Shred cheese

My family loves shredded cheese. We use cheddar & mozzarella mostly. I usually buy the bag kind when it is on sale. But sometimes, the bag stuff will start getting moldy before we can use it all. It is nearly impossible to seperate it to be used. I recently found block cheese cheaper than the pre-shredded cheese. So, I broke out the cheese grater and got to work. I shredded into a large bowl, then divided the cheese into smaller portions to freeze. This way I can not waste cheese, and I don't eat the added cellulose- whatever that comes in the pre-shredded kind to keep it from sticking. I find that my frozen doesn't stick together, even without additives!
