How to Keep it Fresh: Properly Storing Mozzarella Cheese
To best store mozzarella cheese, whether fresh, low-moisture, or shredded, it’s crucial to maintain appropriate moisture levels and cool temperatures. Fresh mozzarella must be submerged in its liquid, while low-moisture varieties should be tightly wrapped and refrigerated, and shredded mozzarella requires an airtight container or resealable bag.
Mozzarella: A Cheese for All Occasions
Mozzarella cheese, a culinary cornerstone, boasts a rich history and versatile applications. Originating in Italy, it has captivated palates worldwide. But its unique characteristics demand careful storage to preserve its delightful flavor and texture. Understanding the different types of mozzarella and their specific storage needs is essential for any cheese lover.
Understanding Mozzarella Types
Mozzarella isn’t a one-size-fits-all cheese. From the delicate, milky fresh mozzarella to the drier, shelf-stable low-moisture versions, knowing the distinctions is key to proper storage.
- Fresh Mozzarella (Fior di Latte and Buffalo Mozzarella): This is the most perishable type. Made with either cow’s milk (Fior di Latte) or water buffalo milk (Buffalo Mozzarella), it’s characterized by its soft texture, high moisture content, and delicate flavor.
- Low-Moisture Mozzarella: Commonly used on pizzas and in baked dishes, this type has a lower moisture content, giving it a longer shelf life. It’s often sold in blocks or pre-shredded.
- Smoked Mozzarella (Affumicata): This type is smoked, imparting a distinct smoky flavor. The smoking process also helps to extend its shelf life somewhat.
- Burrata: While technically not mozzarella in the strictest sense, Burrata is a fresh mozzarella shell filled with stracciatella (shredded mozzarella curd) and cream. It requires even more careful handling than fresh mozzarella.
The Importance of Proper Storage
Improper storage can lead to several undesirable consequences:
- Spoilage: Bacterial growth can lead to mold, off-flavors, and an unpleasant smell.
- Textural Changes: Mozzarella can become rubbery, dry, or excessively soft.
- Flavor Degradation: The delicate flavors of fresh mozzarella can be lost or altered.
- Reduced Shelf Life: Properly stored mozzarella will last longer, reducing waste.
Storing Fresh Mozzarella
Fresh mozzarella, due to its high moisture content, requires specific storage conditions:
- Always keep it submerged in its liquid (whey or water). This prevents the cheese from drying out and helps maintain its texture and flavor.
- Store it in the refrigerator at a temperature between 35°F (2°C) and 45°F (7°C).
- Use a container with a tight-fitting lid. If the original liquid is cloudy or has an off-putting smell, replace it with fresh, cold water. Change the water daily.
- Consume it as soon as possible. Fresh mozzarella is best enjoyed within a few days of purchase.
Storing Low-Moisture Mozzarella
Low-moisture mozzarella is more forgiving but still needs proper care:
- Wrap it tightly in plastic wrap or beeswax wrap. This prevents it from drying out.
- Store it in the refrigerator at a temperature between 35°F (2°C) and 45°F (7°C).
- Consider vacuum-sealing for extended storage. This removes air, further preventing spoilage.
- Once opened, use it within a week or two.
Storing Shredded Mozzarella
Shredded mozzarella is convenient but more prone to drying out and clumping:
- Store it in an airtight container or a resealable bag.
- Remove as much air as possible from the bag before sealing it.
- Consider adding a sprinkle of cornstarch or potato starch. This helps to prevent clumping.
- Store it in the refrigerator at a temperature between 35°F (2°C) and 45°F (7°C).
- Use it within a week or two of opening.
Common Mozzarella Storage Mistakes
Avoiding these common mistakes will help keep your mozzarella in top condition:
- Leaving Fresh Mozzarella Out of Its Liquid: This is a surefire way to dry it out.
- Storing Mozzarella at Room Temperature: Mozzarella should always be refrigerated.
- Not Wrapping Low-Moisture Mozzarella Properly: Air exposure leads to drying.
- Freezing Fresh Mozzarella: This drastically alters the texture, making it crumbly and watery. Freezing low-moisture mozzarella is acceptable, but can still change the texture.
- Ignoring Expiration Dates: Always check and adhere to the “use by” or “sell by” date.
