This high praise underscores the significance of Salguero’s achievement, positioning his methodology as a potential benchmark for future vegan cheese development.

The cheese is crafted primarily from almonds, undergoing a multi-stage process that includes soaking, sprouting, grinding with fermented cultures, multiple fermentation periods, specific dehydration cycles, brining, and an extended aging period. Each step is carefully orchestrated to develop complex flavors, desirable textures, and a stable, age-worthy product. The ability to create a blue cheese variation further highlights the versatility and sophistication of Salguero’s technique, suggesting that this foundational process could lead to a diverse range of artisanal vegan cheeses. This innovation is particularly pertinent given the global surge in demand for high-quality, plant-based food options, and its origin in Buenos Aires — a city renowned for its traditional meat and dairy culture — makes it all the more compelling.

Chronology: The Art of Aged Vegan Cheese Production

Nico Salguero’s process is a testament to patience, precision, and a deep understanding of fermentation. It mirrors, in many aspects, the time-honored traditions of artisanal dairy cheesemaking, adapted ingeniously for plant-based ingredients.

Soaking and Sprouting: Awakening the Almonds

The journey begins with soaking raw almonds in water for approximately 24 hours. This crucial initial step serves multiple purposes: it softens the almonds, making them easier to process, and begins to activate enzymes that will aid in subsequent stages. Following the soak, the skins are meticulously removed. This not only improves the final texture of the cheese, preventing any gritty residue, but also eliminates potential bitter compounds found in the almond skins.

The next stage, sprouting the soaked almonds, is vital for nutrient bioavailability and flavor development. The almonds are kept moist but drained, allowing them access to air, for about two days, with periodic rinsing. Sprouting transforms the almonds, increasing their enzyme content, making their nutrients more digestible, and contributing a subtle, fresh sweetness that will later evolve into complex notes during fermentation and aging. This step is a cornerstone of many traditional food preparations, harnessing the natural life force of the ingredient.

Culturing and Initial Fermentation: The Birth of Flavor

Once sprouted, the almonds are ground into a thick paste. This is where the magic of fermentation truly begins, as the paste is combined with a starter culture. Salguero specifies using fermented coconut milk yogurt or kefir, or alternatively, rejuvelac of alfalfa. These live cultures introduce beneficial bacteria, primarily lactic acid bacteria, which are responsible for the characteristic tangy, savory flavors and the preservation qualities of cheese. The choice of starter profoundly influences the flavor profile, contributing depth and complexity.

The almond paste, now inoculated with beneficial microbes, undergoes its initial fermentation for 24 hours at approximately 25°C (77°F). This temperature is ideal for the rapid proliferation of the starter cultures, allowing them to convert sugars into lactic acid and other flavor compounds, laying the foundation for the cheese’s distinctive character.

Shaping and Controlled Dehydration: Building Structure and Complexity

After the initial fermentation, the soft almond mixture is formed into the desired shape. This artisanal step allows for individual creativity and prepares the cheese for its structural development.

The formed cheese then undergoes a critical dehydration phase for about four days at a low temperature, around 20°C (68°F). The goal here is not to completely dry the cheese, but to form a dry crust or rind on the exterior. This rind provides structural integrity, making the cheese easier to handle, while crucially, the interior retains sufficient moisture to allow fermentation to continue slowly and develop further complexity. This controlled drying mimics the initial stages of affinage (aging) in traditional cheesemaking, where surface molds and yeasts begin to colonize, contributing to flavor and texture.

Brining: The Ancient Art of Preservation and Flavor

Following the initial dehydration, the cheese enters the brining stage. Starting on the fourth day of dehydration and continuing for three additional days, the cheese is submerged in seawater or a 5% brine solution (50 grams of salt per liter of water) three times each day. This salting technique is precisely how many aged dairy cheeses are traditionally salted. Brining serves multiple vital functions: it draws out excess moisture, inhibits spoilage bacteria, firms the rind, and most importantly, infuses the cheese with salt, which is fundamental for flavor development and preservation. The precise concentration of the brine is key to achieving the perfect balance.

