I love cheese. We love cheese in this house. I usually have around 4-5 blocks of cheese at any given time that we enjoy for snacks. Thought I'd share how I keep them fresh. I cut the unopened package off center at about 2/3 the way.
Then, along with a few crackers and an apple I enjoy a sliver or two :)
When I have finished my tasty snack, all I have to do is slide the other half back over the cheese. As the remaining cheese block get smaller I fold it in on itself and slide them together.
It used to drive me crazy to find my cheese dried out because no one wanted to take the time to put it in a container, or a ziploc bag. This works like a charm :)
