Combine all ingredients in a large bowl (or food processor bowl) and mix until a ball is formed. If dough is dry, add more water, a tablespoon at a time, until moist. If dough is sticky, add more flour, 1 tablespoon at a time, until dough is smooth.
On a floured work surface, knead dough 3 to 4 minutes, or until elastic. Cover dough with plastic wrap and refrigerate for at least 30 minutes.
