Place the flour, salt and diced butter in the bowl with the dough hook. Switch the machine on and add the water via the feed tube.
Continue blending and switch the machine off as soon as the dough forms a ball.
Leave in a cool place for 1 hr.
300 g dough is sufficient for a 30 cm pie dish. If the mixture fails to form a ball, add a little water.
The amount of water required will depend on the absorbent capacity of the flour.
