in measuring cup, add vinegar and water to make 3/4 c. total. Add slowly and only as much as needed to make dough cling together. (I actually needed more water than this.)
Handle gently. Don't kneat it. Divide in to 6 disks. Chill for 1 hr. before rolling if dough is too soft to handle.
Bake portions you are using for 10 mins. at 450 before adding filling.
