01 - In a mixing bowl, combine flour, salt, and confectioners’ sugar. Incorporate the cold butter using fingertips until the mixture resembles fine crumbs. Add the egg and mix until a homogeneous dough is formed. Shape into a ball, wrap in plastic film, and chill for 30 minutes.
02 - Preheat oven to 350°F. Roll out the chilled dough and line a 10-inch tart pan. Prick the base with a fork, cover with parchment paper, and fill with pie weights. Bake for 20 minutes, remove the weights and paper, then bake for an additional 10 minutes until lightly golden. Allow to cool completely.
03 - Heat the milk with the vanilla until just simmering. In a separate bowl, whisk egg yolks with sugar until pale, add cornstarch and mix well. Gradually pour in a small amount of hot milk, whisk, then return everything to the saucepan. Cook over medium heat, stirring constantly, until thickened. Off the heat, blend in the butter. Cover with plastic wrap touching the surface and chill until cool.
04 - Wash, hull, and slice the fresh strawberries as desired.
05 - Spread the chilled pastry cream evenly in the cooled tart shell. Arrange the strawberries attractively on top.
06 - Gently heat the apricot jam with water, blend until smooth, and, using a pastry brush, lightly glaze the surface of the strawberries for a glossy finish.
07 - Refrigerate the tart for 1 hour before serving to ensure proper set and flavor development.
