👨‍🍳 Instructions

1. 1--- Prepare the crust ---
2. 2Cream the butter and powdered sugar until smooth (but don't aerate it). 100 g unsalted butter, 90 g powdered sugar
3. 3Beat in the egg until combined. 1 large egg
4. 4Add the flour and salt, mix until the dough just comes together. Shape into a disc, wrap, and chill for at least 30 minutes. 220 g all-purpose flour, ¼ tsp salt
5. 5Roll the pâte sucrée out to 3-4mm thick and fit it into a 9-10 inch tart pan with a removable bottom. Trim the edges, dock the base with a fork, and chill for 20-30 minutes.
6. 6Preheat your oven to 340°F (170°C).
7. 7Line the chilled tart shell with parchment paper and fill with pie weights or dried beans. Bake for 20 minutes.
8. 8Remove the parchment and weights. Bake for another 15-20 minutes until the crust is golden brown all over. Let it cool completely.
9. 9--- Make the lemon filling ---
10. 10Add the egg yolks to a medium bowl and whisk them together by hand. Set aside. Save two of the remaining egg whites in the fridge for the meringue. 4 large egg yolks
11. 11Whisk water, sugar, lemon juice, cornstarch, salt, and lemon zest in a medium saucepan over medium heat. Let it boil, whisking regularly until it becomes thick and glossy. 240 g water, 200 g granulated sugar, 30 g cornstarch, 1/8 tsp salt, 120 g lemon juice, 1 Tbsp lemon zest
12. 12Take it off the heat, drizzle in a bit at a time of the hot mixture into the egg mixture, whisking while you do. Once the egg yolks have warmed, add everything back into the saucepan and place it over medium heat.
13. 13Cook until the mixture is thick and boiling again, whisking continuously.
14. 14Remove it from the heat and stir through the butter until completely melted and smooth. 28 g butter
15. 15Pour the hot lemon filling into the cooled tart shell. Smooth the top with a spatula.
16. 16Optionally, press a piece of plastic wrap directly onto the surface of the filling to prevent a skin from forming.
17. 17Refrigerate for at least 3 hours, or until the filling is completely set and firm.
18. 18--- Make the Swiss meringue ---
19. 19Combine egg whites and sugar in a heatproof metal bowl. 2 large egg whites, 100 g granulated sugar
20. 20Place the bowl over a saucepan of simmering water, making sure the bottom doesn't touch the water.
21. 21Whisk constantly until the sugar has completely dissolved and the mixture reaches 160°F (71°C) on a thermometer. This takes about 3-5 minutes. The mixture should feel smooth when rubbed between your fingers, with no grittiness from the sugar.
22. 22Transfer the bowl to your stand mixer fitted with the whisk attachment (or use a hand mixer).
23. 23Whip on high speed until stiff, glossy peaks form and the bowl is cool to the touch. Add the salt in the last minute of whipping. Tiny pinch of salt
24. 24Remove the plastic wrap from the chilled tart. Spread or pipe the meringue over the lemon filling, creating peaks and swirls.
25. 25Use a kitchen torch to toast the meringue until golden brown. Alternatively, place under the broiler for 1-2 minutes, watching carefully so it doesn't burn.
26. 26Serve immediately or refrigerate until ready to serve.
