There are 4 key elements to keeping celery crisp longer, in the fridge. First cut a little off the top of all the celery stalks, and then cut the root end off, exposing all celery stalks on that end also. Run the whole bunch under cold water, especially on both ends. Now wrap all the stalks in a wet paper napkin. Then wrap the celery & paper towel in aluminum foil, enclosing all. Put this foil package in your vegetable crisper, and the celery will stay crisper much longer than if you just put it, as you bought it at the grocery.
This does work! Not sure if aluminum foil is a necessary part of this process, but maybe putting the celery wrapped in a wet paper towel in a sealable plastic bag might work just as well. I think it is important to keep the celery moist as the cut ends probably suck up moisture to keep the celery crisp.










NOTE: I just thought to google regarding how to store carrots longer. I found an Internet article that basically said you can make them last longer, just as you do celery above, wrap in a wet paper towel. I might also try this, and cut both ends of the carrot off, but I don’t see them “sucking in the water” like celery seems to do.
