Generously, Salguero shared the intricate details of his process, a testament to his dedication and innovative spirit, providing a roadmap for an exciting new frontier in plant-based cuisine.

The Artisan Behind the Innovation: Nico Salguero

Nico Salguero, a local resident and participant in the intensive fermentation workshop, embodies the growing global movement towards sustainable and plant-forward eating. His journey into crafting such an exceptional vegan cheese was born from a passion for fermentation and a desire to create plant-based alternatives that do not compromise on flavor or authenticity. While the specifics of his background are modest, his culinary instincts and meticulous approach to traditional techniques are anything but. He has spent considerable time experimenting, refining, and understanding the subtle interplay of microorganisms, temperature, and time – elements critical to both dairy and plant-based cheesemaking. His creation is not merely a substitute but a stand-alone culinary achievement, bridging the gap between ancient fermentation practices and modern dietary demands. The workshop, focused on unlocking the transformative power of microbes in food, provided the perfect crucible for Salguero to share his breakthrough, demonstrating how traditional wisdom can be applied to innovative plant-based solutions.

The Alchemy of Flavor: A Chronology of Creation

Salguero’s method is a sophisticated, multi-stage process that draws heavily on principles found in traditional dairy cheesemaking, adapted ingeniously for plant-based ingredients. The core components are almonds and a potent fermented liquid, demonstrating a deep understanding of how to build complex flavors and textures from simple, natural sources.

Step 1: Initiating Vitality – Soaking Almonds (24 Hours)

The journey begins with raw almonds, which are submerged in water for approximately 24 hours. This crucial initial step serves multiple purposes. Hydration softens the almonds, making them pliable for subsequent processing and facilitating the removal of their skins. More importantly, soaking begins to awaken the almond’s dormant life force, initiating enzymatic activity that breaks down anti-nutrients like phytic acid, thereby enhancing digestibility and nutrient bioavailability. This practice is a cornerstone of traditional food preparation across many cultures, maximizing the nutritional potential of nuts and grains.

Step 2: Refining Texture – Removing Skins

Following the soaking period, the almond skins are meticulously removed. This step is not merely for aesthetic appeal; it significantly contributes to the final texture and mouthfeel of the cheese. Almond skins can impart a slightly bitter taste and a grainy texture, which would detract from the creamy, smooth consistency desired in a fine cheese. This manual process underscores the artisanal nature of Salguero’s approach, prioritizing quality and sensory experience above all else.

Step 3: Unleashing Potency – Sprouting Almonds (Approx. 2 Days)

Perhaps the most distinctive and impactful step in Salguero’s process is the sprouting of the soaked almonds. For approximately two days, the almonds are allowed to sprout, a period during which they are periodically rinsed to maintain moisture while ensuring adequate air exposure. Sprouting is a biochemical marvel:

• Enzymatic Activation: It dramatically increases the activity of beneficial enzymes, further breaking down complex starches and proteins into simpler, more digestible forms.
• Nutrient Boost: The sprouting process significantly boosts the content of vitamins (particularly B vitamins) and antioxidants, transforming the almond into a living, nutrient-dense ingredient.
• Flavor Development: Sprouting mellows the almond’s inherent bitterness, introducing subtle sweet and fresh notes that contribute significantly to the cheese’s nuanced flavor profile.
• Textural Transformation: The internal structure of the almond changes, becoming softer and more amenable to forming a cohesive, cheesy matrix.

This stage is critical for creating a foundational ingredient that is not only highly nutritious but also primed for the subsequent fermentation processes, offering a unique complexity not found in unsprouted nut cheeses.

Step 4: Infusing Culture – Grinding with Fermented Starter

The sprouted almonds are then ground into a thick paste. The choice of grinding medium is pivotal: fermented coconut milk yogurt or kefir. These fermented liquids introduce a rich consortium of beneficial microorganisms, primarily Lactic Acid Bacteria (LAB), which are the workhorses of cheesemaking. LAB are responsible for:

• Flavor Complexity: They metabolize sugars, producing lactic acid, which imparts the characteristic tang and depth of flavor found in traditional cheeses. They also contribute to the development of a vast array of volatile compounds that create the "cheesy" aroma.
• Texture Modification: The acids and enzymes produced by these cultures help to break down the almond proteins, contributing to the desired creamy yet firm texture.
• Preservation: The acidic environment created by LAB inhibits the growth of spoilage organisms, acting as a natural preservative.

As an alternative, Salguero suggests rejuvelac of alfalfa. Rejuvelac, a fermented liquid typically made from grains or legumes, is another excellent source of probiotics and enzymes, offering a slightly different, yet equally effective, microbial profile for fermentation. The quantity of fermented liquid is precisely enough to achieve a "thick paste," ensuring the starter cultures are concentrated and active within the almond base.

Step 5: The First Fermentation – Flavor Foundation (24 Hours)

The newly formed almond paste undergoes its primary fermentation for 24 hours at approximately 25°C (77°F). This temperature is carefully selected as it represents the optimal range for the Lactic Acid Bacteria to thrive and rapidly convert sugars into lactic acid. During this critical period, the initial "cheese" flavor begins to develop, the mixture acidifies, and the texture starts to firm up. This stage is where the raw ingredients truly begin their transformation into something recognizable as cheese, laying the groundwork for the more complex flavors that will emerge during aging.

