Toss the apples in a large bowl with lemon juice to keep them from browning and set aside.

Pour cornstarch into a large saucepan and slowly whisk in water to prevent the cornstarch from getting lumpy.

Mix in the sugars, cinnamon, nutmeg, and a pinch of salt and bring mixture to a boil over medium-high heat.

Allow to come to a hard boil, stirring constantly for 2 minutes.

Add the apples and bring back to a boil then reduce the heat to medium low and simmer for 15 minutes or until apples soften to the desired texture.

Cool completely before storing or using.
