-add cinnamon and brown sugar for taste also.
peal and core your apples and then cut the apples into whole round thin slices.( recomended at 1/8th of a inch or 1 quarter inch )
Once cut you must place them in a container filled with a liquid that is 1:3 ratio between lemon juce to water. soak for no more then 10 minutes. Next cover a cookie sheet with parchment paper (not wax paper ). before you put them in the oven you could add the flavoring of your choice. for the cinimon and brow sugar glaze, use 1 teaspoon of cinnamon to 3 teaspoons of sugar.
Idealy you would have a dehydrator and put it on for 6 to 12 hours. In our case we had a gas oven, the differance between a gas oven and electric is that the gas has a lock on the burner so even when we stuck a spoon in the oven door in order to allow the moisture to escape, the oven ended up turning itself off. When I came down to see if they were cooked at 3 am I noticed they were still raw so I Googled the reason and found out there was a setting on the oven called convection that would produce the same effect as having the door open.
So it ended up that our apples dehydrated just great using 180 degrees F, for 5 hour's using a gas oven on convection bake with the door closed and the tray on the middle rack. smelled good too when I woke up, yum yum.
