Step 3
Add 1/2 cup of ice water through the feed tube, pulsing occasionally to mix, to distribute the liquid and moisten the dough. You're looking for the dough to form into moist crumbles that build upon the sides of the food processor (see the photo in a blog post), and combine into a smooth clump when gently squeezed with your hand. If the dough is too dry, add tablespoon of ice water, and pulse, until the dough is sufficiently moistened. Repeat as needed, but you shouldn't need to add more than a few tablespoons of extra water at most.
