Kirsch brings out the sweet, juicy flavor of fresh Bing cherries in this sophisticated tart. Martha made this recipe on episode 611 of Martha Bakes.
Turn out dough onto a lightly floured work surface. Roll out to a 12-inch round, a bit less than 1/4 inch thick; fit in a 9-inch fluted tart pan with a removable bottom. Freeze until firm, about 15 minutes.
Preheat oven to 375 degrees. Line shell with parchment paper, leaving a 1-inch overhang. Fill with pie weights. Bake for about 20 minutes. Remove parchment and weights. Bake until golden brown, 10 to 12 minutes more. Transfer to a wire rack and let cool completely.
Whisk together sugar, cornstarch, and salt in a medium saucepan. Whisk together milk and egg yolks in a glass measuring cup. Add milk mixture to the saucepan, along with butter. Cook over medium heat until mixture comes to a boil. Let boil 1 minute. Remove from heat and add vanilla.
Strain pastry cream through a fine-mesh sieve into a bowl and immediately whisk in 4 teaspoons cherry liqueur. Cover with plastic wrap, pressing it directly onto the surface of the pastry cream to prevent a skin from forming. Refrigerate until chilled, at least 2 hours or up to 2 days. Just before using, whisk until smooth.
Fold whipped cream into chilled pastry cream and transfer to cooled tart shell. Working from the outside in, shingle cherries in concentric circles to cover completely.
Heat preserves in a small saucepan over medium heat until warm. Add remaining teaspoon kirsch and stir to combine. Brush mixture over cherries. Refrigerate until ready to serve.
