If you're craving delicious sarim (colourful mung bean noodles in coconut syrup), MK Unigroup has the method for you. It isn't difficult to make, and for anyone curious we've included the history of sarim too.
The History of Sarim
The origins of sarim are unclear, but records show it was known in Ayutthaya by the late Ayutthaya period. When it comes to desserts of that era, one name stands out: Thao Thong Kip Ma, or Maria Guyomar, the "Queen of Thai Desserts", creator of famous sweets such as thong yip and thong yot that are known throughout the country. It has therefore been suggested that sarim might be one of the desserts she created.
Other sources suggest that sarim came from Java during the reign of King Borommakot. In his time many Malay nobles from Pattani served at the royal court under the care of two of his daughters, Princess Kunthon and Princess Mongkut, both of whom were very fond of Javanese culture. It is therefore believed that "sarim" was a dessert brought from Java to Siam in the late Ayutthaya period.
In the Kap He Chom Khrueang Khao Wan, a poem composed by King Rama II (Phra Phutthaloetla Naphalai), later generations learn only that sarim is sweet and eaten with coconut milk scented with borneol, without any description of the noodles themselves. The verse, in paraphrase, tells of sarim's lingering sweetness mingled with coconut milk, sprinkled with fragrant borneol.
The 2011 Royal Institute Dictionary simply describes it as a dessert made from mung bean flour, thin and long in shape, in many colours, and eaten with coconut milk and shaved ice, without specifying which colours.
