Buenos Aires, Argentina – In the vibrant culinary landscape of Buenos Aires, a city renowned for its rich gastronomic traditions, a remarkable innovation has emerged, challenging conventional perceptions of plant-based cuisine. During a recent fermentation workshop, this correspondent encountered a vegan cheese so exceptional, so profoundly "cheesy" in its essence, that it transcended mere imitation to stand as a culinary masterpiece in its own right. This revelation came courtesy of Nico Salguero, a talented student whose creation promises to redefine the standards for artisan vegan alternatives.

The pursuit of a truly authentic vegan cheese has long been a holy grail for plant-based enthusiasts and culinary innovators alike. Many attempts fall short, offering textures that are rubbery, flavors that are one-dimensional, or a disappointing lack of the complex umami and tangy notes characteristic of traditional aged dairy cheeses. Salguero’s almond-based creation, however, shattered these preconceptions, delivering a depth of flavor and a nuanced texture that rivaled, and arguably surpassed, many dairy counterparts. Its rich, savory profile and satisfying mouthfeel immediately captivated, signaling a significant breakthrough in the plant-based food movement.

Generously, Salguero shared the intricate details of his process, a method deeply rooted in the time-honored principles of fermentation and cheesemaking. His approach is not merely about substituting ingredients but about thoughtfully replicating the biological and chemical transformations that give traditional cheeses their distinctive character. This dedication to craft, combined with a profound understanding of plant-based ingredients, has culminated in a product that is not just a substitute, but a genuine culinary achievement.

The Genesis of a Culinary Revelation: An Encounter with Excellence

The moment of discovery unfolded within the dynamic atmosphere of a fermentation workshop, a setting dedicated to exploring the transformative power of microbes in food. Amidst discussions of lacto-fermentation and probiotic cultures, Nico Salguero presented his aged almond cheese. The initial visual appeal was striking: a beautifully formed wheel, bearing the subtle marks of careful handling and the promise of a well-aged product.

Upon tasting, the experience was immediate and profound. The cheese offered a firm yet yielding texture, reminiscent of a mature cheddar or a semi-hard artisanal cheese. But it was the flavor that truly distinguished it. A symphony of savory notes, a delicate tang, and an unmistakable umami depth danced on the palate, culminating in a finish that lingered pleasantly. There was no hint of the cloying sweetness sometimes found in nut-based cheeses, nor the artificiality that plagues many commercial vegan options. This was, unequivocally, a cheese experience, rich, complex, and utterly satisfying.

The initial reaction was one of surprise, followed by intense curiosity. How could a plant-based product achieve such an authentic "cheesy" character? Salguero’s explanation revealed a meticulous, multi-stage process that draws heavily from traditional cheesemaking techniques, adapting them ingeniously for plant-based ingredients. His method highlights the critical role of controlled fermentation, precise hydration, and extended aging – elements often overlooked in simpler vegan cheese recipes.

Unveiling the Masterpiece: Nico Salguero’s Artisanal Aged Almond Cheese

Salguero’s process is a testament to patience, precision, and an intuitive understanding of fermentation. It is a multi-day, multi-stage endeavor that transforms humble almonds into a sophisticated culinary delight. Each step is crucial, contributing to the final texture, flavor, and stability of the cheese.

Chronology of Creation: The Step-by-Step Process

The journey begins not with milk, but with carefully selected almonds, which serve as the rich, fatty base for this extraordinary cheese.

1. Soaking the Almonds (Approx. 24 Hours):
The initial step involves submerging raw almonds in water for approximately 24 hours. This crucial preliminary phase serves multiple purposes. Soaking softens the almonds, making them easier to process and enhancing their digestibility. Furthermore, it initiates the activation of enzymes within the nuts, which can begin to break down complex starches and proteins, preparing them for the subsequent fermentation stages. This process also helps to reduce phytic acid, an anti-nutrient found in nuts and seeds, thereby increasing the bioavailability of essential minerals.

2. Removing Skins:
Following the soak, the skins of the almonds are meticulously removed. While seemingly a minor detail, this step significantly contributes to the final texture and aesthetic of the cheese. Almond skins can introduce a slightly bitter note and contribute to a coarser texture. Their removal ensures a smoother, creamier paste, allowing the nuanced flavors of the fermented almond to shine through.

