Prepare homemade pie crust or use storebought crust
Strain juice from canned tart cherries and place cherries with the apples in the mixing bowl.
Add lemon juice to cherry juice then add water to make 3/4 cup. Add to a small sauce pan.
Into the juice mixture stir in cinnamon, 1/2 of the sugar, cornstarch and salt until well blended.
Heat the mixture for 5 minutes and starting to boil. Remove from heat, then add the rest of the sugar until well blended.
If you don't have a spritzer bottle, you can add the water one tablespoon at a time.
Feel free to use a store bought pie crust if you dont want to make your own!
