In a food processor, combine flour and salt and pulse for a few seconds. Next add 1 1/2 tablespoons of the butter and the cream cheese and process for 15 seconds. Then, add the remaining 4 1/2 tablespoons butter and process for 6 seconds. Finally, add 1 tablespoon ice water and pulse 4 times. Empty the contents of the processor into a plastic bag and knead, so your warm hands don't touch the dough. Form a flat round. Keep the dough in the bag and chill for 45 minutes before rolling out. Place in a pie dish, add your favorite filling and cook accordingly.
