Ingredients:
- 1 1/4 cups (150g) all-purpose flour, plus extra for dusting
- 1/2 cup (113g, 1 stick) unsalted butter, very cold and cut into cubes
- 1/4 cup (60ml) powdered sugar (icing sugar)
- 1 large egg yolk
- 2-3 tablespoons (30-45ml) ice water
- 1 cup (200g) granulated sugar
- 1/4 cup (30g) all-purpose flour
- 1/4 teaspoon salt
- 3 large eggs
- 1/2 cup (120ml) freshly squeezed lemon juice (from about 3-4 lemons)
- 1/4 cup (57g, 1/2 stick) unsalted butter, cut into cubes
- 1 tablespoon lemon zest
- Powdered sugar (icing sugar), for dusting
- Fresh raspberries or mint leaves
Instructions:
- Combine flour, butter, and powdered sugar in a food processor (or by hand). Pulse/rub together until it resembles coarse breadcrumbs.
- Add egg yolk and ice water. Pulse/mix until the dough just comes together. Don't overmix!
- Form the dough into a disc, wrap it in plastic wrap, and chill for at least 30 minutes.
- Roll out the dough on a lightly floured surface.
- Cut out circles slightly larger than the muffin tin cups.
- Press the dough circles into the muffin tin cups, gently pressing them into the edges.
- Prick the bottom of each tart shell with a fork.
- Whisk together sugar, flour, and salt in a saucepan.
- Whisk in eggs, lemon juice, and lemon zest.
- Add butter and cook over medium-low heat, stirring constantly, until the mixture thickens and coats the back of a spoon (about 5-7 minutes).
- Pour the lemon filling into the prepared tart shells.
- Bake in a preheated oven (350°F/175°C) for 20-25 minutes, or until the crust is golden brown and the filling is set but still slightly wobbly.
- Let the tarts cool completely in the muffin tin before gently removing them.
- Dust with powdered sugar and garnish with raspberries or mint, if desired.