3. Sprouting the Soaked Almonds (Approx. 2 Days):
This is a pivotal stage that truly elevates Salguero’s cheese beyond simple nut-based spreads. The skinned almonds are allowed to sprout for about two days. During this period, they are kept moist through periodic rinsing but crucially drained to ensure adequate air circulation. Sprouting dramatically enhances the nutritional profile of the almonds, increasing enzyme activity, vitamin content, and further reducing anti-nutrients. More importantly for cheesemaking, sprouting alters the almond’s protein and carbohydrate structure, contributing to a unique flavor profile and a more complex substrate for fermentation. This step introduces a subtle freshness and vibrancy that sets the foundation for a truly dynamic flavor.

4. Grinding with a Fermented Starter (Thick Paste Consistency):
The sprouted almonds are then ground into a thick paste. The critical element at this stage is the incorporation of a fermented starter culture. Salguero primarily uses fermented coconut milk yogurt or kefir, adding just enough to achieve the desired consistency. As an alternative, he suggests rejuvelac made from alfalfa. This starter introduces a robust community of beneficial lactic acid bacteria (LAB) and other microorganisms. These microbes are the architects of flavor and texture in cheesemaking, initiating the acidification process, breaking down sugars into lactic acid, and contributing a characteristic tang and depth. This step is analogous to the addition of starter cultures and rennet in traditional dairy cheesemaking, where enzymes begin the coagulation and flavor development process.

5. Initial Fermentation (24 Hours at 25°C/77°F):
The newly formed almond paste, now inoculated with its microbial allies, undergoes its first significant fermentation period. This phase, lasting 24 hours at a controlled temperature of approximately 25°C (77°F), is where the magic truly begins. The LAB proliferate, actively consuming sugars and producing lactic acid, which lowers the pH of the mixture. This acidification is vital for several reasons: it preserves the cheese, inhibits the growth of undesirable pathogens, and initiates the complex enzymatic reactions that develop the cheese’s characteristic flavor and aroma compounds. This stage is crucial for building the foundational "cheesy" notes.

6. Forming into Desired Shape:
Once the initial fermentation is complete, the almond mixture is ready to be formed into its final shape. This step allows for customization, whether creating small rounds, logs, or blocks, mirroring the diverse forms of traditional dairy cheeses. The shape also influences subsequent drying and aging processes, affecting how moisture is retained and how the rind develops.

7. Initial Dehydration (Approx. 4 Days at 20°C/68°F):
The formed cheese then undergoes a controlled dehydration process, lasting about four days at a low temperature of approximately 20°C (68°F). The primary objective here is to form a dry crust on the exterior, making the cheese easier to handle and providing a protective barrier. Crucially, the interior of the cheese retains moisture, allowing the fermentation process to continue slowly within. This balance between external drying and internal moisture is essential for the continued development of flavor and texture, mimicking the initial drying stages of many bloomy-rind or semi-hard dairy cheeses.

8. Submerging in Seawater or Brine (3 Days, Multiple Dips):
This step is a direct homage to ancient cheesemaking traditions. Beginning on the fourth day of dehydration, and continuing for an additional three days, the cheese is submerged in seawater or a prepared brine three times daily. This brining process is fundamental for several reasons:

• Salting: Salt acts as a natural preservative, drawing out excess moisture and inhibiting the growth of spoilage organisms.
• Flavor Enhancement: Salt amplifies the existing flavors and contributes to the overall savory profile.
• Rind Formation: The brine helps to firm up the exterior, contributing to the development of a distinct rind.
• Microbial Control: While beneficial microbes are desired internally, salt helps to control surface flora and create an environment conducive to desirable molds (if making a blue cheese, for example).
• If mixing a brine, Salguero recommends a 5% solution, which translates to 50 grams of salt per liter of water – a standard concentration in traditional cheesemaking.

9. Secondary Dehydration/Drying (Approx. 5 More Days at 10°C/50°F):
After the salting regimen, the cheese undergoes a further period of dehydration, lasting about five more days, but at a significantly cooler temperature of approximately 10°C (50°F). This lower temperature slows down enzymatic activity while continuing to gently reduce moisture content. This extended drying phase is crucial for developing a firmer texture and preparing the cheese for long-term aging. For those without a specialized dehydrator capable of such low temperatures, a refrigerator can serve as an effective alternative, albeit with potentially slower drying times.

