I love to keep a bowl of celery sticks in the fridge; they make a great healthy snack and pair well with everything from ranch dip to peanut butter and raisins. My sons will always reach for a ready-made snack, even if it is as healthy as celery. But occasionally I don’t get around to slicing it, and it creeps to the bottom of the vegetable drawer, lost under a pile of greens and other produce. By the time we find it, the celery is limp and unappealing.
