Slice apples thin - between ⅛ inch and ¼ inch.

In a large bowl combine water, lime juice, cinnamon, and sugar. Place apple slices in mixture and soak 2-3 minutes.

Transfer apples slices to dehydrator trays, or a baking sheet linen with a silicone liner.

If using a dehydrator set to medium heat and dry until crisp - usually 4-6 hours. Check at 4 hours.

If using an oven, turn to lowest temp - around 200 degrees. Prop oven door open with a wooden spoon to allow better air flow and bake for 3-6 hours. Check at 3 hours.

Store in an airtight container.
