Availability: Sometimes in summer
Storage tips: Refrigerate in a plastic bag. Celery should store for at least 2 weeks. Separate leaves from stalks for best storage and use leaves quickly.
How to eat: Celery is excellent raw in salads (veggie salads or meat/egg salads). It's also great in soup and raw with dip.
How to preserve: Freeze it! I freeze it simply chopped up as I would use it in a soup and that way it's easy to use straight out of the freezer. The texture is lost so it doesn't lend itself to raw uses after it's been frozen.
