Fios de ovos
Angel hair, called in Portuguese fios de ovos ("egg threads") is a traditional Portuguese sweet food made of eggs (chiefly yolks), drawn into thin strands and boiled in sugar syrup. They are a traditional element in Portuguese and Brazilian cuisine, both in desserts and as side dishes.
The preparation is also known in Spain as huevo hilado ("spun egg"), in Japan as keiran somen (鶏卵素麺, "hen's egg noodle"), in Cambodia as vawee, in Malaysia as jala mas ("golden net"), and in Thailand as foi thong (ฝอยทอง; "golden strands").
History
Like other egg-based Portuguese sweets, fios de ovos is believed to have been created by Portuguese nuns around the 14th or 15th centuries. 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. The recipe was probably taken to Japan and Thailand by Portuguese explorers between the 16th and 18th centuries.
Uses
In Portugal and Brazil, fios-de-ovos are often used in fillings and decorations of cakes and other desserts, or as accompaniments for both sweet and savory dishes. They are often served with canned fruits alongside Christmas turkey in Brazil. In Japan, they are served in the form of dessert rolls (wagashi), and known as keiran sōmen (鶏卵素麺, egg yolk thin noodles).
