Defrosting frozen cheese is a simple process that can be done in a few different ways. The most important thing to remember is to thaw the cheese slowly and evenly to prevent it from becoming rubbery or crumbly.
One way to defrost frozen cheese is to place it in the refrigerator overnight. This is the slowest method, but it is also the gentlest and will result in the best quality cheese. If you need to defrost cheese more quickly, you can place it in a bowl of cold water for 30-60 minutes. Be sure to change the water every 15 minutes or so to keep it cold.
