During a teaching workshop held in the vibrant Argentine capital, an unexpected encounter with an extraordinary vegan cheese has captivated the attention of fermentation enthusiasts and food critics alike. This wasn’t merely a passable substitute; it was hailed as "the best, cheesiest vegan cheese" the workshop instructor had ever tasted, a testament to its remarkable flavor and texture complexity.

The mastermind behind this revelation is Nico Salguero, a student attending the workshop, whose generosity in sharing his intricate process has opened a window into the future of plant-based gastronomy. His creation, an aged almond-based cheese, defies conventional expectations of vegan dairy, presenting a depth of umami, tang, and firm yet creamy texture often reserved for traditional animal-milk cheeses. This article delves into Salguero’s meticulous methodology, exploring the scientific principles, culinary artistry, and broader implications of his groundbreaking work.

The Crafting of a Masterpiece: Nico Salguero’s Vegan Cheese Process

Nico Salguero’s recipe is not for the faint of heart, requiring patience, precision, and a deep understanding of fermentation. It is a multi-stage process that meticulously transforms simple almonds into a gourmet aged cheese, mirroring many of the time-honored techniques employed in traditional dairy cheesemaking.

Step 1: The Foundation – Soaking and Sprouting Almonds

The journey begins with the careful preparation of the primary ingredient: almonds. Salguero instructs to soak almonds in water for approximately 24 hours. This initial soaking is more than just rehydration; it’s a crucial step that initiates a cascade of biochemical changes within the nut. Soaking helps to neutralize enzyme inhibitors present in raw nuts, making them easier to digest and increasing the bioavailability of their nutrients. It also softens the almonds, preparing them for the next critical phase.

Following the soak, the skins are meticulously removed. This step is vital for achieving a smooth, creamy texture in the final product, preventing any grittiness or undesirable color variations that the skins might impart. The attention to detail here underscores the artisanal nature of the process.

The softened, blanched almonds then undergo a transformation through sprouting, lasting about two days. This is arguably one of the most innovative aspects of Salguero’s method. During sprouting, the almonds are kept moist but well-drained, ensuring access to air. This controlled environment encourages germination, where the almond begins to awaken, activating enzymes that convert complex starches into simpler sugars, and proteins into more digestible amino acids. This process not only enhances the nutritional profile but also develops more complex flavor precursors, contributing to the "cheesy" notes that will emerge later. The subtle sweetness and nutty depth of sprouted almonds provide an ideal canvas for fermentation.

Step 2: Preparation – Grinding with Fermented Cultures

Once sprouted, the almonds are ready for their transformation into a paste. Salguero instructs to grind the almonds with fermented coconut milk yogurt or kefir, using just enough liquid to achieve a thick, homogenous paste. This step introduces the vital microbial cultures that will drive the fermentation process. Coconut milk yogurt or kefir, rich in beneficial lactic acid bacteria (LAB), serves as the starter culture. These probiotics are responsible for producing lactic acid, which contributes to the characteristic tang and helps preserve the cheese. As an intriguing alternative, Salguero suggests rejuvelac of alfalfa, a fermented liquid derived from sprouted grains or legumes, known for its probiotic content and slightly effervescent, tangy flavor. The choice of starter significantly influences the final flavor profile and microbial ecosystem of the cheese.

Step 3: Initial Fermentation – Cultivating Complexity

With the paste formed and inoculated, the mixture enters its initial fermentation phase. It is allowed to ferment for 24 hours at approximately 25°C/77°F. This controlled temperature provides an optimal environment for the lactic acid bacteria to thrive. During this period, the LAB metabolize the sugars present in the almonds (which were further broken down during sprouting) and the starter culture, producing lactic acid, acetic acid, and various volatile compounds. This fermentation is crucial for developing the cheese’s characteristic sourness, depth of flavor, and helping to set its initial texture. It’s akin to the culturing phase in traditional dairy cheesemaking, where milk is inoculated and allowed to acidify.

Step 4: Shaping and Initial Dehydration – Forming the Future

After the initial fermentation, the cheese paste is ready to be formed into the desired shape. This step is both aesthetic and functional, preparing the cheese for handling and subsequent aging. The formed cheese then undergoes an initial dehydration for about four days at a low temperature, approximately 20°C/68°F. The primary objective here is to create a dry crust on the exterior, which facilitates easier handling and protects the interior. Crucially, while the outside dries, the interior retains significant moisture, allowing the fermentation process to continue slowly within the cheese. This slow, internal fermentation contributes to further flavor development and enzymatic activity, which are key to achieving a truly aged character.

