Core and cube the apples and place in a large bowl of cold water to avoid browning.
Whisk together the cornstarch with Sparkling Ice in a small mixing bowl, set aside.
In a medium saucepan melt 2 tablespoons of the butter.
Add the apples, salt, and cinnamon. Sautee over a medium flame for 3 minutes.
Pour the Sparkling Ice and cornstarch mixture into the pot, stirring continuously.
Simmer for 5 minutes.
Turn off the heat and stir in the remaining tablespoon of butter.
