Pear and Chocolate Tart

It is extraordinary that there is no additional sugar added to this tart. I admit that we tend to like less sweet desserts, and if you do, I'd recommend sprinkling a tablespoon of sugar on top after the initial 10 minutes of baking.

Part 1 - the pie crust

1 cup (150g) flour
¼ tsp salt
1 Tbsp sugar
½ cup (4oz/114gr) butter, cut into pieces
1 egg yolk
1 Tbsp + cold water

1. Follow the instructions for the Pie Crust, but substitute the vanilla for 1 egg yolk and be careful about the amount of water you add to avoid having a wet dough. 
2. Put the crust to chill for at least 15 minutes.

Part 2 - the filling

4 oz/114g 70% dark chocolate, chopped fine
3 to 4 pears cut in half, peeled and cored
1 egg
1 egg yolk
½ cup heavy cream
1 tsp vanilla

1. Preheat oven to 400°F.
2. After chilling the crust, sprinkle in the chopped chocolate, and arrange the pear halves, cut-side down, to fill the crust as completely as possible, most easily accomplished if arranged in an attractive flower pattern.
3. In a small bowl whisk together the egg, yolk, cream and vanilla to make a simple custard.
4. Use a spoon to pour the custard mix evenly over the pears so that they have all been wet by the liquid - this will help them brown nicely. 
5. Bake for 10 minutes, then turn down the heat to 350°F and cook an additional 25 to 30 minutes.
6. If the pears have not caramelized, put under the broiler until they do.
