For all my childhood picky-eating preferences, one flavor I've always loved is grapefruit. My mom used to serve them halved, broiled, with cinnamon-sugar sprinkled on top; my mouth waters thinking of it.
But when it comes to juicing, grapefruit's super dominant flavor can't be paired with just any veggie and fruit. And it seems to me that the sour should be countered by a sweet.
I made a winning combo today, and 24 oz. was never so easily swallowed.
1 grapefruit peeled
1/2 head romaine lettuce
2 celery stalks
