Nico Salguero’s vegan cheese is not merely a substitute; it is a meticulously crafted artisan product that leverages the power of fermentation, sprouting, and controlled aging to achieve its complex character. It represents a significant leap forward from many commercial vegan cheeses, which often rely on starches, oils, and artificial flavorings to mimic dairy, frequently falling short in terms of taste, texture, and nutritional value. Salguero’s method, rooted in traditional cheesemaking principles, promises a truly gourmet experience for vegans, flexitarians, and dairy enthusiasts alike.

Chronology: The Craft of Nico Salguero’s Almond "Cheese"

The journey from raw almonds to a deeply aged, complex vegan cheese is a testament to patience, precision, and an understanding of microbiological processes. Nico Salguero’s method is a multi-stage, carefully orchestrated sequence designed to unlock the full potential of its plant-based ingredients. Below is a detailed chronological breakdown of his innovative process, providing insight into the "why" behind each crucial step.

Stage 1: Preparation – Activating the Almonds

The foundation of this exceptional cheese begins with the humble almond, transformed through a series of preparatory steps that enhance its nutritional profile, texture, and readiness for fermentation.

• Soak Almonds (Approx. 24 hours): This initial step is vital. Soaking activates enzymes within the almonds, initiating the germination process. It helps to break down phytic acid, an anti-nutrient that can inhibit mineral absorption, thereby increasing the bioavailability of the almond’s inherent nutrients. Furthermore, soaking softens the almonds significantly, making them easier to process and contributing to a smoother final texture. The water should be changed periodically, especially in warmer climates, to prevent undesirable microbial growth.
• Remove Skins: Once sufficiently softened by soaking, the almond skins are carefully removed. This step is crucial for achieving the creamy, uniform texture characteristic of fine cheese. Almond skins, while nutritious, can impart a slightly bitter taste and a grainy texture, which would detract from the desired smooth mouthfeel of the finished product. The removal of skins also allows for better interaction between the almond flesh and the fermenting cultures.
• Sprout the Soaked Almonds (Approx. 2 days): This is perhaps one of the most distinctive and impactful steps in Salguero’s process. Sprouting takes the activated almonds to the next level, further increasing enzyme activity and transforming complex starches and proteins into simpler, more digestible forms. During sprouting, amino acid profiles can change, and new flavor precursors develop, contributing significantly to the depth and complexity of the final cheese. The process requires careful monitoring: almonds must be kept moist but consistently drained to ensure adequate air circulation, preventing mold and promoting healthy germination. Regular rinsing (e.g., every 8-12 hours) is essential to wash away metabolic byproducts and maintain hydration.

Stage 2: Fermentation – Cultivating Flavor

With the almonds optimally prepared, the focus shifts to introducing beneficial microorganisms that will perform the magical alchemy of fermentation.

• Grind Almonds with Fermented Coconut Milk Yogurt or Kefir: The sprouted, skinless almonds are then ground into a thick, cohesive paste. This is not done with plain water, but with a carefully selected live culture: fermented coconut milk yogurt or kefir. These cultures introduce a diverse array of lactic acid bacteria (LAB) and yeasts, which are the primary agents of fermentation. The LAB consume sugars in the almonds, producing lactic acid, which contributes to the characteristic tang and preserves the cheese. The choice of coconut milk culture is critical; it provides a robust starter culture that also imparts subtle complementary notes. As an alternative, Salguero suggests rejuvelac of alfalfa, a potent lacto-fermented liquid known for its high enzyme content and vibrant microbial diversity, which can lend a unique character to the cheese. The goal is a smooth, thick paste, just wet enough for efficient grinding and subsequent fermentation.
• Ferment for 24 hours (approx. 25°C/77°F): The almond paste, now inoculated with beneficial cultures, undergoes its primary fermentation. This stage is where the foundational "cheesy" flavors begin to develop. At 25°C (77°F), the lactic acid bacteria are highly active, metabolizing sugars, producing organic acids, and initiating the breakdown of proteins and fats. This not only creates the characteristic tangy flavor but also improves digestibility and develops a more complex aroma profile. The consistency of the paste will subtly change, becoming slightly more acidic and perhaps showing minor gas production.

