If you're using a vertical slow juicer, cut the apples into quarters or eights, cut the celery into small quarter to half inch pieces so that it doesn't clog the pulp ejector and cut the carrot into quarters so that it fits into the feed chute.

If you're using a centrifugal juicer pack the spinach in-between two apples before starting the juicer up.

Best served with ice. Enjoy.
