Khao soy
This Northern Thai staple, commonly doused in a creamy and spicy broth, and served with chicken, actually has Chinese origins. The history of this soupy dish can be traced back to the Muslim-Chinese tribes, called Hui or Chin Haw, that lived in the Yunnan province of Southern China. These peoples regularly frequented Northern Thailand for trade. According to Siriluck Bangsud and Ponlawat Arom in Delicacies in Lanna (Ocha in Lanna), when the Kuomintang party led by Chiang Kai-chek was exiled to Taiwan from China as the party was defeated by the Communist party in the Chinese civil war in 1949, some of the Kuomintang supporters including the Chin Haw migrated to the north of Thailand to escape conviction. Some of them who could not return to their motherland settled down in the north and started business, which includes khao soy restaurant. The original khao soy recipe is similar to Yunannese papa soy — the white noodle dish with light broth. The recipe was later adapted to appease the Thai palate with the addition of coconut milk.
