Core the apple without cutting it in half. To do this, puncture the top of the apple near the stem and cut around the stem area in a circle. Do this all the way through the apple to make a hollowed circle in the center of it.
Sit the apple on a folded sheet of newspaper.
Place the sheet of newspaper with the apple on it, outside to dry for three weeks. During this time, the apple will shrivel a little bit. This is normal.
Stuff the apple pomander with a sachet of your favorite herbs and flowers. Alternatively you can use cotton balls soaked in fragrant oils.
