Fios de ovos
Portuguese egg-yolk strands spread globally through trade and colonization.
Fios de ovos, meaning "egg threads," is a Portuguese sweet made by drizzling egg yolks into thin strands and cooking them in sugar syrup. It can be eaten by itself, used as a cake or pudding garnish, or stuffed inside pastries. Portuguese traders and colonizers carried the dessert across Asia, where it took on different names and local twists. In Japan it is called *keiran sōmen* (hen egg noodles), in Cambodia *vawee*, in Malaysia *jala mas* (golden net), in Thailand *foi thong* (golden strand), and in Kerala, India, *muttamala* (egg chain or necklace). In Goa it is known as *letria*. The dish is also popular in Brazil and Spain, where it is called *huevo hilado*; in Seville it is shaped into peaked cones known as *yemas de San Leandro*.
Like many Portuguese egg-based sweets, fios de ovos is thought to have been invented by nuns in the 14th or 15th century. Convents and monasteries used egg whites to starch laundry, leaving a large surplus of yolks. Between the 16th and 18th centuries, Portuguese explorers brought the recipe to Japan, Thailand, and parts of India.
In Brazil, fios de ovos tops the Marta Rocha Torte, a cake named after Miss Brazil 1954 Martha Rocha. In Kerala’s North Malabar region, the Portuguese introduced the dish, which became *muttamala*—egg yolk threads cooked in sugar syrup—and remains a lasting culinary mark of 16th-century Portuguese influence. In Cambodia, *vawee* is garnished with bright candied fruit like cherries and reserved for special occasions; according to chef Longteine De Monteiro, its origin is Thai and, before that, royal Khmer, and it is sold only in a few Phnom Penh shops by women who once lived in the Royal Palace. In Laos, *foi thong* is one of the hardest desserts to make, boiled in pandanus-flavored sugar syrup, and traditionally served at weddings and ceremonies where the long threads symbolize a long life. In Thailand, *foi thong* gets its name from its fine, shiny, silk-like strands; introduced by Maria Guyomar de Pinha (half Portuguese, half Japanese, born and raised in Thailand), it is considered a fine dessert, and the word *thong* (gold) carries auspicious meaning, with the long strands representing long life and undying love. In Japan, *keiran sōmen* is one of the *nanbangashi*—desserts introduced from Portugal during the Nanban trade.

Lore & Background
Like other egg-based Portuguese sweets, fios de ovos is believed to have been created by Portuguese nuns around the 14th or 15th century. Laundry was a common service performed by convents and monasteries, and their use of egg whites for 'starching' clothes created a large surplus of yolks. Between the 16th and 18th centuries Portuguese explorers took the recipe to Japan, Thailand and parts of India.
In Brazil, fios de ovos is used as a topping for Marta Rocha Torte, a cake named after Miss Brazil 1954 Martha Rocha. In the North Malabar region of Kerala, India, the Portuguese-introduced fios de ovos was adapted into a local variation known as Muttamala, a sweet made of egg yolk threads cooked in sugar syrup. In Goa, this dish is known as letria.
In Cambodia, fios de ovos is called voy or vawee, garnished with bright candied fruit such as cherries, and reserved only for special occasions. According to Cambodian chef Longteine De Monteiro, vawee's origin is Thai and before that, royal Khmer. In Laos, foi thong is boiled in pandanus leaf-flavoured sugar syrup and traditionally served at weddings and other ceremonial occasions, where the length of the egg threads symbolises long life.
Reader's Guide
Fios de ovos holds significance as a culinary artifact of Portuguese exploration and colonial influence, spreading from its likely origin in medieval convents to diverse regions across Asia and the Americas. In Japan, it is known as keiran sōmen and is one of the nanbangashi, desserts introduced from Portugal during the Nanban trade. In Thailand, it is called foi thong, introduced by Maria Guyomar de Pinha, a half Portuguese and Japanese woman born and raised in Thailand; the word thong ('gold') has auspicious connotations, and the long strands symbolize long life and undying love. In Malaysia, it is called jala mas ('golden net'), and in the Malabar region of Kerala, India, muttamala ('egg chain' or 'egg necklace'). In Spain, it is known as huevo hilado, and in Seville it is shaped into peaked cones called yemas de San Leandro. The dish's legacy is seen in its continued use in Portugal and Brazil as fillings, cake decorations, and accompaniments for sweet and savory dishes, including with Christmas turkey in Brazil. In North Malabar, India, it is typically prepared for weddings and festive occasions, often served with pinjanathappam, a steamed pudding made from egg whites. The dish's adaptation across cultures demonstrates how a simple egg-yolk preparation became a versatile symbol of celebration and auspiciousness.