Step 5: The Brining Ritual – Salting for Flavor and Preservation

One of the most revealing aspects of Salguero’s method is his sophisticated approach to salting, drawing direct parallels to traditional cheesemaking. Beginning on the fourth day of dehydration and continuing for three additional days, the cheese is submerged in seawater or a 5% brine three times each day. This precisely mimics the brining techniques used for many aged dairy cheeses. Salting is not merely for flavor; it plays a critical role in moisture regulation, drawing out excess water and inhibiting the growth of unwanted microorganisms, thus acting as a preservative. It also contributes significantly to the development of the cheese’s final flavor profile, enhancing umami notes and providing balance. A 5% brine, or 50 grams of salt per liter of water, ensures an effective and controlled salting process.

Step 6: Secondary Dehydration – Refining the Texture

Following the intensive brining period, the cheese undergoes a secondary dehydration for about five more days at a cooler temperature, approximately 10°C/50°F. This extended drying phase is crucial for further reducing moisture content, concentrating flavors, and firming up the cheese’s texture. The lower temperature slows down enzymatic activity and microbial growth, allowing for a more controlled maturation. For those without a specialized dehydrator capable of such low temperatures, Salguero advises that a standard refrigerator can serve as a viable alternative, albeit with potentially slower moisture loss.

Step 7: The Grand Finale – Long-Term Aging

The culmination of Salguero’s process is the long-term aging of the cheese for 3-6 months at cool ambient temperatures. This extended maturation period is where the magic truly happens. Similar to aged dairy cheeses like Parmesan or Gouda, time allows for complex enzymatic reactions to break down proteins and fats, generating a myriad of aromatic compounds. The flavors deepen, becoming more nuanced, savory, and "cheesy." The texture transforms, becoming firmer, denser, and developing the characteristic richness associated with aged products. This aging process is the ultimate differentiator, elevating the almond paste from a simple fermented spread to a truly sophisticated, gourmet cheese.

An Optional Twist: Crafting Blue Vegan Cheese

Adding another layer of sophistication, Salguero notes that it is possible to transform this aged almond cheese into a blue cheese. This involves using a pin to insert blue cheese molds into the interior of the cheese after the initial dehydration. This technique, mirroring the creation of traditional blue cheeses, introduces specific Penicillium strains that develop characteristic blue veins and pungent flavors during the subsequent aging process.

The Science and Art Behind Vegan Cheesemaking

Nico Salguero’s recipe is not just a set of instructions; it’s a masterclass in applying scientific principles to culinary art. It embodies the cutting edge of plant-based food innovation, leveraging fermentation, controlled dehydration, and long-term aging to achieve results previously thought impossible for vegan products.

The Rise of Plant-Based Alternatives

The demand for plant-based foods has surged globally, driven by a confluence of factors: increasing awareness of animal welfare, environmental concerns related to industrial agriculture, and growing interest in health and wellness. Within this movement, vegan cheese has long been a challenging frontier. Early iterations often fell short in terms of flavor, texture, and meltability. However, recent years have seen remarkable progress, with innovators like Salguero pushing the boundaries of what’s achievable. This shift reflects a broader trend of moving beyond simple "substitutes" to creating unique, high-quality culinary experiences that stand on their own merit.

Fermentation: An Ancient Art, Modern Science

At the heart of Salguero’s method is fermentation, an ancient biotechnological process that has been central to food preservation and flavor development for millennia. In this context, lactic acid bacteria (LAB) play the starring role. These microorganisms consume carbohydrates and produce lactic acid, which lowers the pH, inhibiting spoilage organisms, and contributing a characteristic tangy flavor. Beyond lactic acid, LAB produce a vast array of enzymes and volatile compounds that contribute to the complex aroma, taste, and texture of fermented foods. In the case of this almond cheese, fermentation breaks down the nut’s components, making them more digestible and unlocking a spectrum of savory, umami-rich, and acidic notes that are foundational to "cheesy" flavors. The sprouting of almonds further primes them for fermentation by activating enzymes that break down complex molecules into simpler sugars, making them more accessible to the fermenting cultures.

Almonds as a Premium Base

The choice of almonds as the primary base is strategic. Almonds possess a favorable fat-to-protein ratio, which is crucial for achieving a rich texture and mouthfeel reminiscent of dairy cheese. Their relatively neutral flavor profile also allows the complex notes developed through sprouting, fermentation, and aging to shine through. While other nuts like cashews are popular in vegan cheesemaking, almonds offer a distinct textural advantage and a subtle sweetness that complements the fermentation process. The fat content contributes to creaminess, while the protein structure helps in forming a cohesive, sliceable product.

Beyond Imitation: Crafting Unique Culinary Experiences

What sets Salguero’s creation apart is its ability to transcend mere imitation. While it evokes the sensory experience of traditional aged cheese, it simultaneously establishes itself as a distinct culinary entity. The combination of sprouted almonds, specific cultures, and meticulous aging creates a flavor profile that is uniquely its own—a sophisticated interplay of nutty, tangy, earthy, and umami notes. This approach represents a significant leap forward, moving beyond the goal of simply replicating dairy to creating novel and compelling gastronomic experiences within the plant-based paradigm.
