yields 8 – 10 servings

ingredients

sweet tart dough
1/2 cup + 1 tablespoon unsalted butter, room temperature
1/2 cup sugar
1/8 tsp salt
1 large egg, room temperature

egg wash
1 large egg
pinch salt

filling
3/4 cup sugar
4 large eggs
3/4 cup heavy cream
1/2 cup lime juice
1/4 cup lemon juice
zest of 3 limes

topping
1 pint blackberries
1 pint blackberries 
2 tablespoons black or red currant jelly

DIRECTIONS

crust
Using a stand mixer with the paddle attachment, combine butter, sugar and salt, mixing on medium speed until smooth.  Add egg and mix until smooth.  Stop mixer and scrape sides of bowl with a rubber spatula.  Add flour, all at once, and mix on low just until incorporated.  Shape dough into two equal balls, and shape each ball into 1/2” thick disks.  Wrap well in plastic wrap and chill two hours or overnight.*

To line a 9” tart pan, place chilled dough disk on a lightly floured surface (i.e. a silicone mat) and roll to 1/8” thick, rolling from center toward edges, in all directions.  Lift and rotate dough a quarter turn after every few strokes, dusting underneath with flour, as necessary, to discourage sticking.  Work quickly to prevent dough from becoming warm.  If dough has warmed, transfer to the refrigerator to firm up for a few minutes.  Otherwise, gently transfer dough to the tart pan, easing it into the bottom and sides and pressing carefully into place.  Do not stretch dough or side will shrink during baking.  Patch tears with extra dough, pressing firmly to adhere.  Trim dough to level with top of the pan using a sharp knife.  Place tart shell in freezer for about 15 minutes or until firm.  Freeze any scraps and the extra disk for future use.  Frozen dough keeps for up to three weeks.

Preheat oven to 325 degrees F.

Once the shell is firm, use a fork or the tip of a knife to dock (make small holes in) the bottom of the tart shell, 2” apart.  Bake for 10-12 minutes or until lightly colored, dry and opaque.  Check during baking and rotate pans as needed, for even color.  Beat egg with salt in a small bowl and lightly brush the bottom and sides of the shell with egg glaze, about two minutes before desired color is reached.  Return shells to oven and bake until lightly colored and egg glaze has set.

filling
Preheat oven to 350 degrees F.

Whisk together sugar and eggs in a bowl.  When well mixed, slowly stir in cream, juices and zest.  Place the cooked tart shell on a rimmed baking sheet.  To reduce spillage, position the pan on the oven rack before pouring filling into the shell.  Bake 35-40 minutes or until the filling is set but still semi-wobbly in the center.  After cooling for one hour, the filling will set to a perfect consistency, soft and smooth.  Make sure to cool before cutting to avoid a gooey mess. 

topping
Once tart has cooled, remove sides from tart pan, using a small, sharp knife to loosen, if needed.  Place crust on a plate.  Carefully rinse blueberries and blackberries and gently pat dry with paper towels.  Arrange blackberries in two concentric circles, about 1” from inside edge of crust.   Mound blueberries in center of tart.  If there are extra blueberries, add another circle (see photo, above) around blackberries. 

In a small saucepan, warm jelly until melted.  Whisk, adding water if too thick.  Use a pastry brush to brush jelly over berries, careful to avoid dripping jelly on the filling.

Tart can be served at room temperature or chilled, according to preference.  Serve unaccompanied or with a dollop of freshly whipped cream.
