Fresh Orange Tart - cooking recipe

Ingredients

2 small oranges, thin-skinned, washed
1 1/4 cups water
1/2 cup granulated sugar
1/2 cup all-purpose flour
1/3 cup unsalted butter, diced, chilled
1/2 cup superfine sugar, divided
1 egg
2 egg yolks
2 cups whole milk
4 tablespoons cornstarch
1 teaspoon pure vanilla extract

Preparation

Slice the oranges thinly.
In a saucepan combine the water & granulated sugar & heat, stirring until the sugar has dissolved, then add the orange slices. Reduce the heat & simmer for 30 minutes.
Remove the orange slices to a sheet of parchment paper.
Put the flour in a mixing bowl, then add the butter & rub with your fingertips until it resemples coarse breadcrumbs.
Stir in ONLY 1/4 cup of superfine sugar, combining well.
In another container, whisk the whole egg, then add it to the flour mixture, stirring until the mixture starts to form a dough. Then, with lightly floured hands, bring the mixture together & knead it briefly.
Roll out the dough on a lightly floured surface & use the dough to line a 14\" by 4 1/2\" oblong, loose-bottomed tart pan. Chill this pastry for 20 minutes.
Preheat the oven to 375 degrees F & place a heavy baking pan in the oven to heat.
Line the pastry with parchment paper & fill it with pastry weights (or dry beans), then place it on the preheated baking pan & bake for 20 minutes.
Remove the paper & the weights, then return it to the oven for another 5 minutes, or until the base is baked & crisp. Leave it in the pan & put it on a wire rack to cool.
In a saucepan, heat the milk until ALMOST boiling.
In a mixing bowl beat the 2 egg yolks, the remaining 1/4 cup of superfine sugar, cornstarch & vanilla extract, along with 2 or 3 tablespoons of the hot milk, until smooth.
In a steady stream, pour in the rest of the milk, stirring all the time.
Return the mixture to saucepan & cook, stirring, until thickened, then remove from the heat & cool thoroughly, stirring occasionally to stop a skin from forming over the top.
When the mixture is cold, spoon the custard into the pastry shell & make sure the surface is level before arranging the orange slices on the top.
