to make the pie crust: combine dry ingredients in the bowl of a food processor, pulse to combine
cut the butter in chunks and add to the food processor, pulse to chop until it looks like bread crumbs
combine water and vinegar, pour half of it in the food processor, pulse, add half of the remaining, pulse 4-5 times, if it's not coming together as a ball add remaining water and pulse until it comes together, don't run it past this point or you'll overwork the dough
wrap in plastic wrap and refrigerate until 30 minutes before you want to roll the dough
