In a bowl of a stand or electric mixer, add the butter and sugar and whip it on high speed for 5-8 minutes until they are properly creamed together.
260 gs unsalted butter, softened, 200 gs caster sugar
Once that's done, add the eggs and whip on medium-high speed until there are no liquid streaks left in the batter and the eggs are properly incorporated in the batter.
2 eggs
Turn the mixer down to a slow speed and gradually start adding the flour. Mix until the flour is just incorporated into the dough. Make sure not to overmix, or your dough will become too sticky. The final dough should just hold it's shape together.
500 gs all-purpose flour
Transfer the dough to a baking paper, then place another sheet of baking paper on top. Roll the dough to 2mm thickness evenly, then let it chill in the freezer for 15 minutes. Freezing the dough allows it to hold it's shape when you shape it around your tart ring or pan.
After chilling, cut and shape the dough as per your tart ring, then chill it for another 15 minutes. If you are not using a perforated tart ring, poke small holes on the base of the pastry with a fork to allow even baking. The holes also stop the pastry from rising while baking.
Pre-heat the oven to 160 degree celcius, then bake the tart for 15-20 minutes, or until golden brown. Bigger tarts might take a longer time
