. . . you will need . . .  apples, naturally . . . and I like freshly picked apples from a local apple orchard . . .  they taste so much better than store bought . . . but if you are in a pinch, get some really good, really big apples at your local grocer. Just remember that apples from the grocer are sometimes coated in a waxy film . . . you will need to wash your apples or the melted caramel just slides right off. That is why I recommend freshly picked apples from an orchard.
