Sift the flour into a large bowl.

Add the cubed chilled butter and rub it in with your fingertips until the mixture resembles fine breadcrumbs.

Then stir in the salt & sugar.

Finally add 2-3 tbsp of cold water a tbsp at a time and mix together until you have a firm dough.

Turn the dough out onto a floured surface and knead lightly.

Wrap in cling film and chill for 30mins before use.
