Stir together the flour, sugar, and salt. Using a pastry cutter or a food processor (if I had one I would use it!), cut the shortening and butter into the flour until the mixture resembles coarse crumbs. It is only about 10 pulses with a food processor but a bit more work by hand. One trick to make the process a little easier is to freeze your butter beforehand, then grate it into the flour mixture before cutting it in with the pastry cutter if not using a food processor.

Sprinkle 2 tablespoons of the ice water over the mixture. Using a fork, gently stir the water in to the flour mixture, then repeat with the remaining water, adding only 2 tablespoons at a time, just until the dough starts to come together.

Divide the dough into two even pieces (if making a double-crust recipe). Turn each piece of dough onto a sheet of plastic wrap and flatten each into a disc and wrap tightly in plastic wrap. Refrigerate for 1 hour, then allow the chilled dough to sit on the counter to soften slightly for 10 minutes before rolling out.
