Instructions

1. Preheat the oven to 180°C (350°F). Apply a light coating of butter to a tart tin to prevent the pastry from sticking.
2. Unfold the shortcrust pastry onto a lightly floured surface. Carefully roll out the pastry to fit the tart tin. Line the tin with the pastry, pressing it gently into the corners. Trim off any excess pastry hanging over the edges.
3. To prepare the filling, whisk together the lemon juice, lemon zest, melted butter, sugar, and eggs in a medium-sized bowl until you achieve a smooth consistency.
4. Pour the lemon mixture carefully into the pastry-lined tart tin, ensuring it's evenly spread.
5. Bake in the preheated oven for approximately 25 minutes. The tart is done when the filling is set and the pastry has turned a golden-brown color.
6. Allow the tart to cool in the tin for about 15 minutes. This ensures it holds its shape when you remove it from the tin. Serve at room temperature for the best flavor.
