The culinary art of Kaili Sour Soup Fish is a signature national-level intangible cultural heritage from the Qiandongnan region of Guizhou. Inscribed on the fifth batch of the National List of Representative Intangible Cultural Heritage in 2021, it represents a traditional cooking technique passed down through generations of the Miao people. Rooted in the unique climate and local ingredients of the Yunnan-Guizhou Plateau, the dish centers on naturally fermented sour soup paired with fresh river fish from the Qingshui River. Renowned for its distinctive blend of sour, spicy, fresh, and aromatic flavors, it is not only a staple of daily Miao meals and festive hospitality but also embodies the survival wisdom of Miao ancestors—who learned to live in harmony with nature by preserving food through fermentation—and the rich folk culture of the Qiandongnan region.
Located in the heart of the Miao Mountains and along the upper reaches of the Qingshui River, Kaili, Guizhou, experiences a humid, rainy climate. In ancient times, when salt and seasonings were scarce, Miao ancestors ingeniously utilized local resources and climatic conditions to develop a natural fermentation technique for creating sour soup. By using acidity to replace salt and neutralize fishy odors, they gave birth to the Sour Soup Fish tradition that has endured for a millennium. A local proverb—"Without eating sour food for three days, one’s legs wobble while walking"—attests to how deeply ingrained the flavor of sour soup is in the lives of the local people. Refined over seventeen generations of Miao artisans, Kaili Sour Soup Fish has evolved from a humble rustic dish into a culinary calling card for Guizhou—a national-level intangible cultural heritage that balances the warmth of everyday life with profound cultural significance.
I. Intangible Cultural Heritage Status and Historical Origins
In May 2021, the culinary art of Kaili Sour Soup Fish was officially inscribed on the National List of Representative Intangible Cultural Heritage. Its practice is centered in Miao communities across Qiandongnan—including Kaili, Leishan, and Taijiang—and extends throughout the Miao Mountain region. With a history spanning a thousand years, the tradition traces back to the mountain-dwelling lives of Miao ancestors. Facing geographical isolation and a lack of salt, the Miao people developed a unique sour soup cooking system by using rice water, wild fruits, and chili peppers to create acidity through natural fermentation, thereby solving the challenges of food preservation and seasoning. Today, the culinary technique for Kaili Sour Soup Fish has been approved as a provincial standard for intangible cultural heritage in Guizhou. It stands as a model of the integrated development of "intangible cultural heritage plus industrialization," has won numerous domestic and international culinary awards, and enjoys nationwide renown.
II. Local Ingredients, Naturally Exquisite Flavors
The unique flavor of Kaili Sour Soup Fish stems from distinctive, indigenous ingredients; it requires little additional seasoning, possessing an inherent freshness and aroma derived from the wild landscape. The main ingredient is fresh river fish from the Qingshui River, prized for its tender, sweet flesh—free from any muddy aftertaste—making it ideal for cooking in sour soup. The signature sour soup comes in two varieties—white and red—both crafted through natural fermentation. The white sour soup is fermented from local glutinous rice water; it is clear in color, offering a mellow acidity with a sweet finish. The red sour soup is made from *maolaguo* (a local wild tomato variety) and local pickled chili peppers; it boasts a vibrant red hue and a rich, spicy-sour profile. These are complemented by wild seasonings such as *mujiangzi* (mountain pepper/litsea cubeba), *yuxiangcai* (fish-mint/houttuynia), fresh Sichuan peppercorns, and tender ginger. This harmonious blend of meat and vegetables creates a complex, layered flavor profile—an authentic taste of Guizhou that industrial seasonings cannot replicate.
