Blue cheese, with its pungent aroma and tangy flavor, has been a staple in many cuisines around the world for centuries. From salad dressings to cheese plates, blue cheese adds a unique twist to any dish. However, with the rise of food allergies and dietary restrictions, many people are left wondering: does blue cheese have egg in it? In this article, we’ll delve into the world of blue cheese production, explore the role of eggs in cheese making, and provide a definitive answer to this question.
Understanding Blue Cheese Production
Blue cheese is a type of cheese that is made from cow’s, sheep’s, or goat’s milk. The production process involves several steps, including:
Milk Collection and Preparation
The first step in making blue cheese is to collect and prepare the milk. The milk is typically pasteurized to kill off any bacteria that may be present, and then it is mixed with a starter culture that contains bacteria such as Lactococcus lactis or Lactobacillus acidophilus. The starter culture helps to convert the milk sugar (lactose) into lactic acid, which gives the cheese its characteristic tangy flavor.
Curdling and Shaping
Once the milk has been mixed with the starter culture, it is left to sit for a period of time to allow the bacteria to grow and the milk to curdle. The curds (the solid parts of the milk) are then cut into small pieces and shaped into their desired form. For blue cheese, the curds are typically shaped into wheels or blocks.
Aging and Veining
The final step in making blue cheese is to age it. The cheese is left to sit in a controlled environment, such as a temperature- and humidity-controlled room, for several months. During this time, the cheese is regularly turned and rubbed with salt to prevent mold from growing on the surface. The cheese is also pierced with a skewer or needle to introduce oxygen, which helps to promote the growth of the blue-green mold (Penicillium roqueforti) that gives the cheese its distinctive veining.
The Role of Eggs in Cheese Making
Eggs are not typically used in the production of blue cheese. However, some cheese makers may use egg whites or egg yolks as a fining agent to help clarify the cheese and improve its texture. The egg whites or yolks are added to the milk before it is curdled, and they help to bind the curds together and create a smoother, more even texture.
Egg Whites as a Fining Agent
Egg whites are often used as a fining agent in cheese making because they contain proteins that help to bind the curds together. The egg whites are typically added to the milk in small quantities, and they help to create a stronger, more stable curd. This can be especially useful for cheeses that are prone to breaking or crumbling, such as blue cheese.
Egg Yolks as a Fining Agent
Egg yolks are also sometimes used as a fining agent in cheese making. The egg yolks contain lipids that help to enrich the flavor and texture of the cheese. However, egg yolks are not typically used in the production of blue cheese, as they can add a richness and creaminess that is not desirable in this type of cheese.
Does Blue Cheese Have Egg in It?
So, does blue cheese have egg in it? The answer is: it depends. While eggs are not typically used in the production of blue cheese, some cheese makers may use egg whites or egg yolks as a fining agent to help clarify the cheese and improve its texture. However, this is not a standard practice, and many blue cheeses are made without eggs.
Types of Blue Cheese That May Contain Eggs
Some types of blue cheese that may contain eggs include:
- Gorgonzola: This Italian blue cheese is sometimes made with egg whites or egg yolks to help clarify the cheese and improve its texture.
- Roquefort: This French blue cheese is sometimes made with egg whites to help bind the curds together and create a stronger, more stable curd.
Types of Blue Cheese That Do Not Contain Eggs
On the other hand, some types of blue cheese that do not typically contain eggs include:
- Stilton: This English blue cheese is made without eggs, and is instead characterized by its rich, tangy flavor and crumbly texture.
- Danish Blue: This semi-soft blue cheese is made without eggs, and is instead known for its mild, slightly sweet flavor and creamy texture.
Conclusion
In conclusion, while eggs are not typically used in the production of blue cheese, some cheese makers may use egg whites or egg yolks as a fining agent to help clarify the cheese and improve its texture. However, this is not a standard practice, and many blue cheeses are made without eggs. If you are allergic to eggs or have dietary restrictions, it is always best to check with the cheese maker or manufacturer to determine whether the blue cheese contains eggs.

