Make the dough: Whisk the wet ingredients together in a small bowl.
56 grams sourdough discard, 1 egg
In a separate large mixing bowl, whisk the dry ingredients together.
150 grams all-purpose flour, 3 grams salt, 60 grams powdered sugar
Rub the cold butter into the dry ingredients.
113 grams unsalted butter
Make a well in the center and pour the sourdough discard mixture in. Using a stiff spatula or wooden spoon, bring the dough together. Lightly knead the dough until it clumps together.
Turn the dough out on a large piece of plastic wrap. Wrap the dough and flatten it into a small disk.
Chill the dough: Refrigerate the dough for at least 30 minutes before rolling it out.
Fill the tart pan: Let the dough warm up at room temperature for 5 minutes, this will make it much easier to roll out.
Unwrap the dough and set it on a heavily floured work surface. To flatten the dough, position a heavily floured rolling pin on the center of the dough and roll upward. Using a bench scraper, give the dough a quarter turn. Repeat until the dough forms a 12-inch circle.
Fold two 12-inch pieces of aluminum foil into a 3-inch wide rectangle. Cross the slings in the center of a tart pan.
Lift the rolled out dough and position it in the center of the pan. Press the dough into the pan but be careful not to stretch the dough or it will shrink as it bakes.
Using a paring knife, trim the excess dough. Refrigerate the pan uncovered.
Prep: Preheat the oven to 375 F.
Blind bake: Line the tart with parchment paper and fill with pie weights. Make sure to press the weights into the edges of the pan.
Bake the crust for 20 minutes. Remove the parchment paper with pie weights and set aside.
Using a fork, dock the bottom of the crust, this will prevent it from puffing up and shrinking.
Continue baking for another 10 to 15 minutes or until golden brown and fully baked.
Transfer to a wire rack and let the tart shell cool fully.
Make the date caramel: Remove the pits from the dates by pulling them apart lengthwise and removing the seeds. Place the pitted dates in a small bowl and soak them in hot water.

113 grams heavy cream
Let the mixture stand for 5 minutes. Whisk the mixture vigorously until smooth and silky.
Assemble the tart: Spread an even layer of date caramel on the bottom of the tart crust. Pour the warm ganache over the date caramel. Spread the chocolate to the edges of the tart.
Chill the tart: Refrigerate the tart for at least 4 hours, ideally overnight.
