Benvenuti, fellow food lovers, to another delightful journey with Torta Magica! Today, we're whisking you away to the sun-drenched Amalfi Coast with our exquisite Lemon Mascarpone Tart. This recipe marries the vibrant zest of fresh lemons with the unparalleled creaminess of Italian mascarpone, creating a dessert that is both sophisticated and incredibly comforting.

It's a tart that speaks of elegant simplicity, where each ingredient shines without overpowering the others. The crisp, buttery pâte sablée provides the perfect counterpoint to the silken, tangy filling, making every bite a harmonious blend of textures and flavours. Whether you're entertaining guests or simply treating yourself, this tart is guaranteed to bring a touch of Italian magic to your table.

The Perfect Pâte Sablée Base

A truly exceptional tart begins with an outstanding base, and for this Lemon Mascarpone Tart, we use a classic French-inspired pâte sablée. This 'sandy dough' is rich in butter and often contains icing sugar and egg yolk, which give it a delicate, crumbly texture that melts in your mouth. It's far superior to a standard shortcrust for fruit or creamy fillings, as its fine crumb resists becoming soggy.

To achieve that perfect crumbly tenderness, it's crucial not to overwork the dough; handle it minimally to prevent gluten development, which can lead to a tough crust. Chilling the dough thoroughly, both before rolling and again after lining the tin, is also vital. This relaxes the gluten and firms up the butter, ensuring the pastry holds its shape beautifully during blind baking and doesn't shrink back in the oven.

Mascarpone: The Heart of the Tart

Mascarpone cheese is the star ingredient that elevates this tart from simply good to truly magnificent. Originating from Lombardy, this Italian cream cheese is made from coagulated cream, giving it an incredibly rich, buttery, and velvety texture. Unlike other cream cheeses, mascarpone has a higher fat content and a less tangy flavour, making it an ideal base for sweet desserts where its luxurious mouthfeel can truly shine.

In our lemon tart, mascarpone provides a sublime creaminess that perfectly balances the tartness of the lemon juice. It creates a filling that is smooth, dense, and utterly decadent without being overly heavy. Its mild sweetness allows the bright citrus notes to come through beautifully, resulting in a balanced flavour profile that is both refreshing and deeply satisfying.

Nonna's tip

To prevent your pastry from shrinking during baking, ensure you chill the dough thoroughly before rolling and blind baking. Also, prick the base generously with a fork to allow steam to escape, preventing puffing.

Ingredients
  • 200g (1 ½ cups) plain flour
  • 100g (½ cup) unsalted butter, cold and cubed
  • 50g (¼ cup) icing sugar
  • 1 egg yolk
  • Pinch of salt
  • 250g (1 cup) mascarpone cheese
  • 150g (¾ cup) caster sugar
  • 3 large eggs
  • Zest of 2 large lemons
  • 120ml (½ cup) fresh lemon juice
  • 2 tbsp cornflour
  • 50ml (¼ cup) double cream
Method
  1. To make the pâte sablée, combine the flour, icing sugar, and salt in a large bowl. Add the cold, cubed butter and rub it in with your fingertips until the mixture resembles fine breadcrumbs.

  2. Add the egg yolk and mix until the dough just comes together; if too dry, add a teaspoon of cold water. Form into a disc, wrap in cling film, and chill for at least 30 minutes.

  3. On a lightly floured surface, roll out the chilled dough to a 3mm thickness and carefully line a 23cm fluted tart tin. Trim the edges, prick the base all over with a fork, and chill for another 20 minutes.

  4. Preheat your oven to 180°C (160°C fan/Gas Mark 4). Line the pastry shell with baking parchment and fill with baking beans. Blind bake for 15 minutes, then remove the beans and parchment and bake for another 10 minutes, or until lightly golden.

  5. While the pastry bakes, prepare the filling: In a bowl, whisk together the mascarpone, caster sugar, eggs, lemon zest, lemon juice, cornflour, and double cream until smooth and well combined.

  6. Pour the filling into the pre-baked pastry shell. Carefully return the tart to the oven and bake for 25-30 minutes, or until the filling is set around the edges but still has a slight wobble in the centre.

  7. Remove the tart from the oven and let it cool completely on a wire rack at room temperature, then chill in the refrigerator for at least 2 hours before serving. Dust with icing sugar before slicing.

Good to know

Frequently asked

Why is my pastry soggy at the bottom?

Soggy pastry is often due to insufficient blind baking. Ensure your pastry base is golden and crisp before adding the filling, and consider baking it for a few extra minutes without the beans if it looks pale.

Can I make this tart ahead of time?

Absolutely! This tart is excellent when made a day in advance. The flavours have more time to meld, and the filling sets beautifully, making it perfect for entertaining.

What if my filling cracks after baking?

Cracking can occur if the tart is overbaked or cooled too rapidly. Bake until just set with a slight wobble, then allow it to cool gradually at room temperature before transferring it to the fridge.
