Put the flour and salt (if using unsalted butter) in a large bowl and add the cubed butter. Using your fingertips rub the butter into the flour until you have something that resembles breadcrumbs. * As an alternative use a food processor to pulse the butter and flour into crumbs-its much easier!
Add water ( just enough to bind the dough together) and stir in. Using your hands gently knead the dough until you have one solid mass of dough, handle as little as possible
Shape into a ball and wrap in cling film. Pop in the fridge for 30 minutes to chill.
Preheat the Oven To 200c
After 30 minutes, unwrap the dough and place on a floured surface. Roll out into a large circle, big enough to fill an 8 inch Quiche/tart dish
