This dish (Khao Soi Recipe) takes us back in time to the mid-19th century. The trade caravans were trailing the jungles of northern Thailand along the ancient routes between India and China. Those long caravans were carrying wealth of exotic goods, leaving rich aroma of spices and the sweet scent of opium as they passed.
The men on this long line of between fifty and one hundred mules would be Yunnanese Muslim Chinese, who dominated the trade routes and began to settle in Chiang Mai and the main towns of north Thailand at that time.
