Put one gingerbread in each tin.

All steps as a list
  1. Put one gingerbread in each tin.
  2. Add the apple slice to one tin.
  3. Close both and compare after two days: press and taste.

What you see

The gingerbread with the apple is soft, the other has stayed hard. The apple slice has gone wrinkly.

Why it happens

The apple gives off water into the air in the tin. The honey and sugar in the draw in this moisture and hold on to it.
