As sesame oil became more widely produced during the late Joseon period, its significance shifted from the exclusive domain of courts and temples to the broader sphere of rural and family life. While it was still not an everyday cooking fat for most households, its seasonal production and ritual applications made it an important marker of agricultural and cultural continuity. This period is crucial for understanding how sesame oil moved from an elite ingredient to a symbol of domestic identity.
In traditional Korean villages, the pressing of sesame oil typically occurred after the autumn harvest, a timing that aligned with both agrarian cycles and the preparation for major winter holidays. Anthropological accounts describe this pressing as a community-oriented activity involving multi-family labor, with equipment ranging from simple stone mills to larger wooden beam presses. The communal aspect matters: producing sesame oil required effort and cooperation, and in many cases, households received oil not only from their own harvest but also through reciprocal exchanges with neighbors. This created a sense of shared investment and reinforced the oil’s association with collective wellbeing.
The storage of sesame oil during this era was equally intentional. Ceramic onggi vessels—porous earthenware jars used widely across the peninsula—were partially buried to stabilize temperature. This method protected the oil’s chemical integrity, slowing oxidation and prolonging its usability in the absence of modern preservation techniques. Documents from regional magistrate offices even include notes on disputes over adulterated or diluted sesame oil, suggesting both its economic value and the need for regulatory oversight. These disputes demonstrate that sesame oil was by no means a casual household commodity; it was monitored, protected, and often contested.
Sesame oil also emerged as a key ingredient in Korean ritual life. In jesa (ancestral memorial rites), sesame oil was used to season specific ceremonial foods, not simply for flavor but to signal purity and respect. Folkloric accounts from regions such as Jeolla-do and Chungcheong-do describe the oil as symbolically “clean,” an attribute tied to its labor-intensive production and its perceived resistance to spoilage compared to animal fats. These understandings shaped its role in rites marking births, harvests, and the Lunar New Year. When families opened a fresh jar specifically for these ceremonies, the act underscored the importance of the event rather than the oil itself.
Folk beliefs further illuminate the oil’s cultural reach. In some regions, particularly rural mountain villages, small amounts of sesame oil were applied to children’s earlobes or foreheads as a protective measure against misfortune or illness. While these practices are no longer widespread, they appear in multiple ethnographic interviews from the mid-20th century, linking sesame oil to older shamanistic frameworks where oils and fragrances were believed to fortify the body’s boundaries. Whether or not such practices were empirically effective, they reveal the oil’s role as a household tool for both physical nourishment and symbolic protection.
These traditions were not uniform across Korea. Jeju Island, for instance, has documented cases of sesame oil being used to polish local stone guardian statues, a practice rooted in the belief that a maintained appearance signaled ongoing respect. Meanwhile, inland regions like Gangwon-do incorporated sesame and perilla oils into pre-winter festivals, where pressing demonstrations acted as public affirmations of agricultural readiness. Such variations illustrate that sesame oil was not a monolithic cultural object but a flexible one, adapting to regional beliefs and resources.
By the beginning of the 20th century, sesame oil had become firmly integrated into both the practical and symbolic systems of Korean domestic life. It remained expensive and difficult to produce, but its presence in rituals, seasonal labor, and inter-family exchanges positioned it as an essential component of cultural continuity. Its meaning expanded beyond cuisine into the realms of identity, protection, and tradition—an expansion that would shape how Koreans interpreted the ingredient well into the modern era.
