1. In large skillet or pot, combine apple juice and cinnamon stick; bring to a low boil while preparing apples.
2. With sharp knife, slice off 1/2-inch from top and bottom of apples and discard (or eat!). Stand apples on either cut end and saw gently crosswise into very thin (1/8-inch) rings, rotating the apple as necessary to get even slices.
3. Drop apple slices into boiling juice; cook 4 to 5 minutes or until slices appear translucent and lightly golden. Meanwhile, heat oven to 250 degrees F.
4. With slotted spatula, remove apple slices from juice and pat dry. Arrange slices on cake-cooling racks, being sure none overlap. Place racks on middle shelf in oven; bake 30 to 40 minutes until apple slices are lightly browned and almost dry to touch. Let chips cool on racks completely before storing in airtight container.
