Chocolate Caramel Tart with Sea Salt - "Twix Tart"
makes (1) 9-in tart or (6) 3 1/2-in tartlets
10 tablespoons (5 ounces) unsalted butter, room temperature
1/2 cup (3 1/2 ounces) sugar
2 eggs, room temperature
2 cups (8 1/2 ounces) all purpose flour
1 teaspoon salt
1/2 cup heavy cream
1 cup sugar
pinch of Maldon sea salt
12 ounces bittersweet (60%-66%) chocolate, coarsely chopped
2 cups heavy cream
For the pâte sablée:
Cream butter and sugar together in a stand mixer. Add eggs and mix just until incorporated. Add flour and salt and mix on low just until incorporated.
Scrape out dough onto a piece of plastic wrap and form into a disk. Wrap fully and refrigerate for at least 1 hour or overnight.
Flour work surface and roll out dough to 1/4″ thick. Lay into a 9″ tart pan or tart rings of your choosing and trim excess dough with a knife. Refrigerate for an hour before baking.
Preheat oven to 350 degrees F. Line tart shell with foil and fill with dried beans or pie weights. Bake for 30 minutes (check earlier if you are baking individual tarts), turning halfway through.
Remove foil and weight and bake for 10 more minutes (individual tarts may not need additional baking time). Tart shells should be lightly golden. Remove from oven and let cool fully on wire rack before filling.
For the caramel:
Place cream in a small saucepan and bring to boil. Set aside while you cook the sugar.
Combine sugar with 5 tablespoons of water in a heavy saucepan. Cook over high heat, stirring, until sugar dissolves. Bring mixture to boil and cook without stirring for about 4 minutes until it turns dark amber. Swirl to ensure it cooks evenly.
Take mixture off stove and pour cream slowly into the sugar (it will boil up so don’t pour in all at once.)Stir until incorporated and smooth.Add in salt. If caramel has cooled too much and become thick, place over heat and warm until it is liquid enough to pour.
Pour the caramel into the tart shell, covering the bottom evenly. Let cool until it firms and is no longer shiny. You can place the tart shell in the refrigerator to speed up the process.
For the ganache:
Place chocolate and salt in a heatproof bowl. Place cream in a small saucepan and bring to a boil on high heat on the stove. Pour cream over the chocolate and let sit for a few minutes. Then whisk slowly and gently to combine. Do not stir too vigorously as this incorporates air into the ganache and gives it a less smooth and velvety texture.
Pour the ganache into the tart shell over the caramel. Let set at room temperature for at least 3 hours or up to 12 hours.
Sprinkle with sea salt before serving.
