Cream the butter and sugar in a bowl for 2-5 minutes until pale and fluffy. Add the beaten egg and mix until well combined.
65 grams softened butter, 40 grams icing sugar, 1 egg, beaten separately
On low speed, gradually add the flour and salt into the mixture until it forms a thick dough. Do not overmix at this step.
125 grams all-purpose flout, Pinch of salt
Wrap the dough in cling film and let it chill for one to two hours, until it's not soft, then roll it out to 2mm thickness between two sheets of baking paper.
Line your tart pan with the dough, making sure all the edges are covered. Leave an overhang of the dough from the edges as the pastry shrinks while baking. Poke holes into the base of the tart with a fork and let it chill in the fridge for 30 minutes.
Preheat the oven to 180 degrees Celsius and prepare the tart shell for blind baking by places a piece of round baking paper on the bottom of the tart shell and placing baking beans or uncooked rice on top of it.
Bake the tart for 15-20 minutes, then remove the weight and baking paper from the bottom of the tart shell and give it an egg wash. Bake again for 5 to 10 minutes until the tart shell is golden brown. Cut any excess dough from the edges by running a sharp knife against the edge of the tart shell as soon as it comes out of the oven.
