Hong Kong Style Egg Tarts

1 . Stage

In a medium bowl, mix together the confectioners' sugar and flour. Mix in butter with a fork until it is in small crumbs. Stir in the egg and vanilla until the mixture forms a dough. The texture should be slightly moist. Add more butter if it is too dry, or more flour, if the dough seems greasy. Shape dough into 1 1/2 inch balls, and press the balls into tart molds so that it covers the bottom, and goes up higher than the sides. Use 2 fingers to shape the edge into an A shape.

2 . Stage

Preheat the oven to 450 degrees F (230 degrees C). Combine the white sugar and water in a medium saucepan, and bring to a boil. Cook until the sugar is dissolved, remove from heat and cool to room temperature. Strain the eggs through a sieve, and whisk into the sugar mixture. Stir in the evaporated milk and vanilla. Strain the filling through a sieve, and fill the tart shells.

3 . Stage

Bake for 15 to 20 minutes in the preheated oven, until golden brown, and the filling is puffed up a little bit.
