Chocolate Truffle Tarts

I am in the process of making a Chocolate Truffle Tart for a friends' birthday tomorrow.

While I am not the biggest chocolate fan, I do actually enjoy experimenting with recipes that call for chocolate.  Chocolate desserts seem to have a way of always pleasing chocoholics no matter how mediocre they actually are.

I am pretty sure this tart will be delightful though, I mean, it's a truffle in tart form.  What's not to love about that?

Chocolate Truffle Tart

Yield: about 10-12 servings

INGREDIENTS

For the tart shell:
1 large egg yolk
1 tbsp. heavy cream
½ tsp. vanilla extract
1 cup (5 oz.) all-purpose flour, plus more for dusting the work surface
¼ cup (¾ oz.) Dutch-process cocoa powder
2/3 cup (2 2/3 oz.) confectioners’ sugar
¼ tsp. salt
8 tbsp. cold unsalted butter, cut into ½-inch cubes

For the filling:
12 oz. good quality bittersweet chocolate, finely chopped
6 tbsp. unsalted butter, softened
1 cup heavy cream
1 tbsp. liqueur, such as Kahlua, brandy, or dark rum (optional)  *I just used vanilla

DIRECTIONS

• To make the tart shell, whisk together the egg yolk, cream and vanilla in a small bowl; set aside.  Place the flour, cocoa powder, sugar, and salt in a food processor.  Process briefly to combine.  Scatter the butter pieces over the flour mixture; process to cut the butter into the flour until the mixture resembles coarse meal, about fifteen 1-second pulses.  With the machine running, add the egg mixture and process until the dough just comes together, about 12 seconds.  Turn the dough onto a sheet of plastic wrap and press into a 6-inch dish.  Wrap in plastic wrap and refrigerate at least 1 hour or up to 48 hours.
• Remove the dough from the refrigerator.  (If refrigerated for more than an hour, let stand at room temperature until malleable.)  Unwrap and roll the dough out on a lightly floured surface to a 13-inch round.  Transfer the dough to a 9-inch tart pan.  Mold the dough to the sides of the tart pan and remove the excess off the top.  Set the dough-lined tart pan on a large plate and freeze for 30 minutes.
• Meanwhile, adjust an oven rack to middle position.  Preheat the oven to 375° F.  Set the dough-lined tart pan on a baking sheet, press a 12-inch square of foil into the frozen shell and over the edge, and fill with pie weights.  Bake for 30 minutes, rotating halfway through the baking time.  Remove from the oven and carefully remove the foil and weights.  Continue to bake until just set, 5-8 minutes longer.  Transfer to a wire rack to cool.
• To make the tart filling, place the chocolate and butter in a heatproof bowl.  Bring the cream to a simmer in a small saucepan (or in the microwave).  Pour the hot cream over the chopped chocolate and let stand 1-2 minutes to melt.  Whisk together until smooth, then whisk in the liqueur.  Pour the filling into the tart shell and chill in the refrigerator, uncovered, until the filling is firm.  To serve, transfer the tart to a serving plate or platter.  Slice with a clean, sharp knife, wiping the blade between slices.
