English: Foi thong (Thai script: ฝอยทอง) are strands of egg yolk dropped in to a jasmine scented sugar syrup. The, originally Portuguese, delicacy was introduced to Thailand in the 17th century by Maria Guyomar de Pinha, a Catholic Siamese woman who was born to a Japanese mother and a Portuguese/Bengali father. The original Portuguese dish is called "fios de ovos" (egg threads).
