Preheat your oven to an inviting 375°F and prepare the pie crust by rolling it out on a lightly floured surface. Gently place it into a 9-inch pie dish and set aside.
In a medium bowl, delicately combine the cherries, sugar, cornstarch, salt, and lemon juice. Pour this tantalizing filling into the prepared pie dish.
Add a few butter pieces on top of the cherry mixture and then put the remaining pie crust over it. Seamlessly crimp or seal the edges to form a tight barrier around your cherry pie.
To give your cherry pie a golden, glossy finish when baking, paint on top with an egg and milk or cream mixture.
If desired, dust the top of your pie with a bit of flour to make the crust even sturdier.
Bake in preheated oven for 40-45 minutes or until it reaches a golden brown color on top. Allow cooling before slicing and serving up this tasty treat!
