Add the flour and salt to to a bowl or food processor. Cut the butter into 1 tablespoon chunks, and add it to the flour and salt. Pulse the food processor or use a pastry cutter
to work the butter into the flour until the butter is in pieces the size of peas. Add just enough water to form a cohesive ball of dough, with no dry flour left on the bottom of the bowl (about 1/4 cup).