10. Aging (3-6 Months at Cool Ambient Temperatures):
The final, and perhaps most transformative, stage is the aging process. The cheese is aged for a minimum of 3 to 6 months at cool ambient temperatures. This prolonged period is where the complex flavors truly mature and deepen. Enzymes continue to break down proteins and fats, creating a myriad of aromatic compounds that contribute to the cheese’s characteristic pungency, nuttiness, and umami. The texture also continues to evolve, becoming firmer, more crumbly, or creamier depending on moisture loss and enzymatic activity. This long aging period is what distinguishes Salguero’s creation from simpler, fresh vegan cheeses, aligning it with the artisanal quality of aged dairy cheeses like Parmesan or Gouda.

Blue Cheese Variation:
Adding another layer of sophistication, Salguero notes that it is possible to transform this aged almond cheese into a blue cheese. This is achieved by using a pin to carefully insert blue cheese molds (such as Penicillium roqueforti) into the interior of the cheese after the initial dehydration phase. This demonstrates the robustness and versatility of his base recipe, opening doors for further experimentation.

The Science Behind the Savory: Supporting Data

Salguero’s methodology is a brilliant fusion of traditional wisdom and modern understanding of food science. The complexity and depth of his vegan cheese are not accidental but rather the result of a deliberate application of principles fundamental to fermented foods.

Fermentation: The Ancient Art, Modern Science

Fermentation, at its core, is a biotechnological process where microorganisms convert organic compounds into simpler substances. In cheesemaking, whether dairy or plant-based, lactic acid bacteria are paramount. They metabolize sugars, primarily converting them into lactic acid. This acid lowers the pH, which is crucial for:

• Preservation: Acidic environments inhibit the growth of spoilage bacteria and pathogens.
• Flavor Development: Lactic acid itself contributes a tangy flavor, and the metabolic byproducts of various LAB strains create a spectrum of aromatic compounds (e.g., diacetyl for buttery notes, acetoin for a nutty aroma).
• Texture Modification: The acidic environment helps to denature proteins, contributing to the cheese’s structure and eventual texture.

In Salguero’s process, the sprouting of almonds further enhances this biochemical dance. Sprouting activates endogenous enzymes (like amylases and proteases) within the almonds, which pre-digest complex carbohydrates and proteins into simpler sugars and amino acids. These simpler molecules are then more readily available for the starter cultures, leading to more efficient fermentation and a broader array of flavor precursors.

Nutritional Enhancements

Beyond flavor, the fermentation and sprouting processes significantly boost the nutritional profile of the almond cheese. Sprouting increases levels of vitamins (especially B vitamins and vitamin C), antioxidants, and makes minerals like zinc and iron more bioavailable by reducing phytic acid. The probiotics introduced by the coconut kefir or rejuvelac contribute to gut health, making the cheese not just a culinary delight but also a functional food. Almonds themselves are a powerhouse of healthy fats, protein, fiber, vitamin E, and magnesium, offering a nutrient-dense base.

Sensory Science of "Cheesiness"

The elusive "cheesiness" is a complex interplay of taste, aroma, and texture. Salguero’s method meticulously addresses each of these:

• Umami: The breakdown of proteins into amino acids (especially glutamates) during fermentation and aging is a primary source of umami.
• Tang: Lactic acid provides the characteristic sour notes.
• Aroma: Volatile organic compounds produced by microbes create the pungent, nutty, and savory aromas.
• Texture: The combination of protein coagulation (aided by acidification), controlled dehydration, and enzymatic breakdown during aging creates the firm, yet yielding, and sometimes crumbly or creamy texture. The oil content of almonds contributes to a rich mouthfeel that mimics the fat content in dairy cheese.

Parallels to Traditional Dairy Cheesemaking

What makes Salguero’s method particularly compelling is its deep resonance with established dairy cheesemaking traditions. Each step has a direct analogue:

• Soaking & Sprouting: Similar to pre-treatment of milk (e.g., pasteurization, homogenization) to prepare it for coagulation, though with a different biological objective.
• Starter Culture: Directly parallels the inoculation of milk with specific bacterial cultures.
• Initial Fermentation: The equivalent of "ripening" the milk and the initial curd formation phase.
• Forming & Pressing: Standard practice for shaping dairy cheese and expelling whey.
• Dehydration & Brining: Mirror the drying and salting stages crucial for rind development, preservation, and flavor in cheeses like cheddar, Gouda, or Parmesan.
• Aging: The most direct parallel, where time and controlled conditions allow enzymes to transform simple curds into complex, flavorful aged cheeses.

By adopting these time-tested techniques, Salguero is not simply creating a "nut spread" but crafting a genuine fermented food product with the integrity and complexity of artisanal cheese.
