For crust, in large bowl, combine flour and salt. Using a pastry blender or fork, cut butter into flour until mixture resembles cornmeal. Add 8 tablespoons cold water and stir until mixture holds together in large clumps. Add additional water, tablespoon by tablespoon, if the dough is still dry. Make about 1/4 of dough into a small disc and form remaining dough into a large disc. Wrap discs with plastic wrap and chill at least 1 hour or up to overnight.
