🥧 Make the Tart Crust:

1. Prepare the Dough:

   • In a food processor, combine flour, sugar, and salt.
   • Add the cold butter and pulse until the mixture resembles coarse crumbs.
   • Add the egg yolk and 1 tablespoon of cold water, pulsing until the dough just comes together. Add more water if needed.

2. Chill the Dough:

   • Shape the dough into a disc, wrap in plastic wrap, and refrigerate for 30 minutes.

3. Bake the Tart Shells:

   • Preheat your oven to 180°C (350°F).
   • Roll out the dough and press into 6 small tart pans or 1 large 9-inch tart pan.
   • Prick the base with a fork, line with parchment paper, and fill with pie weights or dried beans.
   • Bake for 15 minutes, then remove weights and bake for an additional 5-7 minutes until golden.
   • Let cool completely.

🍮 Make the Salted Caramel Filling:

1. Melt the Sugar:

   • In a medium saucepan over medium heat, melt the sugar, stirring occasionally.
   • Cook until the sugar turns a deep amber color.

2. Add Butter and Cream:

   • Carefully whisk in butter until fully melted.
   • Slowly add the heavy cream while stirring continuously (the mixture will bubble vigorously).

3. Add Vanilla and Salt:

   • Stir in vanilla extract and sea salt until smooth.
   • Pour the caramel into the cooled tart shells, filling them about halfway.
   • Refrigerate for 30 minutes to set.

🍫 Prepare the Chocolate Ganache:

1. Heat the Cream:

   • In a small saucepan, heat the heavy cream until it just begins to simmer (do not boil).

2. Melt the Chocolate:

   • Pour the hot cream over the chopped chocolate in a bowl.
   • Let sit for 2-3 minutes, then stir until smooth and glossy.
   • Mix in the butter until combined.

3. Fill the Tarts:

   • Pour the ganache over the set caramel layer in the tart shells.
   • Smooth the top with a spatula and refrigerate until set (about 1 hour).

🍽️ Serve:

1. Garnish:

   • Sprinkle with flaky sea salt and garnish with chocolate shavings or a light dusting of cocoa powder.

2. Serving Suggestions:

   • These tarts are best served chilled or at room temperature. Pair with fresh berries or a scoop of vanilla ice cream for an extra treat!
