The most important person in the history of Thai desserts was Marie Guimar, a foreign lady who introduced several exotic desserts to Siam. The lady was born of a Portuguese father and a Japanese mother in Siam in the reign of King Narai (1656-1688). Marie was given the Siamese title and name of Thao Thong Kipma. Her husband was Constantine Phaulkon, a Greek sailor who rose to the highest non-hereditary rank of Chao Phraya Wichayen. Marie's husband gained special favour and trust from King Narai, causing envy and concern among the native courtiers. Unfortunately, after the king fell seriously ill, Phaulkon was arrested and put to death while Marie herself was sent to jail. Marie's life remained miserable until the reign of King Thaisa (1709-1733), who recognized the worth and abilities of the lady and put her in charge of the royal household with as many as 2,000 women working under her. This provided her with an opportunity to teach women in the palace the art of cooking, especially several desserts from Portugal with yolk and sugar as main ingredients, such as thong yip, thong yot, foi thong, sankhaya and mo kaeng. All of these have remained favourite sweets among the Thais up to the presents.
