Early Cheese Making: American cheese origins trace back to 19th-century efforts to preserve cheese
The quest to preserve cheese in the 19th century was a driving force behind the creation of what we now know as American cheese. Before refrigeration, cheese makers faced the challenge of keeping their product edible for extended periods. Traditional methods like salting and waxing helped, but they often altered the cheese's texture and flavor. This need for a more stable, longer-lasting cheese set the stage for innovation, leading to the development of a uniquely American solution.
One key figure in this story is Jesse K. Wells, a dairyman from New York who, in the 1850s, began experimenting with blending different cheeses and adding preservatives. His goal was to create a cheese that could withstand the rigors of long-distance transportation and storage. By combining cheddar with other varieties and using sodium nitrate as a preservative, Wells produced a cheese that was not only durable but also had a consistent texture and mild flavor. This early version of processed cheese laid the groundwork for what would later become a staple in American households.
The process of making this new cheese involved shredding and melting different types of cheese, then mixing them with emulsifiers like sodium citrate to create a smooth, homogeneous product. This method not only extended shelf life but also allowed for the use of less expensive or imperfect cheeses, making it more affordable for the average consumer. By the late 19th century, companies like James L. Kraft began to refine and commercialize these techniques, further solidifying the place of processed cheese in American cuisine.
While the focus was on preservation, the result was a cheese that also catered to evolving consumer preferences. Its mild taste and meltability made it versatile in cooking, from grilled cheese sandwiches to cheeseburgers. This adaptability, combined with its affordability and longevity, ensured its popularity. However, it’s important to note that this early processed cheese was a far cry from the highly engineered versions that would emerge in the 20th century. The original goal was practicality, not perfection, and this distinction is crucial in understanding its historical significance.
For those interested in recreating early American cheese-making techniques, start by blending equal parts sharp cheddar and a milder cheese like Colby. Heat the mixture gently, adding a small amount of sodium citrate (about 2% of the cheese weight) to ensure a smooth texture. Avoid overheating, as this can cause the cheese to become rubbery. The result will be a cheese that pays homage to the ingenuity of 19th-century dairy farmers, offering a taste of history with modern convenience.

Kraft's Role: Kraft's innovation standardized production, making it widely available and affordable
American cheese, often synonymous with Kraft Singles, owes much of its ubiquity to Kraft’s pioneering role in standardizing its production. Before Kraft’s intervention in the early 20th century, cheese production was a localized, artisanal process with inconsistent quality and limited availability. Kraft’s innovation lay in developing a method to mass-produce a stable, shelf-stable cheese product that could be distributed widely. By combining natural cheeses with emulsifiers like sodium citrate, Kraft created a product that melted smoothly and resisted spoilage, addressing two major pain points for both producers and consumers. This breakthrough not only democratized access to cheese but also redefined what "American cheese" meant, transforming it from a regional specialty into a national staple.
Consider the logistical challenges Kraft overcame to make American cheese affordable and accessible. In the 1950s, Kraft introduced individually wrapped cheese slices, a packaging innovation that extended shelf life and reduced waste. This simple yet effective solution allowed families to purchase cheese in pre-portioned amounts, eliminating the need for frequent trips to specialty shops. For households on tight budgets, this meant cheese could be a regular part of meals without the risk of spoilage. Kraft’s ability to produce cheese at scale also drove down costs, making it one of the most cost-effective protein sources available. For example, a single pack of Kraft Singles in the 1960s cost roughly the equivalent of $2 today, providing a week’s worth of cheese for a family of four.
Kraft’s standardization of American cheese production also had a profound impact on culinary culture. By creating a product that melted consistently, Kraft enabled the rise of iconic American dishes like the cheeseburger and grilled cheese sandwich. These foods became symbols of affordability and convenience, particularly during the post-war economic boom when families sought quick, satisfying meals. Kraft’s cheese became a kitchen staple, its bright yellow slices instantly recognizable. For home cooks, the predictability of Kraft’s product meant recipes could be replicated with confidence, fostering a sense of culinary independence. This standardization extended beyond the home, too, as fast-food chains adopted Kraft’s cheese for its reliability and cost-effectiveness.
However, Kraft’s dominance in the American cheese market has not been without criticism. While the company’s innovations made cheese widely available, they also contributed to the perception of American cheese as a highly processed, less "authentic" product. Purists argue that Kraft’s focus on shelf stability and meltability came at the expense of flavor complexity. Yet, this critique overlooks the practical realities Kraft addressed: feeding a growing population with limited access to fresh, artisanal cheeses. For many, Kraft’s American cheese remains a nostalgic and functional food, a testament to the power of innovation in shaping dietary habits. Its role in standardizing production serves as a case study in how food technology can balance accessibility with tradition.
