom pods, star anise, split vanilla bean, cloves, and nutmeg) along with the orange zest strips. Heat the mixture over medium heat until it just reaches a simmer (about 82°C) – you'll see small bubbles forming around the edges. Remove from heat immediately to prevent the milk from boiling over or scorching.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Transfer the hot mixture to a clean glass container with an airtight lid. Allow it to cool to room temperature before sealing. Refrigerate for 72 hours, giving the container a gentle shake once a day. This long, slow infusion allows the spices to fully release their essential oils and flavors into the dairy, creating a deeply complex custard base that simply cannot be rushed.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>On the day of baking, prepare your pastry. In a food processor (or by hand using a pastry cutter), combine the flour, icing sugar, and salt. Add the cold cubed butter and pulse until the mixture resembles fine breadcrumbs – having varied-sized butter pieces creates flaky layers in your finished pastry. Add the egg and pulse just until combined, then add ice water one tablespoon at a time until the dough just comes together. The cold ingredients and minimal handling prevent gluten development, ensuring a tender crust.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Form the dough into a disk, wrap in plastic wrap and refrigerate for at least 30 minutes. This resting period allows the gluten to relax and the butter to firm up, making the dough easier to roll and preventing shrinkage during baking. While waiting, preheat your oven to 180°C (fan 160°C) and place a baking sheet inside to heat up.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Roll out the chilled pastry on a lightly floured surface to about 3mm thickness. Cut circles slightly larger than your tart tins and gently press the pastry into each tin, ensuring it fits into the corners without stretching (which would cause shrinkage). Trim any excess and prick the bases with a fork. Return the lined tins to the refrigerator for 15 minutes to firm up – this cold pastry will maintain its shape better during blind baking.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Line each chilled tart shell with parchment paper and fill with baking beans or pie weights. Place the tins on the preheated baking sheet (the hot surface jumpstarts the cooking of the pastry base, preventing a soggy bottom) and blind bake for 15 minutes. Remove the paper and weights, then bake for an additional 5-7 minutes until the shells are golden and completely dry to the touch. Set aside to cool completely.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Now, finish preparing the custard. Remove the spice-infused milk mixture from the refrigerator and reheat gently until warm but not boiling. Strain through a fine-mesh sieve into a clean saucepan, pressing gently on the spices to extract maximum flavor. Discard the solids.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>In a large heatproof bowl, whisk together the egg yolks, sugar, cornstarch, and salt until pale and slightly thickened. The sugar crystals create micro-tears in the egg yolks, helping to break them down for a smoother custard. Gradually whisk in the warm strained milk mixture in a slow, steady stream to temper the eggs without scrambling them.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Return the entire mixture to the saucepan and cook over medium-low heat, whisking constantly (be sure to reach the corners of the pan where custard can catch first). Continue cooking until the custard thickens enough to coat the back of a spoon and reaches 82-85°C on a digital thermometer. This temperature perfectly sets the eggs without curdling them. The mixture will seem thin at first but will thicken dramatically as the cornstarch activates.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Once thickened, immediately strain the custard through a clean fine-mesh sieve into a bowl to remove any potential lumps. Cover the surface directly with plastic wrap (touching the custard) to prevent a skin from forming. Allow to cool for about 15 minutes so it's still warm but won't melt the pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Fill each cooled tart shell with the warm custard, stopping just below the rim. Gently tap each filled tart to remove any air bubbles. Allow the tarts to cool to room temperature, then refrigerate for at least 2 hours until the custard is completely set.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Just before serving, grate a light dusting of fresh nutmeg over each tart. The warm, gentle spice will complement the complex flavors that developed during the 72-hour infusion. Serve the tarts cool but not cold from the refrigerator to allow the full spectrum of spice flavors to shine – about 15 minutes at room temperature is perfect for the optimal creamy texture and aromatic experience.</li></ol>