III. Traditional Preparation Process: Natural Fermentation and Artisanal Cooking
Kaili Sour Soup Fish adheres to ancient Miao methods, relying entirely on natural fermentation and manual preparation without industrial additives. The process involves meticulous steps and precise heat control, embodying the culinary wisdom of the Miao people. The core process consists of four main stages:
Step 1: Traditional Fermentation. For the white sour soup, thick glutinous rice water is cooled and placed in a fired clay jar; a "starter" of heirloom sour soup is added, and the mixture is left to ferment naturally near a hearth at room temperature for five to six days, resulting in a mellow, fragrant broth. For the red sour soup, chopped *maolaguo* and fresh chili peppers are sealed in a jar to ferment, locking in the natural acidity and aroma of the produce; this serves as the soul of the dish, with the fermentation starter passed down through generations—growing more aromatic with age.
Step 2: Preparing the Fresh Fish. Fresh river fish are selected and cleaned by hand to remove any fishy odor while preserving their natural sweetness. They are neither marinated nor deep-fried; instead, the process maximizes the retention of the fish's tender texture, ensuring the meat remains firm and intact after cooking.
The third step involves preparing the soup base. Aromatics such as ginger, Sichuan peppercorns, and *Litsea cubeba* (mountain pepper) are sautéed in a hot wok. Fermented sour soup is then poured in and brought to a boil over high heat. Ingredients like bean sprouts and tofu are added to form the base, balancing the soup's acidity and astringency to create a rich, savory flavor profile with a harmonious blend of sour and spicy notes.
The fourth step is cooking over high heat. Once the soup boils, the fresh fish is added and simmered over high heat for over ten minutes. Skilled artisans carefully control the temperature to ensure the fish is thoroughly cooked yet holds its shape, absorbing the flavors without becoming tough or dry. Before serving, the dish is garnished with *Eryngium foetidum* (often called "fish-scented herb") to enhance the aroma, resulting in a pot of Miao-style sour soup fish that is refreshing, spicy-sour, and rich in flavor.
IV. Folk Customs and Culinary Value
Kaili Sour Soup Fish has long transcended the realm of ordinary cuisine, becoming deeply integrated into the folk life of the Miao people. In Miao communities, this dish is a staple for festivals, weddings, and the reception of honored guests, symbolizing abundance year after year and a life rich in both sour and sweet experiences. The technique of natural fermentation reflects the survival wisdom of the Miao ancestors, who adapted to the mountainous climate and developed methods to preserve ingredients; this practice not only solved the ancient challenge of food preservation but also gave rise to a unique culinary system defined by sour and spicy flavors. A pot of sour soup fish embodies the agricultural customs, dining etiquette, and collective memory of the Miao Ridge region, serving as a vivid embodiment of the local culture of Southeast Guizhou through taste.
V. Heritage Preservation and Innovative Development
For generations, the craft of making Kaili Sour Soup Fish has been passed down within Miao families and through master-apprentice relationships, steadfastly adhering to traditional fermentation and manual cooking methods. Today, supported by national policies for the protection of intangible cultural heritage, a comprehensive inheritance system has been established. Veteran artisans uphold traditional fermentation techniques and preserve authentic Miao flavors, while younger inheritors keep pace with the times by innovating pre-packaged sour soup bases and unique serving styles, thereby driving the standardization and industrialization of the craft. The industrial chain for Kaili Sour Soup has matured significantly, with outlets now found across the country; this success has preserved the authentic taste of this millennia-old Intangible Cultural Heritage while bringing the wild, rustic flavors of the Miao Mountains to a nationwide audience.
VI. Summary of Intangible Cultural Heritage Value
The culinary art of preparing Kaili Sour Soup Fish represents a perfect fusion of nature’s timing and human craftsmanship. A single jar of fermented sour soup embodies a thousand years of Miao customs, while a pot of fresh fish stew captures the essence of the Guizhou highlands. It is not merely a delicious delicacy; it is a vivid microcosm of the survival wisdom, folk etiquette, and local culinary culture of the Miao ancestors—a cherished Guizhou Intangible Cultural Heritage treasure that remains deeply rooted in the Miao Mountains and continues to thrive.
