Method
Make the tart shell
- Pulse all-purpose flour, powdered sugar, salt, and cold butter until the mixture looks like fine crumbs. Add egg yolk and cold water and pulse just until the dough comes together.
- Press the dough into a 9-inch tart pan, pressing evenly into the bottom and up the sides. Chill for 30 minutes to firm the crust.
- Blind bake at 375°F for 18-20 minutes, until the shell is golden. Cool completely so the filling won’t melt into the crust.
Make the lemon cream filling
- Whisk eggs, granulated sugar, fresh lemon juice, and lemon zest in a saucepan over medium heat. Stir constantly for 8-10 minutes until thick enough to coat the back of a spoon and the surface looks smooth.
- Remove from the heat and strain through a fine sieve. Whisk in cold butter cubes one at a time until fully melted, smooth, and glossy.
- Pour the lemon cream into the cooled tart shell and smooth the top. Refrigerate for 3 hours until set and wobble-free in the center.
Brûlée and garnish
- Before serving, sprinkle 2 tablespoons sugar evenly over the surface. Brûlée with a kitchen torch until amber and crackled.
- Garnish with lemon zest curls right after brûlée so they look bright. Slice and serve immediately while the sugar crust shatters.
Notes
Pro tip: strain the lemon custard to eliminate any bits before butter incorporation for that gleaming, ultra-smooth finish. Store the tart (without the brûlée) covered in the refrigerator up to 3 days. Freeze the unbrûléed tart up to 1 month; thaw in the fridge, then brûlée fresh. For a dietary swap, you can use unsalted butter throughout and reduce added sugar slightly (about 2-3 tbsp) while keeping the thickness cook time the same.
