Ricotta cheese is a versatile ingredient that can be used in both sweet and savoury dishes. It is a type of whey cheese that is made by coagulating milk with acids or enzymes, resulting in a creamy texture. When heated, ricotta cheese does not melt in the same way as other cheeses due to its unique protein structure. Instead, it can curdle and become elastic, which makes it unsuitable for melting or cooking at high temperatures. However, it can be used as a delicious sauce for pasta when blended with ingredients like garlic, Parmesan, milk, salt, and pepper. The key to achieving a smooth and creamy texture is to use fresh, thick, whole milk ricotta and blend it with other ingredients at a low temperature.

What You'll Learn
Ricotta cheese doesn't fully melt
Ricotta cheese is made from whey, the liquid left over from making cheese. This means that ricotta contains a little casein but consists mostly of whey proteins that form permanent bonds between sulfur molecules. These permanent bonds make it difficult to melt ricotta, and it only softens.
The protein structure of ricotta differs from that of other cheeses. While most cheeses consist predominantly of casein, a type of protein, ricotta is a whey cheese. After the casein is extracted from the milk, the remaining proteins solidify into an unmeltable tangle of molecules.
The quality of ricotta cheese can also affect its melting capability. Cheaper ricottas may use gums and stabilizers to cut corners and increase profit margins, resulting in a grainy texture after cooking. Higher-quality ricottas, on the other hand, are made with just milk, a bit of acid, and salt, allowing for better melting.
Additionally, the brand of ricotta cheese can impact its melting ability. Some brands may create cheese with smaller protein clumps that are less noticeable when heated, resulting in a smoother texture. Changing brands can lead to variations in the size of protein clumps, affecting the overall melting consistency.
In conclusion, ricotta cheese doesn't fully melt due to its unique protein structure, quality, and brand variations. Its high whey protein content forms permanent bonds that resist melting, resulting in a softening of the cheese rather than a complete melt.

Use fresh, thick whole milk ricotta
Ricotta cheese is a versatile ingredient that can be used in a variety of dishes, from savoury to sweet. When it comes to melting ricotta cheese, it's important to note that it doesn't melt in the same way as other cheeses. Ricotta is a whey cheese made from protein clumps that form an unmeltable tangle when heated. This is why you might sometimes end up with "cheese crumbs" in your dish, even after applying heat.
To get the most out of your ricotta cheese, especially if you're using it in a sauce, it's recommended to use fresh, thick whole milk ricotta. The skim milk variety tends to be too thin and watery, which can affect the consistency of your dish. When making a sauce, you can blend ricotta cheese with ingredients like garlic, Parmesan, milk, salt, pepper, and red pepper flakes to create a smooth and creamy texture. This type of sauce is best served cold over hot pasta or warmed bread to avoid curdling.
When purchasing ricotta cheese, it's worth checking the ingredients. High-quality ricottas are made with just milk, a bit of acid, and salt, while cheaper varieties may contain gums and stabilizers that can affect their melting ability and leave a grainy texture after cooking.
If you're using ricotta cheese as a topping for dishes like pasta bakes or lasagne, dollops of fresh, thick whole milk ricotta can be added before baking. However, keep in mind that ricotta won't melt and blend into the dish the same way other cheeses do, so you may still have distinct clumps of cheese in your final dish.
In summary, when using ricotta cheese, especially in sauces, opt for fresh, thick whole milk ricotta for the best flavour and texture. Avoid heating ricotta directly, as it can curdle, and instead, incorporate it into cold sauces that can be served over hot dishes.

