Small apples
String, cut in lengths
Apple corer

Wash apples then remove the core from three or four of them using the apple corer. Thread a string through each apple and tie a knot. With the other end of each string, hand the apples outside in the sun to dry. (Or apples can be hung from a rack in the oven. Set the oven very low, 150 degrees.) When they are dried, remove the strings, slice and eat.
