Wash your apples and peel, cut and dice them into 1in pieces
Add your diced apples, sugar, lemon juice, cinnamon, nutmeg and vanilla into a medium sized saucepan. With a wooden spoon stir the mixture until the apples are evenly coated.
Cook the apples on medium heat for 10-15 minutes stirring every so often until they are tender and soft. Turn the heat to a low simmer.
In a small bowl add the cornstarch and water and mix until you see no more dry clumps. Add this to the cooked apple mixture and allow it simmer on low for 2 mins. You should notice the mixture start to thicken.
Turn off the stove and let the apples cool down. Once the apples have cooled you can place them into a container and refrigerate.
