Add flour and salt to a food processor. Pulse 3-4 times.
Add cold butter to the food processor and pulse until crumbly, about 4-5 times.
Add ice cold water in 1 tbsp increments, pulsing in between until the dough comes together. (10 tbsp was the sweet spot for me)
Lightly flour a flat surface and turn dough out into the center. Use hands to gently bring the dough together into a ball. Divide in the dough in half and then gently flatten each into a disc.
Wrap and refrigerate for at least 2 hours, up to 5 days.
