Apple Filling for Sweet Empanada Dough

Filling:

 

2 tablespoons butter

4-5 firm green apples (like Granny Smith)

1/2 cup sugar

1-2 teaspoons cinnamon

1/4 cup brown sugar

2 tablespoons corn starch

Pinch of salt (to taste)

1 egg yolk

Sugar for sprinkling

 

 

Make the filling:

 

Peel and core the apples, then cut them into small cubes. Add apples to a saucepan with the butter, sugar, brown sugar, salt, and cinnamon.

Stir apples over medium heat, cooking them until they are just tender. In a small bowl, mix a tablespoon or two of water into the corn starch until smooth. Add cornstarch mixture to the apples and cook, stirring, until mixture starts to thicken.
Remove apples from heat chill apple mixture for at least an hour, stirring occasionally.
