Apples, cored & sliced
2 tbsp. lemon juice
4 c. water

Mix lemon juice in water, soak apple slices in lemon water mixture about 5 minutes. This is to prevent apples from turning brown. Place on baking racks in oven at 125 degrees for 6 to 9 hours with door slightly ajar. Apple slices will be slightly pliable but not crisp when done. Store in airtight container in cool, dry place.
