Preheat an oven to 175 degrees Celsius (350 degrees Fahrenheit).
Roll out the dough on a floured surface to a size slightly larger than your tart tin.
Place the rolled dough into the tart tin and trim the edges with a sharp knife. Use any leftover dough to fill in any holes or tears.
Prick the entire bottom of the pastry case with a fork, but not all the way through.
Then, allow the pastry case to cool in the fridge for an additional 30 minutes or in the freezer for 15 minutes, to prevent shrinking.
Once chilled, place scrunched-up parchment paper in the centre of the pastry and fill it with baking beans or dry rice.
Blind bake the pastry for 15 minutes. Remove the paper and baking beans, and bake for an additional 5 minutes, or until the pastry is golden and crisp. If the middle of the pastry puffs up, carefully prick the bottom with a fork to release the steam.
Let the pastry cool completely before filling it with the pastry cream.
Spread the pastry cream evenly over the cooled pastry base.
Wash and thoroughly dry the strawberries and cut into even slices.
Arrange the sliced strawberries on top of the pastry cream in your desired pattern.
Prepare the glaze by mixing the jam and water in a small saucepan over medium heat until thickened, this should only take a few minutes. Let it cool.
Brush the glaze over the strawberries to seal them and add a shiny finish.
Slice and serve your delicious strawberry tart!
