Namkhaeng sai (, ) is a Thai version of shaved ice or snow cone. It is also known as wan yen () or chamba (). Namkhaeng sai is simply shaved ice in a bowl, poured on top with sweet syrup and condensed milk

Namkhaeng sai wasn’t recorded but is believed to be created in 1947 when the red sweet syrup was popular. There are several ingredients for namkhaeng sai. The main ingredients are shaved ice, sauces, and toppings.

Other desserts such as sarim, thapthim krop, and lot chong are partially similar to namkhaeng sai with different ingredients. Many desserts from other countries like bingsu and kakikori share characteristics with namkhaeng sai but the style of shaved ice (fine, rough, and strip length, etc.) and how toppings are decorated differs for each country of origin.

Nam Khaeng has been in Thailand for a very long time and thus it shares many histories with us. It is influenced by Thai culture in its taste, eating occasions, and naturally prominent hot weather. The same applies to Thai people too, some behaviors are induced by having namkhaeng sai in their daily lives.

History 
During the reign of King Rama IV (Mongkut) of Siam, ice was imported, leading to the construction of the first ice factory and consequently enabling the invention of namkhaeng sai. Ice was sent from Singapore, packaged inside a wooden crate, and transported by water on the steamboat named Chao Phrayam. Chao Phraya Phisonsombatboribun (Yim Bisalayaputra), titled Phra Phasisombatboribun, issued the ice order which was considered astonishing at that time.

In 1905, the first ice factory in Thailand was established by Phraya Bhakdi Noraset (Lert Sreshthaputra) at Saphan Lek, Charoen Krung Road. It was named "Siam Ice Factory"; people also called it "Nai Lert Ice Factory" which later on spread to suburbs around Bangkok. Ice was then adapted for use in desserts such as lot chong, Thai cantaloupe cake, sarim, thapthim krop, taro, and namkhaeng sai.

First namkhaeng sai originated from the Chinese in Phetchaburi province, combining shaved ice with pathongko and red syrup. Later in 1947, condensed milk was very popular and became one of the ingredients poured on top to flavor namkhaeng sai, which then was called chamba. There are two reasons for its name, first is that namkhaeng sais shape is similar to women's bosom and apparel color of chamba erotic dancer. The other reason is the distortion of the Teochew Chinese word chamba for its vague pronunciation.

Nowadays, chamba is modified to have diverse ingredients and make it more savory and valuable. Many restaurants use bread in namkhaeng sai but some may use cheesecakes or brownies. Additionally, not only has red syrup been used but also juice, tea, coffee, chocolate powder, or milk. Decorated with toppings such as fresh fruits, candied fruits, grain, jelly, crackers, cereal, and others according to each restaurant's idea. The dessert can easily be found in shopping malls, local markets, or street stalls. It is still one of the most popular cool-down desserts for everyone to date.

 Appearance 
Namkhaeng sai is by its meaning just ice getting shaved off by shaved ice machine or shaved ice table becoming ice flakes and piled up to make the shape of an ice mountain. This is the main part of the dessert namkhaeng sai. Next is putting the ice flakes into a container, usually a bowl or a cup in some shops, to prepare it for dressing with syrup and toppings. We then pour the syrup of choice on it to create different main flavors, some examples of these syrups are red syrup and condensed milk. The product we have right now is essentially a completed simplest form of namkhaeng sai and is ready to eat. However, to give it more textures and add variety to one’s preferences, nowadays shops always have choices for toppings to choose from; cereal, bread, and sticky rice are such toppings. After adding these to the bowl it is now ready to eat.

The namkhaeng sai mentioned above is sold at street stalls or small shops. In restaurants, namkhaeng sai may have its preset ingredients which come on different menus. Some of them also became signature dishes or portray the shop’s intentions and motivations.

 Cultural references 
In Thailand, namkhaeng sai perfectly correlates to how people perceive the weather, eating behavior, street food culture, childhood beliefs and lifestyle, or different opinions on the topic between generations.

 Weather and temperature Namkhaeng sai is said to be one of the desserts of choice to suppress smell from food and also to quench one’s thirst. Aligning with Thailand’s all-year-long hot weather, it is perfect for relieving the situation. In the recent past, in country areas or streets in cities, children who went home from school usually stopped by small shops selling ice cream or shaved ice to cool the heat off.

 Performance 
For namkhaeng sai, the name itself was once chamba, related to shows with the same name, "chamba erotic dancing". This show was very popular in the 1950s and is often held during temple fairs, where adults gather and watch the dance. The show is straightforward, female dancers will wear flashy, revealing clothes and dance on the stage. During the show, movements primarily involve flashing their genitals and shaking their breasts left and right to arouse audiences.

When vendors sell namkhaeng sai in these fairs where there is a chamba show, people who buy namkhaeng sai would relate its bulging shape to the dancers’ bosom. Red-colored syrup poured on top adds to the imagination as it resembles a flashy dress color worn by dancers. Furthermore, the action of “sprinkling” milk sounds and looks close to “shaking”, adding yet another naughty thought to relate namkhaeng sai with the chamba dance.

Nowadays, chamba cannot be found anywhere as these shows gradually lose their popularity over time, and thus the relation of the name "chamba" with namkhaeng sai is less used. Only a small number of people, presumably at the very least middle-aged and above, still remember this show and how come it is linked with the namkhaeng sai dessert.

 Notable shops Namkhaeng sai, although originated as street food and is commonly seen sold on roadsides or near communities in mobile stalls, is also sold in dedicated cafés which have their uniqueness and possess evident qualities as proper dessert restaurants. These stores would serve namkhaeng sai in multiple variants aside from its original form, notably Bingsu, providing customers with choices they preferred.

 Sai sai 
Saisai is a namkhaeng sai store using ingredients like vegetables, fruits, and local commodities to make namkhaeng sai toppings. Examples are 3-species pumpkins with Sago, Dahlia with fried onion, or Krill with Palm flower syrup. The café uses out-of-norm ingredients to make their servings but is made easy for people to eat despite their unfamiliarity. The place claimed that introducing these new tastes to people will also help farmers generate more income.

"Nature just got tastier" is the slogan of this place due to the founders’ intentions to promote local natural products by using them in their namkhaeng sai menus.

 Lukkaithong 
Lukkaithong, in the Emquartier shopping mall, was originally a restaurant with a Michelin guide guaranteeing its quality. Owners of Lukkaithong, Sangnarong Montriwat, and Kanchana Tathiyakul, thought of creating a signature dessert for their restaurant. They chose Thai tea to be the base for the dessert because it is one of the most popular beverages they knew. namkhaeng sai, shaved ice, was chosen to be that dessert due to their personal experience of enjoying it as a child to beat the heat, and easiness to eat and share with other people. So they combined Thai tea and namkhaeng sai, then through trial and error they arrived at the present menu's  pang cha''.

The two creators said that the idea of combining Thai tea with Namkhaneg Sai to make Pang Cha is not difficult to think up, but is hard to maintain consistency due to the nature of tea leaves differing in each season which affects taste and richness. So they had to adjust the recipe for each season to get the tea they wanted and set up the right combinations of fresh milk and condensed milk to make the ideal texture and consistency for the menu.

Pang Cha was originally just Thai tea shaved ice with bread. Toppings were then added, and three types of tapioca pearls: glass pearls for crunchiness, Thai tea pearls for color and aroma, and black tea pearls for texture and sweetness. White bread, almond slices, and whipped cream are also added as toppings. Shaved ice part of this menu is in the form of fluffy mountain from piled up thin ice floss.
