Preheat the oven to 350 degrees F. In a medium bowl, stir together all of the crust ingredients and press evenly and up the sides of 9-inch-round fluted tart pan. Bake for 10 minutes, or until firm. Cool on a rack for 15 minutes before filling.
PREPARE THE FILLING:
Place the chopped chocolate in a large bowl. In a small saucepan, bring the cream just to a boil, then pour over the chocolate in the bowl and let stand for 5 minutes. Stir together until smooth. In a separate bowl, whisk together the eggs, vanilla and salt. Whisk the egg mixture into the melted chocolate. Pour the filling into the cooled crust. Bake about 20 minutes, or until the filling is set. Cool completely on a rack, about 1 hour.
PREPARE THE GLAZE:
In a medium saucepan, bring the cream to a boil. Remove from heat and stir in the chocolate until smooth. Stir in the corn syrup, then warm water. Pour the glaze onto the tart, then tilt and rotate the tart so the glaze coats the top evenly. Let stand until the glaze is set, about 1 hour.
Serve individual slices with whipped cream or ice cream.
Notes
*If you’re unable to find the chocolate type of graham crackers, use regular and add about 2 tablespoons cocoa powder
*This tart is best when eaten the day its made, but can be made (without glaze) 1 day ahead and chilled. Bring to room temperature before glazing.
*Pipe whipped cream on top and add desired garnishes… berries for summer, candy corn for fall, or just a few chocolate jimmies.
If you are making this recipe GLUTEN-FREE, just be sure to use a brand of chocolate that is known to be GF, and also use GF graham crackers.
