<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Begin with the pastry. In a large bowl, rub the cold cubed butter into the flour until it resembles breadcrumbs (keeping everything cool prevents the butter from melting, which ensures a flaky crust). Stir in the icing sugar and salt, then add the egg yolk and just enough ice water to bring the dough together into a ball. Don't overwork the dough or it will become tough. Wrap in cling film and refrigerate for at least 30 minutes.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>While the pastry chills, preheat your oven to 120°C. Break the white chocolate into small pieces and spread evenly on a baking sheet. Place in the oven and roast for about 45-60 minutes, removing every 10 minutes to stir and redistribute. The chocolate will progress from white to ivory to a gorgeous caramel color. This slow roasting transforms simple white chocolate into a complex, nutty flavor base for your filling. Once it reaches a light caramel color, remove and set aside.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Roll out the chilled pastry on a lightly floured surface to about 3mm thickness and carefully line your tart tin, pressing gently into the fluted edges. Trim the excess, prick the base with a fork, and return to the refrigerator for 15 minutes. This chilling step prevents shrinkage during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Increase the oven temperature to 180°C. Line the chilled pastry case with baking paper and fill with baking beans or rice. Blind bake for 15 minutes, then remove the paper and beans and bake for a further 5-10 minutes until the base is lightly golden and cooked through. Set aside to cool while you prepare the fillings.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>For the roasted white chocolate filling, heat the cream in a saucepan until just simmering. Remove from heat and add the roasted white chocolate, butter, and vanilla. Stir until smooth and velvety. In a separate bowl, whisk the egg yolks with the caster sugar until pale. Gradually pour the warm chocolate mixture into the egg mixture, whisking constantly to prevent scrambling (this is called tempering the eggs). Return the mixture to the saucepan and cook over low heat, stirring constantly, until it thickens enough to coat the back of a spoon (about 82-84°C on a digital thermometer).</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Strain the white chocolate custard through a fine mesh sieve into a clean bowl to ensure a silky-smooth texture. Pour into the cooled tart shell, leaving about 1cm space at the top for the passion fruit layer. Refrigerate for at least 2 hours until set firm.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>For the passion fruit layer, cut open the passion fruits and pass the pulp through a sieve into a measuring jug to remove the seeds (you'll need about 120ml of juice). In a saucepan, whisk together the passion fruit juice, sugar, cornflour, eggs, and egg yolk until smooth. Cook over medium heat, whisking constantly, until the mixture thickens and begins to bubble. Remove from heat and whisk in the butter pieces until fully incorporated. The acid in the passion fruit works with the eggs to create a natural thickening reaction.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the passion fruit curd to cool slightly before spreading it carefully over the set white chocolate layer. Smooth the top with an offset spatula, then refrigerate for at least 4 hours or overnight to set completely. The distinct layers need proper setting time to ensure they don't blend together.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>For the mirror glaze, sprinkle the gelatin over the cold water in a small bowl and let it bloom for 5-10 minutes. In a medium saucepan, combine the sugar, glucose, and water and bring to a boil until it reaches 103°C. Remove from heat and stir in the bloomed gelatin until dissolved. Add the chopped white chocolate and condensed milk, then use an immersion blender to blend until completely smooth, avoiding air bubbles which would mar the mirror finish.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Divide the glaze into two portions. Color one portion yellow and the other orange, then combine them partially for a marbled effect. Allow the glaze to cool to 35-38°C before using – this is the critical temperature range where the glaze is fluid enough to pour but not so hot that it will melt your filling.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Remove the set pie from the refrigerator and place it on a wire rack set over a baking sheet to catch the excess glaze. Pour the glaze evenly over the pie, starting from the center and moving outward in a circular motion. The glaze should flow naturally to the edges and over the sides. If needed, use an offset spatula to help guide it. The gelatin in the glaze sets quickly on contact with the cold pie, creating that signature mirror-like finish.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Carefully transfer the glazed pie back to the refrigerator and chill for at least 30 minutes to set the glaze completely. Once set, gently remove the pie from the tart tin and transfer to a serving plate. If desired, decorate with gold leaf, fresh passion fruit halves, and white chocolate shavings for an elegant finishing touch.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>For the best texture and flavor contrast, allow the pie to come to room temperature for about 20 minutes before serving. The pie will keep in the refrigerator for up to 3 days, though the mirror glaze may lose some of its shine over time. Each slice should reveal beautiful distinct layers: the crisp pastry, creamy roasted white chocolate, tangy passion fruit, and the glossy mirror glaze – a truly show-stopping dessert worth every minute of preparation!</li></ol>
