Cheese that has been frozen may not melt as quickly or as smoothly as cheese that has not been frozen. When Land O’Lakes Customer Concerns receives a report that cheese is not melting properly, one of the first factors we check on is whether or not the cheese might have been frozen at some time.
If you do choose to freeze cheese, divide the cheese into small packages so it will freeze quickly and wrap the cheese tightly to prevent drying of the surface. Frozen cheese should be thawed slowly in the refrigerator and used as soon as possible after thawing. Flavor of cheese frozen for short periods (less than 3 months) should not be affected, but texture changes (crumbly, grainy) will limit the use of the cheese to cooking. Please note that even if cheese is frozen, it should still be used within the expiration date that is indicated on outside of case or packaging.
The white crystalline matter on the surface of cheese (similar to grains of salt) is not mold. It is calcium salts that have precipitated out of the cheese. This substance is not harmful, and can be trimmed off the cheese before use.
