Directions

1. 1

3. 3
   With the processor running, pour in the vinegar, then 1/4 cup ice water; process just until the dough comes together.
4. 4
   (If the dough is still crumbly, add up to 1/4 more ice water, 1 tablespoon at a time.)
5. 5
   Pat the dough into a disk, and wrap in plastic.
6. 6
   Refrigerate the dough until cold, at least 1 hour and up to 1 day.
7. 7
   The dough can also be frozen up to 1 month; thaw completely in the refrigerator.