By understanding the production process of blue cheese and the role of eggs in cheese making, you can make informed decisions about the types of blue cheese that are safe for you to eat. Whether you are a cheese aficionado or just a casual fan, there is a type of blue cheese out there for everyone.
Is blue cheese typically made with eggs?
Blue cheese is not typically made with eggs. The characteristic veining and strong flavor of blue cheese come from a type of mold, usually Penicillium roqueforti, that is introduced during the cheese-making process. This mold grows within the cheese as it ages, giving it a distinctive appearance and taste.
While some cheese recipes may include eggs, this is not a common practice in the production of blue cheese. The ingredients used to make blue cheese usually include milk, cheese cultures, salt, and the mold culture that gives the cheese its unique flavor and texture.
What gives blue cheese its distinctive veining?
The distinctive veining in blue cheese is caused by the growth of mold within the cheese. This mold, usually Penicillium roqueforti, is introduced during the cheese-making process and grows as the cheese ages. The mold breaks down the fats and proteins in the cheese, creating a strong, pungent flavor and a crumbly texture.
As the mold grows, it forms veins or streaks of blue-green mold throughout the cheese. This veining is a characteristic feature of blue cheese and is often considered a sign of the cheese’s quality and authenticity. The type and amount of mold used can affect the flavor and texture of the cheese, with some varieties having a stronger or milder taste.
Can people with egg allergies safely eat blue cheese?
In general, people with egg allergies can safely eat blue cheese, as it is not typically made with eggs. However, it’s always important to check the ingredients and manufacturing process to ensure that the cheese has not come into contact with eggs during production.
If you have a severe egg allergy, it’s a good idea to contact the manufacturer or consult with a healthcare professional before consuming blue cheese or any other food product. This can help you make an informed decision and minimize the risk of an allergic reaction.
How is blue cheese made?
Blue cheese is made using a process that involves introducing mold into the cheese during the cheese-making process. The milk is first curdled and then shaped into its desired form. The mold culture is then introduced, either by injecting it into the cheese or by applying it to the surface.
As the cheese ages, the mold grows and breaks down the fats and proteins, creating a strong, pungent flavor and a crumbly texture. The cheese is typically aged for several months, during which time it is regularly turned and monitored to ensure that the mold is growing evenly and that the cheese is developing the desired flavor and texture.
What types of milk are used to make blue cheese?
Blue cheese can be made from a variety of milks, including cow’s milk, sheep’s milk, and goat’s milk. The type of milk used can affect the flavor and texture of the cheese, with some varieties having a richer or creamier taste.
Cow’s milk is the most commonly used milk for making blue cheese, as it produces a milder flavor and a creamier texture. Sheep’s milk and goat’s milk, on the other hand, can produce a stronger, more pungent flavor and a crumblier texture.
Is blue cheese suitable for vegetarians?
Blue cheese is generally suitable for vegetarians, as it is typically made from milk and does not contain any animal products other than dairy. However, some vegetarians may be concerned about the use of animal rennet in the cheese-making process.
Animal rennet is an enzyme that is derived from the stomach lining of young animals and is used to help curdle the milk. However, many cheese manufacturers now use microbial rennet or plant-based rennet, which are suitable for vegetarians. If you’re a vegetarian, it’s a good idea to check the ingredients and manufacturing process to ensure that the cheese meets your dietary requirements.
Can blue cheese be made at home?
Yes, blue cheese can be made at home, but it requires some specialized equipment and a bit of patience. To make blue cheese, you’ll need a cheese mold, a cheese culture, and a mold culture, as well as a controlled environment for aging the cheese.
Making blue cheese at home can be a fun and rewarding process, but it’s not without its challenges. The cheese needs to be aged for several months, during which time it needs to be regularly turned and monitored to ensure that the mold is growing evenly and that the cheese is developing the desired flavor and texture. If you’re interested in trying your hand at making blue cheese, it’s a good idea to do some research and invest in a good cheese-making book or online course.