Stage 3: Shaping and Initial Dehydration – Forming the Foundation

Once the initial fermentation is complete, the cheese is prepared for its structural and textural development.

• Form into Desired Shape: The fermented almond paste is then carefully molded into the desired cheese shape. This could be a traditional wheel, a log, or any form that allows for even aging and handling. The density of the compaction at this stage can influence the final texture of the cheese, with firmer packing leading to a denser final product.
• Dehydrate (First Stage – Approx. 4 days at 20°C/68°F): This initial dehydration is a crucial step in traditional cheesemaking, and Salguero applies it expertly here. The aim is to create a dry, firm crust on the exterior of the cheese while allowing the interior to retain significant moisture. This crust provides structural integrity, making the cheese easier to handle for subsequent steps like brining, and acts as a protective barrier. Crucially, by maintaining moisture in the interior, the fermentation process can continue slowly, allowing for a gradual deepening of flavors and textural changes within the protected core. The low temperature ensures slow, controlled drying without cooking the delicate ferments.

Stage 4: Salting and Secondary Dehydration – Preservation and Flavor Enhancement

Salting is a cornerstone of cheesemaking, playing multiple roles in flavor, preservation, and texture.

• Submerge Cheese in Seawater or Brine (Beginning on Day 4 of dehydration, for 3 days, 3 times daily): This step directly mirrors the salting techniques used in many aged dairy cheeses, highlighting Salguero’s deep understanding of traditional methods. Salting is multifaceted: it imparts flavor, acts as a natural preservative by inhibiting spoilage organisms, and draws out additional moisture, further firming the cheese. The use of seawater, if available and clean, can introduce unique trace minerals and a more complex salinity profile. Otherwise, a 5% brine (50 grams of salt per liter of water) is recommended. The repeated submersion ensures even salt distribution throughout the exterior and gradually into the interior, contributing to a balanced flavor and texture.
• After Salting, Dehydrate About 5 More Days (Approx. 10°C/50°F): Following the brining, the cheese undergoes a second, longer dehydration phase, this time at an even cooler temperature. This further reduces moisture content, concentrating flavors and firming the cheese significantly. The lower temperature slows down microbial activity, preparing the cheese for the extended aging process. If a dehydrator capable of such low temperatures isn’t available, a refrigerator can serve as an adequate alternative, albeit with potentially longer drying times due to higher humidity.

Stage 5: Aging – The Culmination of Complexity

The final, and perhaps most transformative, stage is the prolonged aging period.

• Age Cheese for 3-6 Months (Cool Ambient Temperatures): This extended aging period is where the "cheese" truly develops its character, complexity, and depth of flavor. During these months, enzymatic processes continue to break down proteins and fats, creating a cascade of new aromatic and flavor compounds. The texture evolves from firm to potentially crumbly or creamy, depending on moisture loss and specific microbial activity. The cool ambient temperatures slow these processes down, allowing for a gradual, nuanced development that cannot be rushed. Just like fine wine or traditional dairy cheese, time is an indispensable ingredient, allowing the subtle notes to emerge and meld into a harmonious symphony of taste.

Blue Cheese Variation: Introducing a Fungal Element

For those seeking an even bolder flavor profile, Salguero notes that this almond cheese can be adapted into a blue cheese. After the initial dehydration (Stage 3), a clean pin can be used to carefully insert blue cheese molds (e.g., Penicillium roqueforti spores) into the interior of the cheese. This introduces a new layer of fungal fermentation, leading to the distinctive pungent aroma, sharp flavor, and characteristic blue veins associated with blue cheeses.

Supporting Data: The Science and Art of Plant-Based Fermentation

Nico Salguero’s creation is more than just a recipe; it’s a masterclass in applying sophisticated food science and traditional culinary artistry to plant-based ingredients. Understanding the underlying principles illuminates why this cheese is so remarkable.

