The meticulous process, generously shared by Salguero, outlines a complex yet accessible methodology that promises to inspire both home fermenters and commercial producers alike.

The Genesis of a Culinary Revelation

The journey to this exceptional vegan cheese begins not in a factory, but through a thoughtful, artisanal approach that prioritizes natural processes and patient maturation. Nico Salguero’s method is a testament to the power of fermentation, sprouting, and careful environmental control in transforming simple ingredients into a complex culinary masterpiece. The core ingredient, almonds, undergoes a series of transformations designed to enhance flavour, texture, and nutritional profile, ultimately mimicking the depth and character typically associated with aged dairy cheeses.

The meticulous steps involved highlight a deep understanding of microbial activity, enzymatic reactions, and moisture management – principles fundamental to traditional cheesemaking. By adapting these age-old techniques to plant-based components, Salguero has not merely created an alternative but forged a new standard for vegan cheese, distinguished by its authentic "cheesy" essence and satisfying mouthfeel.

Unveiling the Craft: A Step-by-Step Fermentation Masterpiece

The creation of Nico Salguero’s acclaimed vegan cheese is a multi-day, multi-stage process demanding patience and precision. Each step plays a crucial role in developing the unique flavour, texture, and stability of the final product.

The Preparation: Activating the Almonds

The initial stages focus on preparing the almonds to unlock their full potential, both nutritionally and culinarily.

1. Soak Almonds (Approximately 24 hours):
   The process begins with soaking raw almonds in water for approximately 24 hours. This crucial first step serves multiple purposes. Soaking softens the almonds, making them easier to process. More importantly, it initiates enzyme activity within the almond, beginning the breakdown of complex carbohydrates and proteins. This not only enhances digestibility but also sets the stage for flavour development by making nutrients more accessible to the beneficial microorganisms that will later drive fermentation.

2. Remove Skins:
   Following the soak, the almond skins are removed. This step is primarily for texture, ensuring a smoother, creamier final product free from the slight grittiness or bitterness that skins can impart. It also allows for more uniform sprouting and fermentation.

3. Sprout the Soaked Almonds (Approximately 2 days):
   This is a pivotal and innovative step, distinguishing Salguero’s method from many other vegan cheese recipes. The skinned almonds are then sprouted for about two days. During this period, they must be rinsed periodically to maintain moisture while ensuring adequate drainage and air exposure. Sprouting is a biochemical marvel: the almond, a dormant seed, awakens, activating enzymes that convert starches into simpler sugars, break down proteins into amino acids, and increase vitamin content. This transformation contributes significantly to the "cheesy" flavour profile by developing flavour precursors and reducing anti-nutrients like phytic acid, making the nutrients more bioavailable. The slight sweetness and complex notes emerging from sprouted almonds provide a superior base for fermentation.

The Fermentation: Cultivating Flavour and Texture

With the almonds optimally prepared, the focus shifts to introducing beneficial microbial cultures to transform the almond paste into a cheese-like substance.

1. Grind Almonds with Fermented Coconut Milk Yogurt or Kefir:
   The sprouted almonds are then ground into a thick paste. The key is to incorporate a live, active starter culture. Salguero recommends using fermented coconut milk yogurt or kefir, adding just enough to achieve the desired consistency. These cultures, typically rich in lactic acid bacteria (LAB), are responsible for the characteristic tangy flavours and textural changes associated with cheese. As an alternative, Salguero suggests using rejuvelac of alfalfa – a fermented liquid derived from sprouted grains or legumes – which provides a different spectrum of beneficial microbes and enzymes, potentially influencing the final flavour and complexity. The grinding process ensures intimate contact between the almond substrate and the microbial cultures, facilitating an even and robust fermentation.

2. Ferment for 24 hours at 25°C/77°F:
   The almond paste, now inoculated with starter cultures, undergoes its primary fermentation. Maintaining a consistent temperature of approximately 25°C (77°F) is crucial, as this temperature optimizes the activity of the lactic acid bacteria. During this 24-hour period, the bacteria consume the sugars present in the almonds, producing lactic acid, acetic acid, and other metabolic byproducts. This acidifies the paste, which acts as a natural preservative, inhibits undesirable microbes, and begins to develop the characteristic sour and complex notes associated with cheese. The texture also starts to firm up as proteins coagulate due to the changing pH.

3. Form into Desired Shape:
   After the initial fermentation, the cheese paste has developed enough structure and flavour to be shaped. This step allows for aesthetic presentation and prepares the cheese for subsequent drying and aging, where the surface area and form can influence rind development and moisture loss.

The Curing and Aging: Developing Depth and Character

The final stages are critical for transforming the fermented almond paste into a sophisticated aged cheese, focusing on moisture control, salting, and long-term maturation.

1. Dehydrate for About Four Days at a Low Temperature (Approximately 20°C/68°F):
   The formed cheese undergoes an initial dehydration phase. The objective here is two-fold: to create a dry crust or rind on the exterior, making the cheese easier to handle and providing a protective barrier, while crucially allowing the interior to retain sufficient moisture for continued enzymatic activity and fermentation. This low-temperature drying encourages the development of a natural rind, which is vital for the aging process, preventing excessive moisture loss and protecting the delicate interior. This controlled drying phase is fundamental to developing the cheese’s eventual texture and complexity.

