Blue cheese. The mere mention of it can elicit strong reactions, ranging from ecstatic delight to utter disgust. Its pungent aroma, sharp, salty flavor, and distinctive blue veins are either embraced with open arms or vehemently rejected. But what is it about this particular type of cheese that makes it so polarizing? Why do some people consider it a culinary masterpiece while others find it utterly repulsive? Let’s delve deep into the world of blue cheese, exploring its origins, production methods, flavor profile, and the psychological factors that contribute to its divisive nature.
Understanding Blue Cheese: More Than Just Mold
At its core, blue cheese is a semi-soft cheese characterized by its blue or blue-green veins of mold. These veins are not a sign of spoilage; rather, they are the result of injecting the cheese with specific strains of Penicillium mold during the production process. This mold is responsible for the cheese’s distinctive flavor and aroma.
The Science Behind the Stink
The characteristic odor of blue cheese comes from a complex blend of volatile organic compounds produced by the Penicillium molds. These compounds include ketones, aldehydes, and esters, many of which have strong, pungent aromas that some find off-putting. Among these, methyl ketones are often cited as contributing to the “stinky socks” or “barnyard” smell that some associate with blue cheese. The concentration and specific types of these compounds vary depending on the strain of Penicillium used, the type of milk, and the aging process, resulting in a wide range of flavor profiles among different blue cheeses.
A Global Affair: Different Types of Blue Cheese
Blue cheese is not a monolithic entity. It encompasses a wide variety of cheeses produced in different regions using various techniques and types of milk. Some of the most well-known include:
- Roquefort: Perhaps the most famous blue cheese, Roquefort is made from sheep’s milk and aged in the natural caves of Roquefort-sur-Soulzon, France. Its unique terroir contributes to its distinctive flavor.
- Gorgonzola: This Italian blue cheese is made from cow’s milk and comes in two varieties: Dolce (sweet) and Piccante (spicy).
- Stilton: A classic English blue cheese, Stilton is also made from cow’s milk and has a Protected Designation of Origin (PDO) status.
- Danish Blue (Danablu): A strong and creamy blue cheese made from cow’s milk.
- Bleu d’Auvergne: A French blue cheese made from cow’s milk with a strong and pungent flavor.
Each type of blue cheese has its own unique characteristics, influenced by the type of milk used, the specific strain of Penicillium employed, and the aging process. This diversity contributes to the wide range of opinions surrounding blue cheese, as some may find one type palatable while disliking another.
The Flavor Factor: Why Some Love It, and Others Loathe It
The flavor of blue cheese is complex and multifaceted. It’s a combination of salty, tangy, sharp, and sometimes even sweet notes. The Penicillium mold breaks down fats and proteins in the cheese, creating a range of flavor compounds that contribute to its unique taste.
The Role of Salt
Salt plays a crucial role in the flavor of blue cheese. It inhibits the growth of undesirable bacteria, controls the activity of the Penicillium mold, and enhances the overall flavor profile. The saltiness can be quite pronounced in some blue cheeses, which can be off-putting to those who are sensitive to salt.
The Tangy Undertones
The tangy flavor of blue cheese comes from the presence of lactic acid, which is produced during the fermentation process. The amount of lactic acid present varies depending on the type of milk used and the production methods employed.
The Sharpness Defined
The sharpness of blue cheese is often attributed to the presence of free fatty acids, which are produced by the breakdown of fats by the Penicillium mold. These fatty acids can have a pungent and slightly bitter taste that contributes to the cheese’s overall sharpness.
The Unexpected Sweetness
While blue cheese is often associated with savory flavors, some varieties can also have a subtle sweetness. This sweetness comes from the breakdown of lactose, the sugar found in milk, into simpler sugars.
The Textural Element
Texture also plays a role in the perception of blue cheese flavor. Some blue cheeses are creamy and smooth, while others are crumbly and dense. The texture can influence how the flavors are perceived, with creamier cheeses often being perceived as milder and more approachable.
The Psychology of Taste: Why We Like What We Like
Taste is not simply a matter of biology; it’s also heavily influenced by psychology. Our personal preferences for certain foods are shaped by a complex interplay of genetic predisposition, cultural influences, and personal experiences.
The Genetic Factor
Studies have shown that genetics can play a role in our taste preferences. Some people are genetically predisposed to be more sensitive to certain tastes, such as bitterness, which may make them less likely to enjoy blue cheese.
The Cultural Influence
Cultural norms and traditions also play a significant role in shaping our taste preferences. In some cultures, blue cheese is a staple food, while in others it is relatively unknown. Exposure to blue cheese from a young age can increase the likelihood of developing a taste for it.
The Power of Experience
Personal experiences can also have a profound impact on our taste preferences. A negative experience with blue cheese, such as eating a particularly strong or poorly made cheese, can create a lasting aversion. Conversely, a positive experience can lead to a lifelong love of blue cheese.
The Neophobia Effect
Neophobia, the fear of trying new foods, can also contribute to the dislike of blue cheese. Many people are hesitant to try foods that look or smell unfamiliar, and blue cheese certainly falls into this category.
Is it Safe? Addressing Common Concerns About Mold
One of the biggest concerns people have about blue cheese is the presence of mold. Many people associate mold with spoilage and the potential for illness. However, the Penicillium mold used in blue cheese production is carefully selected and is considered safe for consumption.
The Difference Between Good Mold and Bad Mold
It’s important to distinguish between the Penicillium mold used in blue cheese and the types of mold that can grow on spoiled food. The Penicillium mold used in cheese production is specifically cultivated for its flavor-enhancing properties and is not harmful to humans. Spoilage molds, on the other hand, can produce toxins that can make you sick.
Proper Storage is Key
To ensure the safety and quality of blue cheese, it’s important to store it properly. Blue cheese should be wrapped tightly in plastic wrap or stored in an airtight container in the refrigerator. This will help to prevent the growth of undesirable molds and maintain its freshness.
When to Throw it Out
While the Penicillium mold in blue cheese is safe, it’s important to be aware of the signs of spoilage. If the cheese develops a fuzzy or slimy texture, or if it smells strongly of ammonia, it should be discarded.
Tips for Approaching Blue Cheese: A Gradual Introduction
If you’re curious about blue cheese but hesitant to try it, there are several ways to approach it that can increase your chances of enjoying it.
Start Mild
Begin with a milder blue cheese, such as Gorgonzola Dolce or a young Danish Blue. These cheeses have a milder flavor and a creamier texture, making them more approachable for beginners.
Pair it Wisely
Pair blue cheese with complementary flavors, such as fruits, nuts, and honey. The sweetness of the fruit and honey can help to balance the sharpness of the cheese.
Incorporate it into Dishes
Try incorporating blue cheese into dishes where its flavor is not the dominant element. For example, you could crumble it over a salad, melt it into a sauce, or add it to a pizza.
Trust Your Palate
Ultimately, whether or not you enjoy blue cheese is a matter of personal preference. Don’t feel pressured to like it if you don’t. However, if you’re willing to give it a try, you might just discover a new culinary favorite.
The Final Verdict: A Matter of Taste
The question of why blue cheese is so “bad” is subjective. It’s not inherently bad, but rather a matter of individual taste preferences shaped by a complex interplay of factors, including genetics, culture, and personal experiences. While its pungent aroma and sharp flavor may be off-putting to some, others find it to be a complex and delicious culinary experience. Understanding the science behind blue cheese, its diverse flavor profiles, and the psychology of taste can help to demystify this divisive cheese and perhaps even encourage a more open-minded approach to trying new foods. Ultimately, the decision of whether or not to embrace blue cheese is a personal one.
