While making slime is a fun activity, it can sometimes go wrong and turn into a melty mess. This can happen due to various reasons, such as the slime being old, hot, or underactivated. To fix melted slime, one can try adding an activator slowly and carefully to prevent overactivation. Interestingly, cheese can also turn into slime when trying to make a cheese sauce, as the fats in the cheese separate from the milk. To avoid this, an emulsifying salt like sodium citrate can be added to create a proper emulsion. When it comes to choosing the best cheese for melting, options like Colby, Swiss, Smoked Gouda, and Cheddar are known to melt well. However, it's important to note that low-fat cheeses don't tend to melt as easily.

What You'll Learn
Low-fat cheeses don't melt well
While there are many cheeses that melt well, such as Colby, Swiss, and Gouda, low-fat cheeses do not tend to melt well. This is because the fats in cheese are not water-soluble, so when trying to melt low-fat cheese into milk, the fats will separate. While there are ways to force the fats to create the desired emulsion, such as using a roux or bechamel, low-fat cheeses will never melt in the same way as full-fat or reduced-fat cheeses.
Low-fat cheeses tend to be harder and more crumbly due to the lack of fat, which also affects their mouthfeel. The fat content of cheese is controlled by manipulating the fat content of the milk used to make it, and fat-free milk is created by removing the fat globules from regular milk. When making cheese, these fat globules are what allow the cheese to melt properly.
Some people have tried using cooking spray or canola oil on low-fat cheese to help it melt, with varying levels of success. Others have found that shredding the cheese or mixing it with other ingredients can help it melt somewhat, but it will never melt completely. For example, if you bake a casserole using fat-free cheese, the cheese inside may melt somewhat, while the cheese on top will only brown without melting.
The type of cheese also makes a difference in how well low-fat versions melt. For instance, fat-free ricotta and mozzarella are said to be more successful than fat-free cheddar and Monterey jack, which have a different mouthfeel and may take some getting used to. Ultimately, if melting the cheese is the goal, it is best to avoid low-fat or fat-free cheeses altogether.

Add acid to break up protein strands
While my search did not yield any information on the best cheese for making slime, I did find some relevant information on the process of cheese melting, which may be useful in your slime-making process.
Cheese is mostly composed of protein, fat, and water. The casein protein forms a 3-D mesh that has calcium acting as the "glue" holding the casein micelles together. The acid level in the cheese is one of the biggest factors that influence how well a cheese melts and stretches. Acid development dictates how much calcium is removed from the casein matrix and how strongly the caseins will associate with each other. With time, proteins can break down (proteolysis) and get chopped up, affecting the stretch of the cheese. Acid is often produced and proteins break down as cheese ages, impacting how the cheese melts.
Cheesemakers add acid directly or add cultures (bacteria) that produce acid. Some cheeses, like cottage cheese and chèvre, are made by coagulating milk with the direct addition of acid. In these cheeses, the acid causes the casein micelles to attract and aggregate together, meaning the cheese won't melt very well.
When making cheese sauce, the goal is to fully incorporate cheese into milk. However, the fats in the cheese are not water-soluble, so melting cheese into milk will cause the fats to separate. To create a proper emulsion that keeps the fats bound to the milk, you can use sodium citrate, an emulsifying salt. Processed cheese products like American cheese and cheese whiz melt better than real cheese because they are packed with these emulsifying salts.
Therefore, to break up the protein strands in cheese to make slime, you can add acid. For example, you can add lemon juice, as suggested by a user on Reddit who accidentally turned their cheese sauce into slime. Additionally, you can add an acid like vinegar to milk to cause the milk's protein, casein, to separate from the liquid, as demonstrated in a slime recipe using milk, vinegar, and baking soda.