Secondary Dehydration and Long-Term Aging: The Culmination

After the intensive brining process, the cheese requires a secondary dehydration period of approximately five more days at a cooler temperature, about 10°C (50°F). If a dehydrator capable of this lower temperature is unavailable, a refrigerator can serve as an effective alternative. This slower, cooler drying further stabilizes the cheese, continues to develop the rind, and prepares it for the final, most transformative stage.

The culmination of Salguero’s process is the aging of the cheese for 3-6 months at cool ambient temperatures. This extended aging period is where the cheese truly matures, allowing enzymes and microbial activity to break down proteins and fats, creating a symphony of complex flavors, aromas, and a desirable firm yet creamy texture. It is during this time that the cheese develops its deep, savory, and unmistakably "cheesy" characteristics.

The Blue Cheese Variation: Expanding the Horizon

Nico Salguero also revealed the exciting possibility of creating a blue cheese variant. By using a pin to carefully insert blue cheese molds (such as Penicillium roqueforti) into the interior of the cheese after the initial dehydration, the characteristic veins and pungent flavors of blue cheese can be developed. This demonstrates the incredible versatility and potential of his foundational method, opening doors for a wide array of specialized vegan cheeses.

Supporting Data: The Rise of Plant-Based Gastronomy and the Science Behind the Craft

Salguero’s innovation arrives at a pivotal moment for global food systems. The plant-based food market is experiencing unprecedented growth, driven by increasing consumer awareness of environmental sustainability, ethical considerations regarding animal welfare, and perceived health benefits. However, while plant-based alternatives for milk, meat, and yogurt have become mainstream, truly convincing aged vegan cheeses have remained a significant challenge. Many commercially available vegan cheeses often rely on starches, oils, and artificial flavorings, falling short of the textural and flavor complexity of artisanal dairy cheeses.

This is precisely where Salguero’s work stands out. His method leverages ancient fermentation techniques and the inherent qualities of whole foods, specifically almonds. Almonds are an excellent base for vegan cheese due to their creamy texture when blended, their mild flavor, and their nutritional profile, which includes healthy fats, protein, and fiber.

The science behind Salguero’s process is fascinating. Sprouting almonds activates enzymes like lipase and amylase, which break down fats and carbohydrates, making them more digestible and potentially enhancing flavor precursors. Lactic acid fermentation, facilitated by the coconut milk cultures or rejuvelac, is the cornerstone. Lactic acid bacteria (LAB) convert sugars into lactic acid, which lowers the pH, inhibiting spoilage organisms and contributing to the characteristic tang. Beyond lactic acid, LAB produce a myriad of volatile compounds (e.g., diacetyl for buttery notes, various esters for fruity aromas) that contribute to the complex flavor profile of aged cheese.

The controlled dehydration and brining processes are critical for moisture management and the development of a protective rind. The rind acts as a breathable barrier, allowing the cheese to "sweat" and interact with ambient microorganisms while preventing excessive moisture loss or spoilage. Salt, beyond flavor, plays a crucial role in water activity, creating an environment unfavorable for many pathogenic bacteria and influencing enzymatic activity during aging.

Finally, the extended aging period at cool temperatures allows for a slow and deliberate enzymatic breakdown of proteins (proteolysis) and fats (lipolysis). These processes generate amino acids and fatty acids, which are the building blocks of complex umami and savory flavors that define truly aged cheese. The microflora that colonize the rind during aging also contribute their unique enzymatic activities and volatile compounds, adding layers of aromatic complexity. Salguero’s precise temperature control at each stage ensures that the right microbial communities thrive, guiding the cheese’s evolution towards its intended flavor and texture.

The fact that this innovation hails from Buenos Aires, a city deeply rooted in a culinary tradition centered around asado (barbecue) and dairy products, is particularly noteworthy. It signifies a growing openness and a dynamic shift within the Argentine culinary landscape towards plant-based alternatives, demonstrating that even in bastions of traditional gastronomy, innovation is flourishing.