Avoid stabilisers and gums in ricotta
Ricotta is a whey cheese, which means that after the casein is extracted from the milk, the remaining proteins can only be solidified by clumping the molecules together. This creates a tangled structure that does not melt. While some cheeses with a similar composition can be melted, ricotta's protein structure is different and does not respond to heat in the same way.
Some manufacturers add gums and stabilisers to their ricotta, which can affect the taste and texture of the cheese. These additives are used to firm up the cheese and prevent water from separating out of the dairy product. However, they can result in a grainy texture when the cheese is cooked, as stabilisers do not hold up well to heat.
To avoid stabilisers and gums in your ricotta, check the ingredients list. The best ricottas will only contain milk (and/or whey), salt, and vinegar. Recommended brands that do not use stabilisers and gums include Organic Valley, Calabro, and Biazzo.
If you are unable to find a brand without stabilisers and gums, you can still use it, especially if you are adding toppings to your dish. You may need to add a small amount of milk and lemon juice to improve the texture.

Ricotta's protein structure differs from other cheeses
Ricotta is an Italian whey cheese made from the whey left over from the production of other cheeses. It is made by coagulating the proteins that remain after the casein has been used to make cheese. The acid added causes further whey protein denaturation as well as the caseins to begin to coagulate. The confluence of these processes creates the soft mixture we know as ricotta.
The whey that ricotta is made out of contains high amounts of whey proteins. These proteins are very different from the casein proteins that are typically used in cheesemaking. Whey proteins are much more susceptible to heat coagulation. The combination of low pH and high temperature denatures the protein and causes it to flocculate, forming a fine curd.
The production of ricotta in the Italian peninsula dates back to the Bronze Age. In the second millennium BC, ceramic vessels called milk boilers started to appear frequently and were apparently unique to the peninsula. These were designed to boil milk at high temperatures and prevent the milk from boiling over. The fresh acid-coagulated cheeses produced with these boilers were probably made with whole milk.

Serve ricotta sauce cold to avoid curdling
When it comes to ricotta cheese, it's important to remember that it is a delicate ingredient that can easily curdle if not handled properly. To avoid this, it is best to serve ricotta sauce cold. Ricotta cheese has a tendency to curdle when heated, especially if it is subjected to rapid or high heat. This is because ricotta is a soft, fresh cheese with a high moisture content, and like most fresh cheeses, it doesn't melt smoothly like aged cheeses. When ricotta is heated, the proteins clump together, causing the cheese to separate and form curds. By keeping the sauce cold, you minimize the risk of curdling and ensure a smooth, creamy texture.
There are several ways to do this, and one is to make sure that the ricotta sauce is thoroughly chilled before serving. This can be achieved by preparing the sauce in advance and allowing it to cool completely in the refrigerator. If you're making a hot dish with ricotta sauce, such as lasagna, let the dish cool down for a few minutes before serving. This will allow the ricotta sauce to thicken and set, reducing the chances of it curdling. Additionally, when reheating dishes containing ricotta, do so over low heat or in short intervals to avoid overheating the sauce.
Another way to serve ricotta sauce cold is to incorporate cold ingredients. For example, if your sauce includes vegetables, cook them separately and add them to the sauce while they're still cold. This will help bring down the overall temperature of the sauce and reduce the risk of curdling. Also, consider serving the ricotta sauce separately from the main dish. This way, you can keep the sauce chilled until the very last moment, adding a refreshing contrast to a hot meal.
Additionally, the type of ricotta cheese you use can make a difference. There are various types of ricotta cheese available, ranging from whole milk to part-skim and full-skim varieties. The higher the fat content, the less likely it is to curdle, so opting for whole milk ricotta can improve the texture and stability of your sauce. Furthermore, some recipes may call for draining the ricotta before using it to reduce the moisture content and improve its texture. However, this step may not be necessary for all dishes, especially if you prioritize convenience and a faster preparation time.
Finally, when stirring ricotta sauce, do so gently. Vigorous stirring can break down the cheese and encourage curdling. Use a gentle folding motion instead, and avoid using high-heat tools like immersion blenders, which can increase the risk of curdling. Following these tips will help you serve ricotta sauce cold, preventing curdling and ensuring a delicious, smooth texture that complements your dishes perfectly.
