Parmesan cheese is a versatile ingredient used in a variety of dishes. It is typically sold in blocks, shredded, or grated forms. While the shredded and grated varieties are convenient, they are not always the same as freshly grated cheese. Pre-shredded cheese often contains additives to prevent clumping, which can affect its performance and taste. Freshly grated Parmesan, for example, is finer and melts more easily into dishes, providing a stronger flavour. However, shredded Parmesan is ideal for creating thicker layers of cheese in dishes like pizzas and casseroles.

What You'll Learn

Grated parmesan can be made from parmesan or romano cheese
Grated Parmesan cheese can be made from either Parmesan or Romano cheese. It is important to note that unless the packaging specifically states that it is made from Parmesan, it may not be "real" Italian Parmesan cheese.
Parmesan cheese, known as Parmigiano Reggiano in Italian, is typically sold in a solid block, shredded, or grated form. The type of Parmesan cheese used depends on the specific recipe and the desired texture and flavour. Grated Parmesan cheese is much finer and similar to powder, while shredded Parmesan cheese comes in thick shreds or strips that can vary in thickness depending on the manufacturing process.
Shredded Parmesan cheese is ideal for creating thicker layers of cheese on dishes such as sandwiches, quesadillas, pizzas, casseroles, and baked pasta. It provides a more prominent cheese flavour and a gooey texture. On the other hand, grated Parmesan is perfect for garnishing pasta dishes or adding a subtle cheese flavour to sauces and soups. It blends seamlessly into dishes, enhancing the overall flavour without overpowering it.
The difference in shape and texture between shredded and grated Parmesan cheese leads to variations in their performance and functionality in recipes. For example, shredded Parmesan may not fully melt into sauces or pizza toppings, resulting in a less cohesive dish. Freshly grated cheese is also believed to have a superior taste compared to pre-shredded cheese due to the absence of added ingredients and preservatives. Pre-shredded cheese often contains anti-clumping agents and desiccants, which can affect its melting properties and overall sensory experience.
Additionally, the cost and shelf life differ between freshly grated and pre-shredded cheese. Grating a block of cheese yields approximately twice as much cheese by volume compared to purchasing a pre-shredded bag of the same weight. Moreover, block cheese can be stored for several weeks, whereas shredded cheese should be used or frozen within a few days of opening.

Pre-shredded cheese has additives to prevent clumping
Pre-shredded cheese is a convenient option for those short on time or looking to reduce food waste. However, it's worth noting that this convenience comes at a cost: pre-shredded cheese often contains additives to prevent clumping and extend shelf life.
One common additive is cellulose, a tasteless, ultra-fine powder derived from wood or cotton pulp. While cellulose is not harmful, it can affect the texture and melting properties of the cheese. It does this by absorbing moisture, resulting in a drier texture and inhibiting the cheese's ability to melt smoothly. This can lead to a less desirable texture in dishes like macaroni and cheese, where a creamy, stringy cheese sauce is desired.
Other anti-caking agents used in pre-shredded cheese include potato starch, cornstarch, and calcium sulfate. Potato starch acts as a thickener and has anti-clumping properties, while calcium sulfate is commonly used in building materials like cement and tiles. These additives can also create a barrier to flavor, impacting the overall taste of the cheese.
Additionally, pre-shredded cheese often contains natamycin, an anti-mold agent used to prevent the growth of mold and extend the shelf life of the product. While natamycin is considered safe for consumption, its presence can further alter the melting properties of the cheese.
The use of these additives may explain why some recipes specifically call for "freshly grated" cheese. Grating your own cheese from a block can result in a smoother melt and a more intense flavor, though it does require additional time and effort. Ultimately, the decision to use pre-shredded or freshly grated cheese depends on the specific needs and preferences of the individual.

Freshly grated cheese may taste better
Secondly, the process of shredding the cheese introduces more surface area, which can affect the taste and texture. The increased surface area can lead to a drier product, and the smaller shreds may not provide the same satisfying bite as larger shavings of freshly grated cheese. This is especially true for hard cheeses like Parmesan, which are already dry and can become even drier when pre-shredded and treated with desiccants.
Additionally, freshly grated cheese may offer a purer and fuller flavor due to the absence of added ingredients. While the desiccants used in pre-shredded cheese are said to be tasteless, they still make up a small portion of the product and could potentially impact the overall taste.
Furthermore, freshly grated cheese can be more cost-effective and have a longer shelf life than pre-shredded cheese. When grating a block of cheese, one can yield almost twice the volume of shreds compared to buying a pre-shredded bag of the same weight. This means that not only does freshly grated cheese go further in recipes, but it also lasts longer in the refrigerator, reducing food waste.
Lastly, the act of grating one's own cheese can be a satisfying and sensory experience. The aroma of freshly grated cheese can enhance the overall enjoyment of the product, and the tactile nature of grating can connect individuals to the food they are preparing.

Shaved parmesan may be better quality
Shaved Parmesan also has a different mouthfeel than grated or shredded Parmesan. Smaller shreds or grated particles may provide more of a "bite" of concentrated flavor. Shaved Parmesan provides more cheesy goodness in a bite, as it has a larger surface area than grated or shredded cheese.
Shaved Parmesan is also more likely to be freshly grated, which may contribute to its higher quality. Freshly grated cheese has a longer shelf life than pre-shredded cheese, which manufacturers recommend using or freezing within a few days of opening. Freshly grated cheese also melts better than pre-shredded cheese, which contains additives to prevent clumping that can interfere with melting.
Finally, shaved Parmesan may be of higher quality because it is more likely to be authentic Parmigiano-Reggiano. Authentic Parmigiano-Reggiano is made from cow's milk from cows that eat fresh grass and hay. It has a rich aroma and distinctively granular texture and is aged for a minimum of 18 months to deliver an authentic sweet, nutty flavor.

Grated cheese is better for garnishes
Grated cheese is better suited for garnishes than shredded cheese due to its fine texture, which allows it to blend seamlessly into dishes, enhancing the overall flavour. Its ability to meld into meals makes it ideal for garnishing pasta dishes, as it can be easily sprinkled on top and melted for a subtle cheesy note.
The key difference between shredded and grated cheese lies in their shape and texture. Shredded cheese comes in thick shreds or strips, which can vary in thickness, while grated cheese is much finer and resembles a powder-like consistency. This distinction influences how the cheese functions in recipes. Shredded cheese tends to deliver a prominent cheese flavour and a gooey texture, making it perfect for creating thick layers in sandwiches, quesadillas, pizzas, casseroles, and baked pasta dishes.
The anti-clumping agents used in pre-shredded cheese can affect its performance in recipes. These agents prevent the cheese from melting completely, resulting in a less-than-ideal texture. On the other hand, grated cheese, especially when freshly grated, offers a purer flavour and better melting qualities.
Additionally, freshly grated cheese has advantages in cost and shelf life. Grating a block of cheese yields approximately twice the amount of shredded cheese by volume compared to buying a pre-shredded bag. Moreover, block cheese can be stored for weeks, outlasting pre-shredded cheese, which should be consumed or frozen within a few days of opening.
While grated cheese excels in garnishing and melting scenarios, it's important to remember that both shredded and grated cheese have their unique applications in the culinary world. Each type of cheese preparation has its place, depending on the specific recipe and the desired outcome.
