@frescano i use a bit of star anise when i make baked apple slices along with a pinch of Cinnamon, Sugar, Cardamom and Nutmeg.
you can use water spices you like but the anise adds alot of flavor.
dust one side with the mix and bake for about 10 mins at 350.
they will be a bit crispy but that's the way i like em.
