Rub shortening into flour until it becomes irregular pea sized crumbs.
Dissolve salt and sugar in cold water, then add all at once to the pie crumb mixture and mix just enough to incorporate. Do not overmix!
Transfer dough to a table floured with bread flour and shape into a thick roll. Cover with plastic wrap and allow to rest for 15 minutes in the fridge before rolling.
Recipe Notes
Overworking your dough will produce a mealy dough and underworking will result in a dry and tough dough.
