Tart Dough

Contributed by André Jaggi

Combine the flour and salt in a food processor and pulse for a few seconds. Add the shortening and process until completely incorporated. Add the butter and pulse until the mixture resembles small peas. Add the ice water and pulse until the dough is evenly moistened and just begins to hold together.
Transfer the dough to a work surface and gather it into a ball. Divide the dough in half and pat each half into a 6-inch disk. Wrap the disks in plastic and refrigerate for at least 30 minutes or freeze for up to 1 month.
