Line a cookie sheet, with a piece of parchment paper.
Lightly flour the parchment paper (I actually used icing sugar instead of flour), then roll out the puff pastry to loosely form a circle shape. It doesn't have to be perfect, this is a rustic pie remember! Set aside.
Cut up the strawberries, either in halves or thirds.
Place the strawberries in a bowl, and mix them with the sugar and cornstarch.
Pile the strawberries onto the centre of the pastry.
Fold the edges of the pastry over to cover the outer edge of the fruit pile. Overlap as needed.
In a separate bowl, mix together the egg and 1 tbsp of water. Then using this mixture, brush the pastry.
Sprinkle the extra sugar on to the pastry.
Place the pie into the oven, then immediately turn down the heat to 375 degrees.
Bake for 40 minutes...until the pastry is golden brown.
When the pie is done baking, remove it from the oven, and now it is time to add the glaze.
Heat up the apricot jam for about 30 seconds in the microwave, then brush it onto the pie.
