In a large bowl sift the flour and salt.
Add the cold butter.
Incorporate the butter to the flour, using a pastry blender or a fork or a pastry processor, until crumbs are formed.
Add the water and stir until the water is incorporated. Don’t overwork the dough as butter chunks need to remain visible.
Wrap it with plastic wrap, and refrigerate for 20 minutes.
Transfer the dough onto a lightly floured work surface.
Roll the dough until 3 times the length, to a rectangle of about 6 X 17 inches (15 cm X 45 cm).
Fold the top third down to the center, then the bottom third up and over that.
If necessary brush the excess flour.
Turn it to the left or right and roll out again to three times the length.
Repeat the rolling and folding for a total of 4 to 6 times.
If the dough gets sticky during the process refrigerate for 30 minutes and continue.
Cover with plastic wrap and chill for at least 30 minutes before rolling to use. You can also chill the dough overnight. It keeps well for a couple of days refrigerated.
