Reviving greens to (almost) their just harvested freshness is super easy. You can revive any greens, kale, lettuce, chard even broccoli will work using this method.
This droopy bunch of kale is about a week old. It was in a plastic bag in the refrigerator. It is still fine to eat. If I was cooking the kale I would just wash it and go ahead and cook it. In this case I wanted a kale salad so I am going to revive it to give it a little crunch and freshness back.
Don’t give up on your produce too soon! Give it a dunk and a chance!
