Cheese is a staple in many refrigerators, but what happens when you discover that fuzzy, unwelcome growth? Mold and cheese have a complex relationship, beginning even before cheese hits the store shelves. While mold plays a crucial role in the flavor development of certain cheeses, it’s not always a welcome sight. Let’s unravel the mystery of mold and cheese, separating the safe from the unsafe.
Why Does Some Cheese Have Visible Mold?
Some cheese varieties, like gorgonzola with its iconic blue veins or brie with its white rind, are intentionally made with mold. This mold isn’t just for aesthetics; it contributes to the cheese’s unique flavor and character. Enjoying these cheeses, mold and all, is completely safe.
Identifying Unwanted Mold
The key distinction is that naturally moldy cheeses have uniform mold growth, while new, unwanted mold tends to appear on the edges and can be different in color and texture. This unwanted mold is often fuzzy and sporing, a clear sign that it’s time to exercise caution.
What to Do When Mold Appears
If you spot mold on cheese that shouldn’t have it, like mozzarella, cheddar, or Swiss, it’s best to discard it. While it’s unlikely to make you sick, it won’t taste pleasant. For hard cheeses, such as Parmesan or cheddar, cutting away the moldy portion and a surrounding inch is usually safe. However, avoid cutting directly into the mold to prevent spreading. Soft cheeses, like ricotta or cottage cheese, are more delicate. Any sign of mold on these cheeses means the whole container should be tossed, as the mold can spread unseen. As a general rule, black or dark red mold on any cheese is a sign to throw it away; it can be toxic.
Beyond Mold: Recognizing Other Signs of Spoilage
While mold is easy to spot, other spoilage signs can be less obvious. Cheese, despite its sometimes strong flavors and odors, should have a consistent taste and smell. If your cheese develops a kerosene or Band-Aid-like flavor, it’s an indication that mold might have penetrated the cheese, and it should be discarded. Changes in color, texture, sliminess, or watery residue are also red flags for spoilage.
Storing Cheese for Success
Proper storage is crucial to prevent unwanted mold growth. Hard cheeses can last for three to four weeks after opening when stored correctly, while soft cheeses typically last about a week. The crisper drawer of your refrigerator is the ideal spot for cheese storage. Wrap it in cheese paper or wax paper to minimize moisture, which can encourage mold. Avoid plastic containers or plastic wrap, as they can trap moisture. A plastic zip-top bag is a suitable alternative, but vacuum sealing is even better. Remember to store blue cheeses separately to prevent their mold from spreading to other cheeses. Regularly inspect your cheese, just as a cheese seller would. Cutting away any small mold spots that appear on a healthy cheese can help prolong its life.
By understanding the nuances of mold and cheese, you can enjoy your cheese safely and savor its delicious flavors. Remember to pay attention to the visual clues, the smell, and the taste of your cheese, and don’t hesitate to throw away any cheese that seems suspicious. Happy cheese eating!
