My kids and I love watermelon but when I would purchase a whole one and cut it up to store in the fridge it would go bad before we could eat even half of it. A friend told me to only cut what we are going to eat that day and leave the rest of the melon intact in the refrigerator. It really works. I have about a quarter of a watermelon in my fridge that is about a week old and is as fresh as if it had just been cut into.
These two stackable containers come in handy for many things. I pulled out four plastic lids and they fit perfectly. They are deep enough to keep the watermelon out of the juice which keeps it crisp and fresh. If needed, I can punch holes in them for more drainage.
