Step 1 Cut the butter into half-inch cubes and dust with about one-fourth cup of the flour. Chill until the butter is very cold and firm.
Step 2 Place the remaining flour, sugar and salt in a food processor and pulse to combine. Add the chilled butter mixture and, using quick pulses, process until the butter pieces are the size of peas.
Step 3Add the ice water 1 tablespoon at a time and continue to pulse until the mixture barely comes together and you can still see large streaks of butter.
Step 4Gently press the mixture together to form a circle about one-half-inch thick. Wrap well with plastic wrap and chill for at least 1 hour.