- Contamination: Cross-contamination with other foods can lead to spoilage. Always use clean utensils and cutting boards.
Understanding Shelf Life
The shelf life of mozzarella varies depending on the type:
| Type of Mozzarella | Storage Method | Shelf Life (Approximate) |
|---|---|---|
| Fresh Mozzarella | Submerged in liquid | 3-5 days |
| Low-Moisture Mozzarella | Tightly wrapped | 2-3 weeks |
| Shredded Mozzarella | Airtight container/bag | 1-2 weeks |
Recognizing Spoilage
Be vigilant in identifying signs of spoilage:
- Off-odor: A sour, ammonia-like, or otherwise unpleasant smell.
- Slimy texture: A sticky or slippery surface.
- Mold growth: Any visible mold, regardless of color.
- Discoloration: Any unusual discoloration, especially pink, brown, or green.
If any of these signs are present, discard the cheese immediately. It’s better to be safe than sorry when it comes to food safety.
FAQs About Storing Mozzarella Cheese
How can I tell if my fresh mozzarella is still good?
The best way to tell if fresh mozzarella is still good is to check the liquid it’s stored in. If the liquid is cloudy, smells sour, or the cheese has a slimy texture, it’s likely spoiled. Always err on the side of caution and discard if you are unsure.
Can I freeze mozzarella cheese?
While not ideal, low-moisture mozzarella can be frozen. Freezing alters the texture, making it more crumbly. It’s best to shred it before freezing and use it in cooked dishes. Fresh mozzarella is not recommended for freezing as it becomes very watery and loses its desirable texture.
What’s the best way to thaw frozen mozzarella?
The best way to thaw frozen mozzarella is to slowly thaw it in the refrigerator overnight. This helps to minimize moisture loss. Using it in cooked applications is always recommended after freezing.
How long can I keep opened low-moisture mozzarella in the refrigerator?
Once opened, low-moisture mozzarella should be wrapped tightly in plastic wrap and stored in the refrigerator for up to two weeks. Make sure it’s showing no signs of spoilage, such as discoloration or bad odor.
Is it okay to eat mozzarella that has a slightly sour smell?
A slightly sour smell can be normal for some types of mozzarella, especially fresh varieties. However, if the smell is strong or accompanied by other signs of spoilage, such as a slimy texture or discoloration, it’s best to discard the cheese.
Can I reuse the liquid that fresh mozzarella is stored in?
The liquid that fresh mozzarella is stored in, also known as whey, can sometimes be reused in recipes like ricotta making, but should be used almost immediately. It is not recommended to simply reuse the same liquid for mozzarella storage. Replace the water daily.
What’s the ideal temperature for storing mozzarella cheese?
The ideal temperature for storing mozzarella cheese, regardless of type, is between 35°F (2°C) and 45°F (7°C). This range helps to slow down bacterial growth and maintain the cheese’s quality.
How can I prevent my shredded mozzarella from clumping together?
To prevent shredded mozzarella from clumping, toss it with a small amount of cornstarch or potato starch before storing it in an airtight container or resealable bag. Remove as much air as possible from the bag before sealing.
My mozzarella has a slightly rubbery texture. Is it still safe to eat?
A slightly rubbery texture can occur if mozzarella has been stored for too long or exposed to air. If there are no other signs of spoilage, such as a bad odor or discoloration, it is likely still safe to eat, but the quality may be diminished.
Can I store mozzarella cheese in a vacuum-sealed bag?
Yes, vacuum-sealing is an excellent method for storing both low-moisture and shredded mozzarella. It removes air, preventing oxidation and slowing down spoilage. It’s not recommended for fresh mozzarella.
What’s the best way to store Burrata cheese?
Burrata cheese, being even more delicate than fresh mozzarella, should be stored exactly as fresh mozzarella: submerged in its liquid, refrigerated, and consumed within 24-48 hours of purchase for optimal flavor and texture.
What if my mozzarella cheese develops a yellow tint?
A slightly yellow tint on mozzarella can occur naturally, especially with buffalo milk mozzarella. However, if the yellowing is excessive or accompanied by other signs of spoilage, it’s best to discard the cheese. Always check the smell and texture first.
