In a bowl, first, cream the butter on medium-high speed until smooth for 1 minute.
Add sugar and cream it together on high speed for 2 minutes or until creamy and smooth. Stop as soon as smooth, no need to beat a lot of air into the mixture.
Add half of the egg mixture and beat until incorporated.
Use a rubber spatula to scrap down the sides of the bowl.
Add flour and an almond meal. Slowly mix until flour is evenly moistened. Make sure to stop mixing as soon as the dough comes together to avoid overworking the pastry.
Cover the dough with plastic wrap and let chill in the fridge for about 10 minutes as it helps to handle the dough easily.
Transfer the pastry dough onto a large sheet of baking paper or plastic wrap. Work very lightly to form a smooth ball.
Place a second sheet of baking paper over it then roll the dough gently into a small circle. Place the rolled pastry over a flat tray and put it in the fridge to chill for at least 1 hour upto overnight.
Once the dough has chilled, take it out from the fridge. Let it sit on the counter for a few minutes to soften slightly for easy rolling.
Using a rolling pin, roll out the dough about 2 cm bigger than the size of your baking pan. Place the tart pan you will use over the rolled pastry to check that it is rolled large enough.
The pastry is soft and easy to roll but try not to roll it too thin or it will be hard to line the pan and the pastry will tend to crack once baked.
Peel off the top sheet of plastic wrap, then carefully lift the dough into your tart pan and place it back on. That is the easiest way to transfer the dough from the counter to the pan.
Gently but firmly and evenly press the dough onto the bottom and sides of the pan. Remove the second sheet of plastic wrap.
Make sure the pastry is pressed tightly against all the edges to avoid shrinking in the oven.
Trim off the excess dough either by running your rolling pin over the edges, or cutting it off with a sharp knife. If there are any cracks, patch them up with your fingers.
Place back in the fridge for at least 1 hour, or up to 24 hours. Cover it with plastic wrap so that the pastry doesn’t dry out.
