Crust for Tarts

from Helene

4 Tbsp. ice water, plus more as needed
¾ tsp. apple cider vinegar
1 ½ cups unbleached all-purpose flour
1 Tbsp. sugar
¾ tsp. salt
9 Tbsp. (4 ½ oz.) cold unsalted butter, cut into cubes

In a small bowl or measuring cup, combine 4 Tbsp. ice water and the cider vinegar.

In the bowl of a food processor, combine the flour, sugar, and salt. Pulse to blend. Add the butter, and pulse until the mixture resembles a coarse meal; there should be no pieces of butter bigger than a large pea. With the motor running, slowly add the water-vinegar mixture, processing just until moist clumps form. If you pick up a handful of the dough and squeeze it in your fist, it should hold together. If the dough seems a bit dry, add more ice water by the teaspoon, pulsing to incorporate. I sometimes find that 1 additional teaspoon is perfect.

Turn the dough out onto a wooden board or clean countertop, and gather it, massaging and pressing, until it just holds together. Shape it into a ball, and press it into a disk about 1 ½ inches thick. If the disk cracks a bit at the edges, don’t worry; just pinch the cracks together as well as you can. Wrap the dough in plastic wrap, and then press it a bit more, massaging away any cracks around the edges, allowing the constraint of the plastic wrap to help you form it into a smooth disk. Refrigerate the wrapped dough for at least 2 hours. (Dough can be kept in the refrigerator for up to 4 days or frozen for up to 1 month. Thaw it in refrigerator overnight before using.) Before rolling it out, allow the dough to soften slightly at room temperature.
