This dish is a staple of Thai cuisine, particularly popular as a quick and flavorful meal and can be found in restaurants, food stalls and markets across Thailand.

The practice of eating out, especially purchasing prepared meals such as khao kaeng, is believed to have emerged during the reign of King Rama IV, following the signing of the Bowring Treaty in 1855.

[4] Lawan Chotamar, a writer, recounts that over a century ago, a well-known khao kaeng stall was run by a couple, Ta Peng and Yai Puk, at the Ban Mo intersection.

The stall, located near a large hall called Sala Ta Peng, became highly successful, and the couple amassed wealth from their khao kaeng business.

[6] Today, khao kaeng remains a popular and accessible meal, available in a variety of settings, including sit-down restaurants, food stalls, and even in gas stations.