2. Submerge Cheese in Seawater or Brine (Beginning on Day 4 of Dehydration, for 3 days):
   Starting on the fourth day of dehydration, and continuing for three additional days, the cheese is submerged in brine three times daily. This brining process is directly analogous to how many aged dairy cheeses are salted and is indispensable for flavour, preservation, and moisture regulation. If preparing a brine, a 5% solution (50 grams of salt per liter of water) is recommended. Salt plays a multifaceted role: it draws out excess moisture, inhibits spoilage organisms, enhances flavour, and influences the activity of enzymes and beneficial microbes, contributing to the development of the cheese’s characteristic texture and taste. The repeated submersion ensures even salt penetration.

3. After Salting, Dehydrate About 5 More Days at a Low Temperature (Approximately 10°C/50°F):
   Following the brining period, the cheese undergoes a secondary, longer dehydration phase at an even lower temperature, around 10°C (50°F). This slower, cooler drying further reduces moisture content, concentrating flavours and firming the cheese. If a specialized dehydrator capable of such low temperatures is unavailable, a refrigerator can serve as an effective alternative, as its consistent cool and relatively dry environment facilitates the gradual moisture reduction required. This step prepares the cheese for its long maturation.

4. Age Cheese for 3-6 Months at Cool Ambient Temperatures:
   The final and arguably most transformative stage is aging. For 3 to 6 months, the cheese is stored at cool ambient temperatures. During this extended period, complex enzymatic and microbial processes continue within the cheese. Proteins break down into amino acids, fats transform into fatty acids, and the interaction of various compounds creates a rich tapestry of nuanced flavours, including umami, nutty, and sometimes even pungent notes. The texture evolves, becoming firmer, denser, and more crumbly or creamy depending on the specific conditions. This patient aging is what truly develops the depth, character, and sophistication that defines Salguero’s vegan cheese, mirroring the maturation cycles of fine dairy cheeses.

   

The Blue Cheese Variation: A Further Innovation

Salguero also revealed the potential for a blue cheese variant. By using a pin to introduce specific blue cheese molds (such as Penicillium roqueforti) into the interior of the cheese after the initial dehydration phase, an entirely new flavour profile and aesthetic can be achieved. This demonstrates the versatility of his foundational method and opens avenues for further experimentation and diversification within the plant-based cheese category.

The Science Behind the Savour: Deconstructing the Innovation

Nico Salguero’s methodology is deeply rooted in scientific principles that have been utilized in food preservation and flavour development for millennia. The multi-step process leverages biochemistry, microbiology, and physics to transform humble almonds into a complex culinary experience.

The Power of Fermentation

Fermentation, at its core, is the metabolic process by which microorganisms convert carbohydrates into alcohol, gases, or organic acids. In Salguero’s cheese, lactic acid fermentation, driven by bacteria from the coconut kefir/yogurt or rejuvelac, is paramount. This process not only preserves the food by lowering pH but also generates a vast array of flavour compounds (esters, aldehydes, ketones) that contribute to the characteristic "cheesy" aroma and taste. The enzymes produced by these microbes also break down complex molecules, making the cheese more digestible and enhancing its nutrient profile.

Sprouting’s Nutritional Edge

The sprouting of almonds is a brilliant addition. Beyond making nutrients more bioavailable, sprouting activates specific enzymes (like amylase, protease, and lipase) that begin to predigest the almond’s components. This enzymatic activity contributes to the development of unique flavour precursors, some of which are known to enhance umami and create nutty, savory notes that are crucial for a truly "cheesy" experience. It’s a natural flavour enhancer that also improves the overall nutritional value.

Mimicking Dairy: The Art of Plant-Based Cheesemaking

Salguero’s genius lies in his ability to replicate the critical stages of traditional dairy cheesemaking using plant-based ingredients. The initial fermentation mirrors the "curd" formation; the controlled dehydration establishes a "rind" and manages moisture; and the brining and long aging periods directly parallel the techniques used to develop the flavour and texture of aged dairy cheeses like cheddar or Parmesan. This meticulous replication of process, rather than just ingredient substitution, is what elevates his cheese beyond simple alternatives.

The Growing Appetite for Plant-Based Cheeses

The emergence of such a sophisticated vegan cheese is particularly timely, coinciding with an unprecedented global surge in plant-based diets. Driven by increasing awareness of health, environmental sustainability, and ethical considerations, consumers are actively seeking high-quality alternatives to animal products. The vegan cheese market, in particular, has seen explosive growth, as cheese is frequently cited as one of the most challenging foods for individuals to give up when transitioning to a plant-based lifestyle.

Industry reports project the global vegan cheese market to continue its rapid expansion, potentially exceeding several billion dollars in the coming years. However, a common critique of many commercially available vegan cheeses is their texture (often rubbery or overly processed) and flavour (lacking the complex depth of dairy cheese). Nico Salguero’s aged almond cheese directly addresses these shortcomings, offering a product that can genuinely satisfy the discerning palate, thus raising the bar for the entire industry. His artisanal approach demonstrates that plant-based cheeses can indeed achieve the complexity, richness, and mouthfeel previously thought exclusive to dairy.
