Preparation Steps

Step 1: Prepare the Pastry Base

Start by combining pastry flour and icing sugar in a large mixing bowl. Add the unsalted butter and mix until the texture resembles coarse crumbs. This step can be done by hand or using a food processor for convenience. Add the egg yolk and vanilla extract then continue mixing until the dough begins to come together.

Once the dough has formed, wrap it in plastic and refrigerate for about 30 minutes to allow it to firm up. This creates a flaky texture when baked, a signature of a well-made tart base.

Step 2: Bake the Tart Shell

Preheat your oven to 350°F (175°C). Roll out the chilled dough on a lightly floured surface to fit a 9-inch tart pan. Gently press the dough into the pan, ensuring there are no air bubbles, and trim the excess.

Use a fork to prick the base of the tart lightly, which prevents bubbling during baking. Line the shell with parchment paper, fill with baking weights or beans, and bake for about 15 minutes. Remove the weights and parchment, then bake for another 10 minutes until golden brown. Allow it to cool completely on a wire rack.

Step 3: Making the Lime Filling

In a medium saucepan, combine the condensed milk and lime juice. Stir over low heat until well combined. In a small bowl, sprinkle the gelatin over 1/4 cup cold water and let it soften for about 5 minutes.

Once the gelatin has bloomed, add it to the lime mixture and continue stirring until completely dissolved. Remove the pan from heat and let the mixture cool slightly.

Step 4: Whip the Cream

Pour whipping cream into a chilled bowl and beat until soft peaks form. Gradually add icing sugar while continuing to whip until stiff peaks form. Gently fold the whipped cream into the lime mixture, reserving about 1/2 cup for garnish.

Step 5: Assemble the Tart

Pour the lime and cream mixture into the cooled tart shell, spreading it evenly. Refrigerate the tart for at least 4 hours, or until the filling is set. Before serving, use the reserved whipped cream to pipe decorative patterns on the surface of the tart. Optionally, top with fresh berries for a burst of color and tartness.

Cooking Time

The total cooking time for this recipe, including preparation and chilling, is approximately 5 hours. Most of this time involves passive chilling to ensure the filling sets properly.
