Ingredients
200 gall-purpose flour
100 gcold butter
2 pinchsalt
1 pieceegg yolk
30 mlice water
150 mlfresh lemon juice
3 pieceslemon zest
3 pieceseggs
150 ggranulated sugar
50 gbutter
20 gpowdered sugar
Instructions
1MAKE THE PASTRY DOUGH: In a large bowl, combine 200g flour and a pinch of salt, then cut in 100g cold butter into small cubes using your fingertips until the mixture resembles coarse breadcrumbs with pea-sized butter pieces remaining. Add 1 egg yolk and 30ml ice water, mixing gently with a fork until the dough just comes together without overworking it. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes to allow the gluten to relax and the butter to firm up, which will prevent shrinkage during baking.
2PREPARE THE TART SHELL: Preheat your oven to 200°C (400°F). Remove the chilled dough from the refrigerator and roll it out between two sheets of parchment paper to a thickness of about 3mm, slightly larger than your 9-inch tart pan. Transfer the dough to the tart pan, pressing it gently into the corners and sides, then trim any excess with a knife. Line the shell with parchment paper and fill with dried beans or pie weights to prevent puffing, then blind-bake for 15 minutes until the edges are lightly golden.
3REMOVE WEIGHTS AND CONTINUE BAKING: Carefully remove the parchment paper and weights from the tart shell after the 15-minute blind bake, watching for any cracks or soft spots. Return the shell to the oven for an additional 5-7 minutes until the bottom is pale golden and feels set when touched lightly. Remove from the oven and reduce the oven temperature to 160°C (320°F) to prepare for baking the delicate lemon filling.
4PREPARE THE LEMON CUSTARD FILLING: In a medium saucepan, whisk together 3 whole eggs and 150g granulated sugar until pale and slightly thickened, about 2-3 minutes of continuous whisking. Pour in 150ml fresh lemon juice and add the zest from 3 lemons, stirring well to combine and ensure the zest is evenly distributed throughout the mixture. Place the saucepan over medium-low heat and cook, stirring constantly with a wooden spoon, until the mixture reaches 70°C (158°F) on a cooking thermometer, about 8-10 minutes, which pasteurizes the eggs and creates a thick custard consistency.
5FINISH THE FILLING AND STRAIN: Remove the lemon custard from the heat and stir in 50g cold butter, cut into small pieces, allowing it to melt and incorporate smoothly for a silky texture. Pour the filling through a fine-mesh sieve into a clean bowl, pressing gently with the back of a spoon to remove any bits of cooked egg white or lemon pulp, resulting in a perfectly smooth, glossy filling. This step is crucial for achieving the refined texture characteristic of a professional-quality lemon tart.
6BAKE THE TART AND COOL: Carefully pour the smooth lemon custard filling into the pre-baked tart shell, filling it almost to the brim, and place in the 160°C oven for 12-15 minutes until the filling is just set but still has a very slight jiggle in the center when gently shaken. The filling will continue to set as it cools due to residual heat, so remove it from the oven before it appears completely firm to avoid overcooking. Allow the tart to cool completely at room temperature for at least 1 hour, then refrigerate for at least 2 hours before serving to allow the filling to firm up completely and develop its full flavor.
7SERVE AND GARNISH: Remove the tart from the refrigerator 10-15 minutes before serving to allow it to reach a pleasant, slightly cool temperature that highlights the bright lemon flavor. Dust the top lightly with 20g powdered sugar using a fine sieve for an elegant presentation, then slice with a sharp, hot knife dipped in hot water and wiped clean between cuts to prevent the filling from sticking. Serve with fresh whipped cream, crème fraîche, or vanilla ice cream to complement the tartness of the lemon custard.
