Cheese Storage

Ask the Test Kitchen

After opening a block of low-moisture part-skim mozzarella cheese, I place it in a resealable bag and store it in the refrigerator. Unfortunately, it’s not long before it begins to develop mold. What can I do to keep it from spoiling? —L.S., Bowling Green, OhioOpened cheese should be wrapped with waxed paper, then wrapped again with a tight seal of plastic wrap or foil. Mozzarella cheese stored this way in the refrigerator at a temperature of 34° to 38° will keep for several weeks. If mold develops, trim off the mold plus 1/2 inch extra of cheese and discard it. The rest of the cheese can be eaten. High-moisture cheeses such as cream cheese or cottage cheese should be discarded if they develop mold.