Sodium citrate helps create a proper emulsion
While searching for the best cheese to melt for slime, I found that there are a variety of cheeses that melt well, such as Colby, Swiss, and Gouda. However, I also came across several instances of people accidentally creating slime while trying to make cheese sauce. This issue can be mitigated with the use of sodium citrate.
Sodium citrate is an emulsifying salt. When making cheese sauce, the goal is to fully incorporate cheese into milk. The fats in the cheese are not water-soluble, so melting cheese into milk will cause the fats to separate. Therefore, it is necessary to create a proper emulsion that keeps the fats bound to the milk and stable. Sodium citrate is a compound that accomplishes this perfectly.
On a molecular level, cheese can be thought of as a three-part network consisting of fat, calcium, and casein protein. Calcium acts as an adhesive that binds the proteins together, but these proteins do not interact with the fat. When cheese is heated, the fat leaks out of the weakened protein structure, resulting in an oily texture.
Sodium citrate acts as an emulsifier, allowing the proteins in the cheese to become more soluble and creating a smooth emulsion without curdling. It reduces the cheese's acidity and prevents it from separating, resulting in a smooth and creamy texture. The thickness of the sauce can be controlled by adjusting the ratio of liquid to cheese.
To create a cheese sauce with sodium citrate, start by slowly warming the liquid and whisking in the sodium citrate. Bring it to a gentle simmer, then whisk again to ensure the sodium citrate has completely dissolved. Gradually add your cheese, continuing to whisk until it has melted. With sodium citrate, you can use any cheese or combination of cheeses, as it helps create a smooth and stable emulsion.

Processed cheese melts better due to emulsifying salts
When it comes to slime, creating a cheese sauce that melts smoothly requires addressing the issue of fat separation. Cheese fats are not water-soluble, so melting cheddar cheese into milk will cause the fats to separate. This is where emulsifying salts, such as sodium citrate, come into play.
Emulsifying salts are the key to creating a stable emulsion that keeps the fats bound to the milk. Processed cheese, including American cheese, cheese whiz, and nacho cheese, is packed with these emulsifying salts, which is why it melts much better than real cheese.
To understand why processed cheese melts better, let's delve into the role of emulsifying salts. These salts help create a proper emulsion by keeping the fats in the cheese bound to the milk, preventing separation. This is especially important when trying to melt cheese into milk to create a cheese sauce.
While traditional methods like using a roux or bechamel can force the fats to emulsify with the right ingredients and heat, emulsifying salts like sodium citrate accomplish this more effectively and simply. This is why processed cheese, with its higher content of emulsifying salts, tends to melt more smoothly and is often the preferred choice for creating slime or cheese sauces.
In summary, processed cheese melts better due to the presence of emulsifying salts, which create a stable emulsion and prevent fat separation when melted. This knowledge can be useful when creating slime or cheese sauces, ensuring a smoother and more desirable consistency.

Older cheddars melt better
When it comes to slime-making, the type of cheese you choose can impact the melting quality of your final product. While different types of cheese can be used, older cheddars tend to melt better, resulting in a smoother and more supple texture.
The ageing process of cheddar cheese plays a crucial role in its melting ability. As cheddar ages, its flavour becomes sharper and more pronounced. This ageing process also affects the cheese's texture, making it softer and easier to melt. Older cheddars have had more time to develop a richer flavour and a creamier consistency, contributing to their superior melting qualities.
Additionally, the fat content in cheese is a critical factor in determining its melting ability. Cheeses with higher fat content tend to melt more smoothly. Older cheddars often have a higher fat content than younger ones, as they have undergone a longer ageing process, allowing the cheese to mature and develop a more buttery texture.
Furthermore, the protein structure in older cheddars has had more time to break down, resulting in a softer texture. This breakdown of proteins makes the cheese more pliable and easier to melt, contributing to its superior melting qualities.
When selecting a cheddar for slime-making, it is recommended to choose at least a medium-aged variety. Younger cheddars may not have developed the full range of flavours and textures that make older cheddars ideal for melting. However, it is important to note that while older cheddars melt better, they can also be more pungent and intense in flavour, so finding the right balance between age and flavour preference is essential.
