Cheese: Stick it in the freezer
I often buy grated cheese in five-pound packets. The easiest way to handle this amount is to put it into the freezer as is. I just thump the bag on the counter a few times before opening it. Usually enough cheese will release from the frozen clump for my meal. Occasionally, it is inconvenient to have all my cheese frozen, like when I want to serve some along with a baked potato or as a topping with a taco meal. You might also consider repackaging a five-pound package of cheese into zip-top plastic bags.
