Gather the ingredients.

Measure flour into the processor with the regular blade attached. Add chilled and cubed shortening and unsalted butter. Add salt, close the lid, and pulse three times with three counts per pulse to lightly mix the ingredients.

With the motor running, pour ice water into the food processor bowl just until the dough starts to get noticeably crumbly. Don't wait until it is a big clump.

Transfer the crumbly dough into a bowl, and form it into a ball with your hand, squeezing it a bit to make it stick together. If it doesn't form a ball, add a tiny bit more water.
