I don't think it actually is, y'know.
Last night I made a rather delicious concoction of raw apple, celery, yogurt, lemon juice and mint. Today, buoyed by the positive experience, I made the terrible mistake of having some raw celery sticks as a snack. Awful, truly awful. It turns out that apple, yogurt, lemon juice and mint are all delicious but raw celery is not.
