Peel apples, core them and slice into small chunks.

Melt the butter in a pot over medium and add the cinnamon.

Stir in the apples, sugar & 3 tablespoons water.

Cover and cook, stirring every few minutes for 7-12 minutes or until slightly soft.

In a bowl, combine cornstarch and water.

Whisk in this slurry slowly to the pot and cook another 2 minutes or until thick. (You may not need it all)

Let cool!