Step 6: Crafting Identity – Forming Desired Shape

Once the initial fermentation is complete, the cheese paste is carefully formed into the desired shape. This step, while seemingly simple, is crucial for both aesthetic presentation and practical handling during the subsequent dehydration and brining stages. The shape influences how the cheese will age, how moisture will evaporate, and how the rind will develop.

Step 7: Building the Crust – Initial Dehydration (Approx. 4 Days)

The shaped cheese then enters its first dehydration phase, lasting about four days at a low temperature of approximately 20°C (68°F). The objective here is two-fold:

• Rind Formation: To create a dry, protective crust on the exterior, which makes the cheese easier to handle and provides a barrier against undesirable external molds.
• Internal Moisture Retention: Crucially, the low temperature ensures that while the exterior dries, the interior of the cheese retains sufficient moisture. This allows the beneficial fermentation processes initiated by the LAB to continue slowly within the core of the cheese, further developing flavor and texture without drying out prematurely.

Step 8: The Salting Ritual – Brining (3 Days)

Following the initial dehydration, the cheese undergoes a brining process, a technique directly borrowed from traditional dairy cheesemaking. For three consecutive days, starting on the fourth day of dehydration, the cheese is submerged in seawater or a prepared brine three times daily. This practice is essential for several reasons:

• Flavor Enhancement: Salt is a fundamental flavor enhancer, bringing out the nuances developed during fermentation.
• Moisture Regulation: Brining helps to draw out excess moisture, contributing to a firmer texture.
• Preservation: Salt acts as a natural antimicrobial agent, inhibiting the growth of spoilage bacteria while allowing beneficial cultures to thrive.
• Rind Development: The salt interacts with the proteins on the cheese surface, contributing to the formation of a stable, protective rind.

If preparing a brine, Salguero recommends a 5% solution, which translates to 50 grams of salt per liter of water – a standard concentration for many aged cheeses. This step is a clear indicator of Salguero’s reverence for classic cheesemaking techniques and his understanding of their applicability to plant-based ingredients.

Step 9: Slow Drying – Secondary Dehydration (Approx. 5 Days)

After the intensive brining process, the cheese undergoes a second phase of dehydration for approximately five more days, this time at an even cooler temperature, around 10°C (50°F). This cooler temperature facilitates a slower, more controlled drying, which is vital for the long-term aging process. If a specialized dehydrator capable of these low temperatures is unavailable, a refrigerator can serve as an effective alternative, as its consistent cool, dry environment mimics the conditions needed for this stage. This secondary drying further hardens the rind and prepares the internal structure for the extended aging period.

Step 10: The Grand Finale – Aging (3-6 Months)

The culmination of Salguero’s meticulous process is the aging phase, which lasts between three to six months at cool ambient temperatures. This extended period is where the true magic of cheesemaking unfolds:

• Enzyme Activity: Enzymes, both from the almonds and the microbial cultures, continue to break down complex proteins and fats into simpler compounds, creating a profound depth of flavor (umami) and aroma.
• Flavor Development: Volatile compounds, characteristic of aged cheeses, develop, contributing to a complex bouquet of nutty, earthy, and tangy notes.
• Texture Transformation: The cheese gradually loses more moisture, firming up and developing a more crumbly or sliceable texture, depending on the desired outcome.
• Rind Maturation: The rind continues to mature, contributing to the cheese’s overall character and protecting its interior.

This long aging period is what truly distinguishes Salguero’s creation from most quick-set vegan cheeses, allowing for the development of a richness and complexity that can only be achieved through time and patience.

The Blue Cheese Variation

Adding another layer of innovation, Salguero notes that his cheese can also be transformed into a blue cheese. This is achieved by using a pin to insert blue cheese molds into the interior of the cheese after the initial dehydration phase. This technique mirrors the traditional method for inoculating dairy blue cheeses, demonstrating the versatility and adaptability of his base recipe.

The Science of Plant-Based Fermentation and Its Global Implications

Salguero’s artisanal vegan cheese is more than just a recipe; it’s a masterclass in the science of fermentation and a powerful statement on the future of food. The process leverages the natural transformative power of microorganisms to convert simple plant ingredients into complex, nutrient-rich foods. Lactic acid fermentation, central to Salguero’s method, is a cornerstone of global food preservation and flavor development. By using specific bacterial cultures, he orchestrates a symphony of biochemical reactions that break down carbohydrates, produce acids, and synthesize new aromatic compounds, mimicking the intricate processes found in traditional dairy cheesemaking.

The choice of sprouted almonds is particularly astute. Sprouting not only enhances digestibility and nutrient availability but also pre-conditions the substrate for fermentation, providing a more accessible food source for the microbes and contributing unique flavor precursors. This thoughtful combination of ancient wisdom (sprouting, fermentation, aging) with plant-based ingredients represents a significant leap forward in the quest for truly satisfying and sustainable food alternatives.

Expert Perspectives and Industry Impact
