Fresh mozzarella is usually sold floating in whey, and feta cheese is often sold soaking in brine. Once I've opened the container and used part of the cheese, how should I store it in the fridge to make it keep the best for the greatest time? Specifically:
Should I store the cheeses in liquid, or dry in a covered container?
For mozzarella, should I put it away in its original whey, or put it in a clean container with fresh water?
For feta, should I store it in the brine it came in, or change the brine before putting it away?