The Global Rise of Vegan Cheese

The demand for high-quality vegan cheese has exploded in recent years. Driven by increasing awareness of animal welfare, environmental concerns, and perceived health benefits of plant-based diets, consumers are actively seeking alternatives to dairy. However, the market has often been criticized for producing products that fail to deliver on taste and texture, leaving a significant gap for genuinely gourmet options. Salguero’s almond cheese directly addresses this void, demonstrating that plant-based alternatives can achieve true culinary excellence. Market analyses predict continued rapid growth in the vegan cheese sector, making innovations like Salguero’s highly pertinent.

Fermentation: An Ancient Art, Modern Science

Fermentation, the metabolic process by which microorganisms convert carbohydrates into alcohol or acids, has been used for millennia to preserve food and enhance flavor. In cheesemaking, whether dairy or plant-based, lactic acid bacteria are the primary agents. They consume sugars, producing lactic acid, which lowers the pH, inhibiting spoilage organisms and contributing to the characteristic tang. Beyond preservation, fermentation is a complex biochemical factory that creates a myriad of flavor compounds, including volatile fatty acids, aldehydes, ketones, and esters, all contributing to the "cheesy" aroma and taste. Salguero’s controlled fermentation steps precisely harness these microbial transformations.

Almonds as a Superior Base

While many vegan cheeses use cashews or soy, almonds offer unique advantages. Their relatively neutral flavor profile allows the complex notes developed during fermentation and aging to shine through. Nutritionally, almonds are rich in healthy monounsaturated fats, protein, fiber, vitamin E, and magnesium, contributing to both the creamy texture and nutritional value of the final product. The specific preparation—soaking, skinning, and especially sprouting—unlocks these nutrients and prepares the almond matrix for optimal enzymatic and microbial activity, leading to superior texture and flavor development.

The Magic of Sprouting

Sprouting is a key differentiator in Salguero’s process. It mimics nature’s way of "waking up" a seed. During sprouting, dormant enzymes within the almond become active, breaking down complex molecules like starches and proteins into simpler sugars and amino acids. This makes the almonds easier to digest and provides a readily available food source for the fermenting cultures. More importantly, sprouting can lead to the formation of new flavor compounds and an overall more "alive" and vibrant taste profile, which translates directly into the complexity of the aged cheese.

Cultures: Coconut Milk Kefir and Rejuvelac

The choice of starter culture is paramount. Coconut milk kefir or yogurt provides a robust and diverse community of lactic acid bacteria and yeasts. These cultures are well-adapted to fermenting plant-based substrates and contribute their own unique metabolic byproducts, influencing the final flavor. Rejuvelac, derived from sprouted grains like alfalfa, is renowned for its enzymatic activity and a distinct sour, slightly effervescent quality, offering a different flavor trajectory for the cheese. Both options provide the necessary microbial horsepower to drive the fermentation process.

Controlled Environment: Temperature, Humidity, and Time

Just like traditional cheesemaking, the success of Salguero’s almond cheese hinges on meticulous control of environmental factors during dehydration and aging. Temperature dictates the speed of enzymatic and microbial activity, while humidity influences moisture loss and rind development. An uncontrolled environment can lead to spoilage, off-flavors, or a failure to achieve the desired texture. The precise temperatures and durations specified by Salguero ensure that the beneficial microorganisms thrive, and the cheese ages gracefully, developing its full potential over several months.

Flavor Development and Umami

The ultimate goal of this intricate process is the development of rich, savory, and complex flavors – what many refer to as "umami." Through fermentation and aging, proteins are broken down into amino acids, particularly glutamates, which are responsible for the umami taste. Fats are also hydrolyzed into fatty acids, contributing to depth and richness. The interplay of lactic acid, volatile compounds, and the gradual breakdown of the almond matrix creates a profile that genuinely evokes the satisfying, multifaceted experience of aged dairy cheese.
