Tam mak hoong (Lao papaya salad) Period BOrigin theory CVerified

Tam mak hung is an uncooked salad. Firm, unripe green papaya is shredded into thin strands and pounded in a wooden mortar with padaek—a thick sauce of fermented fish—and chili, the pounding bruising the fibers so the flavors soak in. That handwork with mortar and pestle is the heart of the dish, and it is made the same way in home kitchens and at market stalls.

Both the green papaya at its center and the chili that gives it heat came originally from the New World; until those crops crossed the ocean and settled into what is now the Thai-Lao world, the salad in its present form had no way of coming into being. The French envoy Simon de la Loubère, writing his account of the kingdom in 1693, records that papaya was already growing widely across Siam. The mortar-and-pestle pounding and the culture of fermented fish sauce were long established here; when green papaya and chili arrived, the shape of this dish settled into place.

In Laos the salad is no mere side dish. Eaten with sticky rice, it is treated as a national food, part of the everyday table.

The origins of tam mak hung come down to a few competing views.

One takes the Lao people as the makers of the original pounded green-papaya salad. A Thai travel poem of 1869, the Nirat Wang Bang Yi Khan, mentions pounded papaya as the food of a Lao royal held in Bangkok. The memoir of the Lao statesman Katay Don Sasorith (1958) records that it was already a Lao favorite in Paksé in the 1910s. Kristine Callis's study of the history of plant use in Laos (2005, North Carolina State University), reading European explorers' accounts from 1545 to 1861, showed that by the time travelers such as Pallegoix and Mouhot arrived, papaya and chili were fully woven into Lao life. On this view the salad passed through Isan—home to many Lao—into Thailand, where it settled as som tam.

The other view holds that the Lao tam mak hung and the Isan Thai som tam are essentially one dish, and that which came first is undecided. Ingredients and method are shared, and Lao communities have long lived on both sides of the border. The Thai historian Sujit Wongthes and the food researcher Hanuman Aspler argue instead that the dish took shape among Lao communities who had moved into central Thailand. The earliest recipe set down in writing is the som tam mamalakor that appears as a dish in its own right in a Bangkok cookbook of 1929, the Tamra Khraawp Lohk. But that is the first time it reached print, not the moment the dish was born.

What is certain is that tam mak hung and som tam are two names for the same green-papaya salad. Eaten widely across borders and peoples, it reflects less a question of who came first than a food culture that straddles Laos and Thailand together.
