Because I cannot find on a regular basis celery, I am trying to preserve what I buy as long as possible.
After trying some methods, the one I found is aluminum foil. I wash the celery, dry it, put in paper towels, then in aluminum foil, then put in the vegetables area of the freezer. I managed to have fresh celery for 2 weeks, maximum, keeping in mind I didn't use a metal knife for cutting the edges.
Is it safe to store celery in aluminum foil?
