In a large bowl, whisk together flour and salt. Using a pastry blender, cut in cold butter and shortening until mixture is crumbly.
Slowly pour ½ cup ice water and vinegar into flour mixture. Using a fork, mix until a shaggy dough forms.
Turn out dough onto a lightly floured surface, kneading 3 to 4 times until dough comes together, and shape into 2 disks. Wrap each disk tightly in plastic wrap and refrigerate for at least 1 hour or up to 2 days.
