Place dry ingredients in a food processor and pulse 2-3 times to incorporate. Add the cold butter and pulse again 6-7 times until the butter is the size of peas-it’s OK if there are a couple of larger pieces. Add the water all at once and pulse again until the dough looks like gravel. Stop and pinch the dough with your fingers and if it comes together it’s done but if it’s too powdery add more water and pulse 1-2 more times. Once the dough comes together in your hands, it’s done. Turn the dough out on a clean work surface and bring it together. Flatten the dough (as best you can,doesn’t have to be perfect) into a rectangle shape, wrap in plastic and place in the fridge for 30 minutes to rest. *** Can also be made by hand using pastry cutter or stand mixer, using paddle a attachment.
