Queso fresco, Spanish for fresh cheese, is a popular Mexican cheese with a mild flavour and crumbly texture. It is traditionally made with raw cow's milk or a combination of cow and goat's milk. While it is a versatile cheese, it is not a melting cheese due to its high acid content. It can be softened with heat and used in dishes like quesadillas, burritos, and chiles relleños, but it will not melt or ooze like other cheeses. To get queso fresco to melt, one can use Rennet, an additive that helps cheese melt more easily.

What You'll Learn
Queso fresco is an acid-set cheese
Queso fresco is a Mexican cheese that is traditionally consumed fresh. It is a mild, milky, fresh cheese with a slightly sour taste. It is made with raw cow's milk or a combination of goat and cow milk. It is the most commonly used cheese in Mexican cooking.
Queso fresco is a pressed acid-set cheese, which means it will not age or melt. This makes it ideal for grilling or stir-frying. When heated, it becomes soft, but it is difficult to melt and may remain chunky. It is often used as a topping or garnish and can be crumbled over soups and salads or sliced and cubed for grilling.
Queso fresco is sometimes made with rennet and cultures, which may give it some meltability. However, it is generally considered a non-melting cheese, similar to paneer or feta.

Acid-set cheeses don't melt
Queso fresco is a Mexican cheese that is very popular in Mexican cooking. It is a mild, fresh cheese with a slightly sour taste, traditionally made with raw cow's milk or a combination of goat and cow milk.
Queso fresco is an acid-set cheese, which means that it is made by coagulating milk with the direct addition of an acid like lemon juice or vinegar. Acid-set cheeses are firm and do not melt because the acid causes the casein micelles to attract and aggregate together. While they may soften upon heating, they will not melt and become gooey and stretchy. Instead, they hold their shape and are, therefore, ideal for grilling or frying.
Queso fresco gets soft when heated, but it is difficult to melt. It may remain chunky or lumpy even when melted. It is still commonly used in cooking, especially as a topping or garnish for soups and salads, or as a filling for chiles rellenos, quesadillas, and burritos.
Other examples of acid-set cheeses include paneer, feta, goat cheese, and ricotta. These cheeses are also too acidic to melt well and will become grainy and hold their shape when heated. However, they are excellent for grilling or frying.

High heat causes cheese to curdle
Queso fresco is a Mexican cheese that is commonly used in Mexican cooking. It is a mild, fresh, white cheese that is traditionally made with raw cow's milk or a combination of goat and cow milk. This cheese is similar to feta and does not melt easily. When heated, it becomes soft but may remain chunky.
Queso fresco is an acid-set cheese, which means it is made by separating curds, straining them, and pressing them into a firm, fresh cheese. The acid causes the milk's protein to clump together and form curds. When cheese is heated, its fat liquefies and mixes with the water in the cheese. However, at the same time, the heat causes the proteins to coagulate and form a tangled network. If the cheese is heated for too long or at a high enough temperature, the protein network will ooze fat and water, causing the cheese to curdle.
To prevent cheese from curdling, it must be melted at a low temperature, ideally no higher than 160 to 170 degrees Fahrenheit. The cheese should also be shredded or grated to increase the surface area exposed to heat, allowing it to melt faster and at a lower temperature.

Rennet-set cheeses melt more easily
Queso fresco is a Mexican cheese that is commonly used in Mexican cooking. It is a mild, fresh cheese with a tangy flavour, traditionally made with raw cow's milk or a combination of goat and cow milk. This cheese is usually consumed fresh, but it can be stored in the refrigerator by wrapping it tightly in plastic wrap.
Queso fresco is an acid-set cheese, which means it is created using an acid source such as lemon juice or vinegar. Acid-set cheeses do not melt because acid "dissolves the calcium glue that holds the casein proteins together in micelles". Therefore, when an acid-set cheese is heated, the proteins move closer together, and water is cooked off, but without the calcium holding everything together, the cheese will not melt.
Rennet-set cheeses, on the other hand, melt more easily. Rennet is a type of coagulant used in cheesemaking to separate milk into curds and whey. It is composed of a specific enzyme, chymosin, that is well-suited to separating the milk solids from the liquids. Rennet helps to form firm curds and is crucial in finding the right texture for the cheese. The most significant differentiator between types of rennet is their source, with animal and vegetable rennet being the most common. Animal rennet is traditionally sourced from the stomachs of unweaned ruminants, while vegetable rennet can be sourced from plants such as artichokes, thistle, and nettle, or the Mucor miehei fungus.
While rennet-set cheeses generally melt more easily than acid-set cheeses, there are exceptions. Some rennet cheeses do not melt, adding intrigue to the cheese world. Similarly, while queso fresco is an acid-set cheese that does not typically melt, it can be melted over low heat to make a dip or sauce, although it may remain chunky.

Queso fresco can be softened with heat
Queso fresco is a Mexican fresh cheese that is surprisingly easy to make at home. It is a type of queso blanco, or white cheese, made from cow's milk alone or from a combination of cow and goat milk, and acidified with rennet, lemon juice, or vinegar. The acid serves two purposes: it causes the milk to form curds and gives queso fresco its tangy flavor.
Queso fresco is soft, moist, and crumbly, making it perfect for sprinkling over antojitos (little snacks) and beans. It is most often crumbled and used as a garnish for all types of Mexican food: on top of enchiladas, inside of tacos, slathered on elote, over huevos rancheros, and on cooked black beans. It is also found in many Latin American and South American dishes, such as Colombian arepas and Dominican fried cheese.
Queso fresco gets soft when heated, but it is difficult to melt. You can melt it over low heat for a while to make a cheesy dip or sauce, but it may remain chunky. In its soft state, it is commonly used as part of a filling for chiles relleños (stuffed chiles), quesadillas, and burritos. It can also be used as a topping for soup; the heat from the soup will warm the cheese slightly.
Queso fresco is a pressed acid-set cheese, which means it won't age or melt. This makes it great for grilling or stir-frying. To make queso fresco at home, heat milk in a large pot over medium-low heat, stirring frequently, until it registers 165 to 185°F (74 to 85°C) on an instant-read thermometer. Add lemon juice or vinegar 1 tablespoon at a time, stirring gently after each addition.

Frequently asked questions
Queso fresco is a pressed acid-set cheese, which means it won't melt and is great for grilling.
If your queso fresco is lumpy, it may be due to the heat being too high, which causes the fat to separate from the solids.
To prevent lumpiness, stir the cheese on very low heat.
Other pressed acid-set cheeses like paneer, feta, and halloumi won't melt and can be used interchangeably with queso fresco.
To melt queso fresco, use rennet instead of an acidic agent like vinegar when making the cheese. Alternatively, you can use a different type of melting cheese such as Monterey Jack, queso asadero, or queso manchego.
