Add the flour, butter, and salt to a food processor. PULSE only until the mixture resembles coarse crumbles. Do not overmix.
Mix the ice water and vinegar in a small bowl.
Add 1/2 of the water-vinegar solution to the processor and PULSE for approximately 10 pulses.
Add the remaining water-vinegar solution and PULSE until mixture JUST comes together to form a soft dough. Do not overmix.
Turn the dough out onto a piece of parchment paper. Use hands to form a round shape so that you can evenly divide in half.
Wrap each half in plastic wrap and chill for 30 minutes or use right away. These crusts also freeze very well!
When you're ready to use, roll out on a piece of large parchment paper and insert the crust into a pie dish to use in your favorite recipes.
