As summer heat waves grip much of the world, the craving for a cool scoop of ice cream remains as timeless as the treat itself. According to historians and food scholars, the origins of this beloved dessert stretch back more than 2,500 years, beginning in the arid deserts of ancient Persia. What started as a practical innovation for storing ice in scorching climates has evolved into a global indulgence, with roots that weave through empires, scientific breakthroughs, and royal kitchens.
The story begins around 550 BCE in Persia, now modern-day Iran, where ingenuity met necessity. Ancient Persians developed yakhchals, massive stone structures shaped like beehives, designed to harvest and preserve ice year-round. These 'ice pits,' as they are sometimes called, featured deep subterranean storage insulated against the desert heat. High domes vented hot air upward, while wind catchers drew cooler breezes into the base, creating an early form of natural air conditioning.
Building these yakhchals was no small feat. Constructed in remote desert areas, they relied on winter canals to fill shallow, shaded ponds with fresh water. As overnight temperatures plummeted in the dry air, evaporation cooled the water into ice. Some yakhchals, enduring centuries of erosion, still stand across Iran in regions cold enough for natural ice formation or near mountains for harvesting. A study of a 400-year-old yakhchal in Meybod, Iran, estimated its annual output at 50 cubic meters of ice—equivalent to roughly 3 million standard ice cubes.
With a steady ice supply secured, Persians turned it into early frozen delights. Stored ice chilled fruit sorbets, sharbats—a sweetened fruit drink—and faloodeh, a refreshing mix of frozen rosewater and vermicelli noodles sweetened with honey syrup. These treats offered respite from the relentless summer sun, much like today's ice cream cones at a beachside stand.
The spread of this technology accelerated after the Arab conquest of Persia around 650 CE. As the method for ice production and storage disseminated across the Middle East, it inspired new variations. In Syria and Persia, milk and sugar were frozen with salep flour—made from powdered orchid roots—and mastic, the dried sap from an evergreen bush, to create stretchy forms of ice cream known as booza and bastani. These innovations marked a shift from simple sorbets to creamier confections.
Meanwhile, in China during the Tang Dynasty from 618 to 907 CE, a similar frozen dessert emerged. Called sushan, or 'crispy mountain,' it was crafted by melting, straining, and molding goat's milk curd into mountain-shaped metal forms. The poet Wang Lingran described its texture in his writings as 'somewhere between a liquid and a solid, melting in his mouth,' capturing the delicate balance that would define future ice creams.
Centuries later, European advancements propelled frozen desserts into the modern era. In 1558, Giambattista della Porta published Magia Naturalis, a compendium of natural science, astrology, and alchemy. The book included a groundbreaking recipe for rapidly chilling wine using saltpetre, or potassium nitrate, mixed with snow. 'Cast snow into a wooden vessel, and strew into it Salt-peter, powdred, or the cleansing of Salt-peter, called vulgarly Salazzo. Turn the Vial in the snow, and it will congeal by degrees,' della Porta instructed. This technique exploited the chemical's ability to draw heat from its surroundings, making freezing liquids far more efficient.
By the 17th century, experimenters discovered that a simpler mixture of ordinary salt, water, and ice produced a similar effect. This allowed smaller ice stores to chill mixtures on demand, democratizing the process. Coupled with abundant sugar from Caribbean plantations, which prevented mixtures from hardening into solid blocks, these methods laid the groundwork for creamier textures. Sugar's role was crucial, as it lowered the freezing point and ensured smooth consistency.
The race for the 'first' true ice cream recipe heated up in the late 17th century, pitting France against Italy in a culinary rivalry. In 1692, Nicolas Audiger, a steward who had served Jean-Baptiste Colbert, the chief minister to King Louis XIV, published La maison réglée, a handbook for noble households. Audiger, fresh from 18 months in Italy, detailed recipes for fruit sorbets and a pioneering ice cream flavored with orange blossom water and sweetened with sugar. His instructions emphasized stirring and scraping the mixture for even texture distribution, techniques that refined Italian methods into the creamy results we recognize today.
Just two years later, in 1694, Alberto Latini, steward to Cardinal Francesco Barberini—nephew of Pope Urban VIII—released Lo Scalco alla Moderna. Latini's 'milk sorbet' recipe combined milk, sugar, water, and candied fruits, incorporating exotic ingredients like chocolate and tomatoes available to elite Roman households. This is widely regarded as a precursor to Italian gelato, with its smoother, denser profile compared to French styles.
Scholars debate which came first, but both claims hold weight. Audiger's work, influenced by his Italian sojourn, built on existing knowledge, while Latini's aligned with avant-garde cooking trends in papal circles. According to food historian Mark Wiens, who has studied these texts, 'Audiger’s detailed scraping method was key to achieving creaminess, but Latini’s use of milk pushed boundaries in flavor innovation.' Neither side yields definitively, reflecting the cross-cultural exchange that shaped the dessert.
From these aristocratic origins, ice cream spread to the masses. In the 18th and 19th centuries, street vendors in Europe and America hawked frozen treats, evolving into parlor favorites. Innovations like hand-cranked freezers in the 1840s, patented by Nancy Johnson in the U.S., made home production feasible. By the 20th century, brands like Ben & Jerry's in Vermont turned it into a cultural icon, even tying prices to weather in quirky promotions—dropping costs as temperatures fell below freezing.
Today, ice cream consumption defies climate expectations. While one might assume hotter regions lead in per capita intake, the top spot belongs to New Zealand, followed by the United States and Australia. Surprisingly, cold-weather nations like Finland, Sweden, Canada, and Denmark round out the top seven. This 'ice cream paradox,' as some call it, suggests the treat serves dual purposes: cooling relief in heat and comfort in chill. As global temperatures rise, experts predict increased demand, with sustainable sourcing of ingredients like sugar and dairy becoming a pressing concern.
Looking ahead, the legacy of ancient yakhchals informs modern refrigeration, while debates over origins remind us of ice cream's unifying appeal. Whether scooping faloodeh in Iran or gelato in Rome, the dessert bridges millennia, offering a sweet escape from whatever the weather brings. As one anonymous Persian proverb noted, passed down through generations, 'In the pit of summer, ice is the jewel of the desert.'
In Appleton, where local creameries buzz with summer crowds, this history adds flavor to every cone. Residents like dairy farmer Elena Vasquez, who supplies milk to regional shops, appreciate the long journey. 'It's amazing to think our ice cream traces back to those ancient ice makers,' she said. 'Keeps things cool, literally and figuratively.'
