Cheddar cheese is a semi-firm cheese that is prone to stickiness. This is due to the presence of proteins that tend to stick to each other when heated, resulting in a rubbery or stringy texture. The stickiness of cheddar can be influenced by factors such as temperature, the amount of cheese used, and the presence of additives or emulsifiers. Additionally, the aging process and the formation of crystals can contribute to the stickiness of cheddar cheese. While some stickiness is expected, excessive stickiness may indicate that the cheese is no longer suitable for consumption.

What You'll Learn
Cheddar's stickiness is due to its protein structure
The stickiness of cheddar cheese is a result of its protein structure. As cheese ages, it loses moisture and its protein structure contracts and stretches. This process of protein breakdown is called proteolysis, and it causes the amino acid chains that make up the protein structure to break up. This breakdown of amino acids is a normal part of the aging process, and it results in the formation of organic crystals, which can give cheese its famous crunchy texture.
Cheddar cheese, in particular, is known to develop calcium lactate crystals on its surface as it ages. These crystals can give the cheese a sticky texture, especially if the cheese is bandage-wrapped in cloth and a fat like butter or lard. The stickiness of cheddar cheese can also be attributed to the presence of milk proteins, which are negatively correlated with viscosity. In other words, as the amount of milk protein in cheddar cheese increases, the viscosity decreases, making the cheese more sticky and difficult to melt smoothly.
The type of cheese also plays a role in its stickiness. Cheddar cheese, for example, tends to be stickier than other types of cheese due to its higher milk protein content. When adding cheese to a liquid, it is important to add it gradually and at a lower temperature to prevent the cheese from melting all at once and sticking to itself. This is because the milk proteins in cheese tend to bind to one another and form a rubbery mass, which can be controlled by adding an emulsifier or an ingredient like sodium citrate.
In summary, the stickiness of cheddar cheese is influenced by its protein structure, the presence of milk proteins, and the aging process that leads to the formation of crystals. The type of cheese and the way it is incorporated into dishes can also impact its stickiness, with certain cheeses and preparation methods resulting in a rubbery or stringy texture.

Adding sodium citrate can reduce stickiness
Adding sodium citrate can reduce the stickiness of cheddar cheese. Sodium citrate is a salt derived from citric acid, and it can be easily made by combining baking soda and citric acid in water and then cooking it down. It is a common ingredient in pasteurized processed cheese products, acting as a potent emulsifying salt.
When making a cheese sauce, adding sodium citrate can help prevent the cheese from becoming rubbery or stringy and inhibit the milk proteins from binding to one another and forming a rubbery mass. This is achieved by disrupting the tightly knit protein structure, allowing for smoother and more cohesive melting. The amount of sodium citrate added can be adjusted to control the density and viscosity of the cheese sauce. For example, adding more liquid will result in a thinner sauce, while adding less liquid will make the sauce denser.
Sodium citrate is a useful ingredient for creating a smooth and velvety cheese sauce, as it acts as both an emulsifier and a stabilizer. It helps to keep the fat in the cheese from separating and prevents the cheese from splitting, even when exposed to high temperatures. This makes it a valuable tool for anyone looking to elevate their culinary creations and experiment with different cheese sauces.
Additionally, sodium citrate is versatile and can be used with any base liquid, such as milk, beer, or water, to create a cheese sauce tailored to individual preferences. It is also available in many stores or online, making it easily accessible for those who want to explore the world of cheese sauces.

Cheddar's stickiness is influenced by its age
The stickiness of cheddar cheese is influenced by various factors, including its age, temperature, humidity, and ventilation during the ageing process. The ageing process of cheddar cheese plays a crucial role in developing its sharpness, flavour, and texture.
Cheddar cheese is a well-known aged cheese, and its distinct sharp flavour and texture are a result of the ageing process. The ageing process can be influenced by factors such as temperature, humidity, and ventilation. The ideal temperature range for ageing cheddar is between 45-58°F (7-14°C), with a relative humidity of 75-95%. The sharpness of cheddar cheese varies from mild to extra sharp, and this is determined by the length of the ageing process. Mild cheddar, with its subtle and creamy taste, is aged for a shorter period of one to four months. During this initial stage of the ageing process, freshly made cheddar cheese is wrapped in cloth and left to rest for a few days. This allows the cheese to release whey and for mould to start growing on its surface.
Medium-aged cheddar, with a slightly stronger flavour, is typically aged for four to eight months. As cheddar continues to age, it loses moisture, intensifying its flavour and resulting in a higher melting point. This loss of moisture also contributes to the development of a crumbly texture in older cheddars.
For a properly sharp and mature cheddar, the ageing process extends to at least a year. Extra sharp cheddar, aged for two years or more, has a distinct crumbly texture and is best enjoyed on its own or with wine. The longer ageing process results in a more intense and complex flavour profile. Some cheesemakers take it even further, ageing their cheddar for multiple years. For example, the Hex 13 Year Aged Cheddar offers a sharp yet creamy and buttery flavour, complemented by a slightly crumbly texture and tiny crunchy tyrosine crystals that form during the extended ageing process.
In summary, the ageing process of cheddar cheese directly influences its flavour, texture, and stickiness. The length of the ageing process determines the sharpness and complexity of flavours, with older cheddars losing more moisture and developing a higher melting point. Proper temperature and humidity control during ageing are crucial to achieving the desired texture and preventing excessive mould growth.

Stickiness can be reduced by thinning the cheese
Stickiness in cheese is often caused by the milk proteins binding to one another and forming a rubbery mass. This can be prevented by using an emulsifier or adding an ingredient like sodium citrate, which is found in American cheese.
When it comes to thinning out cheese to reduce stickiness, there are several approaches you can take. One method is to add a thinning agent to the cheese. For example, when dealing with a thick cheese sauce, you can thin it out by adding a tablespoon of milk or reducing the heat. This will help you achieve your desired consistency.
Another strategy is to use a starch thickener like flour or cornstarch, which are popular kitchen staples. To do this, whisk together equal parts flour and cold water to create a slurry. Then, gradually stir the slurry into your cheese sauce until you reach the desired thickness. It's important to simmer the sauce for a few minutes to eliminate any raw flour taste.
Additionally, when working with shredded cheese, you can prevent clumping and stickiness by coating the cheese with a thin layer of cornstarch, cellulose, or potato starch. These ingredients absorb excess moisture, keeping the cheese loose and free-flowing.
Freezing shredded cheese is another effective way to prevent stickiness. While freezing may alter the texture of the cheese, it can be a useful option to extend the shelf life and maintain its loose consistency.

Adding cheese to hot pasta can make it sticky
To avoid sticky cheese, it is recommended to use a processed cheese with emulsifying and stabilising agents, such as American cheese slices. Alternatively, you can add sodium citrate to your sauce, which will prevent the cheese from splitting and sticking to itself. However, this may alter the flavour of your dish.
Another way to avoid sticky cheese is to focus on the pasta itself. Using pasta with lots of ridges and curls will help the cheese to cling on, rather than slide off. You can also add a small amount of starchy pasta water to your sauce, which will help it to stick to the pasta.
If you are making a pasta dish ahead of time, it is important to cool the pasta properly to avoid stickiness. Rather than running it under cold water or putting it into an ice bath, spread the cooked pasta out on a sheet tray and let it cool for 30 minutes before chilling it in the refrigerator. You can also lightly oil the pasta to prevent sticking.
