Mix plain flour and salt well in a large mixing bowl. Add cold butter cubes and start mixing gently with your fingertips until the mixture resembles fine breadcrumbs.
Now slowly add 1/2 cup chilled water and form into a soft smooth dough. Do not knead the dough too much, stop when everything comes together as one single mass. (the dough can also be prepared in a chopper as shown in the picture using the pulse button).
Wrap the dough in a cling wrap sheet and chill in the refrigerator for at least 30 minutes.
Remove from the refrigerator and leave to rest at room temperature for a few minutes.
Place a large cling wrap sheet on the table and place the dough on it. Roll out the dough into a thin disc, a little bigger than the size of the quiche pan. Place the rolled-out disc on the quiche pan by lifting the cling wrap. (It becomes easier to handle the dough sheet with cling wrap or else it can break while lifting ). Cover the sides of the quiche pan with the dough evenly, remove any excess of it and prick the base with the fork so that the dough does not rise while baking.
Place the prepared quiche pan in the refrigerator for 10 minutes.
Preheat the oven to 200 deg C. Cover the chilled quiche tin and the dough with foil paper and bake for 10 minutes. Remove the foil and again bake for another 10 minutes or till the crust is lightly golden.
