# Tom yum kung

Tom yum kung, or Tom yum goong, (Thai: ต้มยำกุ้ง RTGS: tom yam kung) is the Thai spicy and sour shrimp soup—a variant of Tom yum, combined with many of Thailand's key herbal and seasoning ingredients, often served with a side of steamed rice, sometimes with a dollop of chili paste and a splash of lime juice, enhancing its spicy and tangy profile. Presently, there are two profiles of Tom yum kung recipes: Tom yum kung nam khon—a creamy broth with mellow and smooth flavor, and Tom yum kung nam sai—a clear broth with a stronger flavor.
Tom yum kung was listed as the 8th of CNN's world's 50 best foods in 2011 and was one of the best soups among CNN's 20 of the world's best soups in 2024.

## Etymology

In Thai, the term tom yum kung is a compound word of tom yum + kung. The term tom yum, which means spicy and sour soup, is a combination of two Proto-Tai words: *tom 'v. to cook in water, boil' + *yum, *yam 'v. to mix together or n. salad.' And the term kung, goong means prawn, shrimp, and crayfish.

### Variant names

In Chinese, the term dongyingong (Chinese: 冬荫功) is a loanword which is derived from the Thai terms tom yum, tom yam 'cooked in sweet and sour' + kung, goong 'prawn.'
The term tom yum kung is also written in various languages, such as tom yang kung (Korean: 똠양꿍), tomu yamu kun (Japanese: トムヤムクン), and in Burmese yodaya hinjo.

## History

The origin of Tom yum kung is deeply connected to the way of life and local wisdom of the Thai people, who have been fond of establishing riverside communities in the central plains and upper part of the Chao Phraya River basin since the Ayutthaya period. The Safine-ye Solaymani also mentioned variant terms shahr-i nāv, or shahr-i nau (Persian: شهر نو), literally "City of Boats, Canals," with reference to the Ayutthaya Kingdom. In Thai Literature, the Nirat Than Thongdaeng—the Journey to Than Thongdaeng River—bears eloquent testimony to the beauty of the forests, streams, and hills of the Phra Phutthabat area in Saraburi, composed by Prince Thammathibet, Viceroy of Siam (1732–1755), closely observes the animals and plants along the way. The stanzas No. 103 of the literature described the abundance of aquatic animal in the Ayutthaya period reads:
The traditional Tom yum kung recipe first appeared based on written evidence as Tom yum kung song khrueng—extra ingredients Tom yum kung spicy and sour shrimp soup in 1898, found in the book the Lexicon Dictionary of Sweet and Savory Recipes in Western and Siamese Styles compiled by students of Harriet M. House School For Girls at Wang Lang in Bangkok (now Wattana Wittaya Academy), which is different from today's Tom yum kung recipe.
The Tom yum kung recipe, which is similar to the modern Tom yum kung, first appeared in 1964 in the Food of the Royal book officially recorded by M.R. Kitinadda Kitiyakara, the former Thai secretary of the privy council in the reign of King Bhumibol Adulyadej (Rama IX). Therefore, based on the evidence, it is possible that Thai people have had recipes similar to Tom Yum Kung since the reign of King Chulalongkorn (Rama V) or earlier in the Rattanakosin period.
In 2011, Tom yum kung was registered as a National Cultural Heritage (NCH) of Thailand under the domain of knowledge and practice concerning nature and the universe in the food and consumption category.$^{:55}$
