In a bowl using an electric whisk, or a free standing mixer using the paddle attachment, cream the butter, sugar, vanilla and salt until pale and fluffy.
Once it is pale and fluffy, add the eggs to the bowl and mix until well incorporated.
Add in the flour and almonds and mix until just combined and a dough is starting to form. Form into a flat square dough and cover with cling film. Chill until firm.
Preheat the oven to 180 degrees celsius (Fan). Using a rolling pin, rough the chilled dough on a lightly floured surface to a thickness of 2-3mm.
Carefully lift the dough onto the tart tin, slowly pressing it into the corners of the tin. This can be a little tricky, but if you have floured hands, and it it cool, you will be fine! Trim any excess dough from the tin using a knife and chill again for 30mins or so.
Line the pastry with baking paper or cling film and fill with uncooked rice or baking beans. Place in the oven for 15-20 minutes until starting to go golden brown. Then remove the baking beans and paper and continue to cook until golden brown and has dried out.
