Kimchi as Korean fermented-food heritage in everyday meal practices: a qualitative focus group study in the United States and United Kingdom

Food is rarely just about taste. While flavor matters, what we eat is also shaped by how we fit new items into the routines of our daily lives. A person might love the idea of a new dish but still not serve it because they do not know how to store it, when to eat it, or what to serve it with. This gap between liking a food and actually using it is a central question for researchers who study how people make choices. They look at the practical skills, or "competence," that turn a strange ingredient into a normal part of a meal. When a food is also a cultural tradition, carrying deep history and specific rules about preparation, the challenge grows. People must navigate not only the sensory experience of the food but also the weight of its heritage. Understanding how a food moves from a museum piece or a restaurant novelty to a staple on a home dinner plate requires looking at the small, practical steps people take to make it their own.

A team of researchers from the World Institute of Kimchi set out to understand this process with kimchi, a fermented vegetable dish from Korea. Kimchi is not a single recipe but a living tradition that has evolved over centuries. It begins with salting vegetables to preserve them through the winter, a practice that once ensured survival in a climate with harsh cold seasons. Over time, the dish incorporated red peppers, garlic, ginger, and fermented seafood, creating a complex, sour, and spicy food that changes as it ferments. In 2013, the communal act of making kimchi for the winter, known as kimjang, was recognized by UNESCO as an intangible cultural heritage. Today, kimchi is available in supermarkets and restaurants across the United States and the United Kingdom, yet many people still hesitate to include it in their everyday meals. The researchers wanted to know why. They asked how people in these two countries understand what kimchi is, how they interpret its strong smells and changing textures, and what practical knowledge helps or stops them from using it at home.

To find answers, the researchers gathered fourteen adults in four online group discussions in August 2023. The group included six people from the United States and eight from the United Kingdom. The participants were chosen carefully to represent different levels of experience. Some ate kimchi frequently, some tried it occasionally, and some had never eaten it at all but were aware of it. None of the participants had Korean heritage or had lived in Asia for a long time, ensuring the study reflected the perspective of outsiders encountering the food. The groups met for about ninety minutes, guided by a moderator who asked them to discuss their experiences, their first impressions, and how they imagined using kimchi. The researchers showed the participants pictures of different types of kimchi, such as the classic cabbage version, a broth-rich water kimchi, crisp cucumber varieties, and radish-based forms, as well as images of kimchi served with familiar foods like tacos, fried rice, and burgers. The goal was not to count how many people liked it, but to listen to how they talked about it and to map out the different ways they made sense of the dish.

The conversations revealed that people first try to understand kimchi by comparing it to things they already know. Many participants struggled to place it in a meal. Some called it a side dish, others a pickle, a salad, or a condiment. For those who had never eaten it, the uncertainty was sharp. One person in the United Kingdom said they had no idea if it was a starter, a main course, or a dessert until they tried it. Another described it as a side salad that went well with curry, but admitted they could not imagine eating vegetables as a main meal on their own. Even for those who had tried it, the sensory experience was a hurdle. The smell, the sourness, and the texture of fermentation caused hesitation. Some described the smell as potent or the taste as almost rotten, like food left out in the sun too long. These reactions were not just about disliking the flavor; they were about not knowing how to interpret the signals of a living, fermenting food.

However, the study found that these sensory barriers could be overcome when people gained practical knowledge. The researchers identified four different positions that people held, ranging from those who used kimchi every day to those who had not yet tried it. The most experienced group, who ate kimchi at least once a week, treated it as a flexible household resource. They did not just eat it with Korean food; they added it to scrambled eggs, salads, crepes, and stir-fries. They knew how to buy it, how to store it, and how to adjust the portion to fit their meal. They had built a routine where kimchi was a normal tool for adding flavor and acidity. In contrast, those who ate it less often or had only tried it a few times showed what the researchers called "partial incorporation." They were open to the idea and could imagine using it with familiar foods like tacos or fries, but they lacked the confidence to prepare it at home. They preferred to try it in a restaurant first and were unsure about making it themselves.

The group that had never eaten kimchi but knew about it faced a different kind of barrier. They were not necessarily afraid of the taste, but they felt they lacked a script for how to use it. They wanted to know what was in it, how it should be served, and whether it should be eaten hot or cold. One participant said they did not like to be surprised when eating something new and wanted a first tasting prepared by someone who knew what they were doing. For this group, the problem was not a negative opinion but an absence of practical guidance. They knew kimchi was a Korean heritage food and that it was healthy, but they did not know how to translate that knowledge into a meal. The researchers noted that cultural authenticity, while interesting, did not automatically tell people how to cook or serve the food. In fact, the desire for an "authentic" experience sometimes made people more hesitant to try fusion versions, leaving them stuck without a clear way to start.

The study suggests that for a culturally distinct food like kimchi to become part of everyday life, it requires more than just visibility or health claims. It requires practical competence. People need to know how to buy the right kind, how to store it so it does not spoil, and how to pair it with foods they already eat. The researchers found that when people could move from recognizing kimchi as a Korean tradition to knowing how to handle it in their own kitchen, the food became easier to incorporate. The strong flavors and changing textures of fermentation were not fixed barriers but features that could be understood and managed once the practical steps were clear. The study does not prove that everyone will eventually eat kimchi, nor does it claim that the findings apply to all consumers in the United States or the United Kingdom, as the group was small and carefully selected. However, it offers a clear picture of the gap between curiosity and routine. It shows that the path to making a new food a part of daily life is paved with concrete knowledge about how to use it, not just with an appreciation of its history or its taste.
