Abstract
Abstract A crisp apple wafer-shaped snack is made from apples which are thinly sliced, exposing the seeds. The seeds are removed by washing, the slices are treated to prevent browning and are steeped in a sugar solution. Then the slices are rapidly dried, in thirty minutes or less, to form a crisp delicious snack which may include the apple peel as well as the carpels in which the seeds were contained.
