Preheat the oven to 400°F.
Pour the cherries and 3/4 cup of the cherry juice into a mixing bowl. Add the sugar, cornstarch, and salt. Stir well and let sit for 15-20 minutes.
Meanwhile, place a crust in the bottom of the pie pan. Add pie crust weights to the bottom of the crust to prevent bubbling during baking.
Add parchment paper to a baking sheet, then set the pie crust on it to parbake.
Parbake the crust in the preheated oven for 10-15 minutes, or until lightly browned. See the note below for an alternative to parbaking.
If using cutout shapes to decorate the pie, cut those while the crust parbakes.
Stir and then pour all the cherries and juice into the crust. Add the crust cutouts to cover the top of the pie, or if using a single crust, place it over the top, cut 5 or 6 slits for venting steam, and flute the edges to seal the two crusts.
Cover the edge of the pie crust with an aluminum foil ring.
Bake for 40-45 minutes or until the crust is golden brown.
Check the pie during the last 10 minutes of cooking. If the crust is brown under the aluminum foil ring, leave the ring in place. If the crust has not browned under the aluminum foil, remove it.
