Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Begin by making the pastry. Place the flour, salt and butter in a food processor and pulse until the mixture resembles fine breadcrumbs. This cold butter technique is crucial – it creates pockets of fat that will make your pastry flaky when baked. Alternatively, rub the ingredients together with your fingertips, being careful not to warm the butter too much.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the icing sugar and pulse briefly to combine. Beat the egg yolk with 2 tablespoons of ice-cold water, then drizzle into the processor while pulsing until the dough just starts to come together. Only add the final tablespoon of water if necessary – too much moisture will result in tough pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Tip the dough onto a lightly floured surface and gently bring together into a disc without kneading (which would develop gluten and make the pastry tough). Wrap in cling film and chill for at least 30 minutes – this relaxes the gluten and firms up the butter, preventing pastry shrinkage during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Preheat your oven to 190°C (170°C fan). Roll out the chilled pastry on a floured surface to about 3-4mm thickness, creating a circle large enough to line your tart tin with some overhang. Work quickly to keep the pastry cool. Carefully drape the pastry over your rolling pin and transfer to the tin, pressing it gently into the corners without stretching it.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Trim the excess pastry, leaving a slight overhang to allow for shrinkage. Prick the base with a fork, then chill for another 15 minutes. Line the pastry case with baking parchment and fill with baking beans or dried rice. Blind bake for 15 minutes, then remove the beans and parchment and bake for a further 5-7 minutes until the base is dry and pale golden. The initial blind baking prevents the dreaded "soggy bottom" by creating a moisture barrier.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>While the pastry case cools slightly, reduce the oven temperature to 160°C (140°C fan) and prepare your filling. In a large bowl, whisk together the light and dark brown sugars with the eggs until well combined but not too aerated – we want a smooth custard without air bubbles.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Gently heat the cream and milk in a saucepan until just below simmering point – you'll see tiny bubbles around the edge. Remove from heat and slowly pour into the egg mixture, whisking constantly. This gradual tempering prevents the eggs from curdling while incorporating the warm dairy.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Add the vanilla extract, freshly grated nutmeg, and a pinch of salt, then stir to combine. Pour the mixture through a fine-mesh sieve into a jug to remove any egg strands or impurities, ensuring your custard will be silky smooth.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Place your pastry case (still in its tin) on a baking sheet positioned on the middle rack of the oven. Carefully pour the strained custard into the pastry case, filling it almost to the top. This oven-shelf filling technique minimizes the risk of spills while transferring to the oven.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Bake for 25-30 minutes until the custard is just set but still has a slight wobble in the center – like a barely set jelly. The center should reach about 75°C if you have a thermometer. Don't overbake or the texture will become grainy rather than silky. The custard will continue to set as it cools.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Allow the tart to cool completely in its tin on a wire rack – this will take about 2 hours. The cooling process is crucial for the custard to fully set and develop its flavors. Once cooled, trim any remaining pastry overhang with a sharp knife for a clean edge.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Carefully remove the tart from the tin and transfer to a serving plate. For the best flavor and texture, serve at room temperature. The tart will keep in the refrigerator for up to 3 days, though the pastry will soften slightly over time. Bring back to room temperature before serving for the optimal custard texture.</li></ol>
