'egg threads') is a traditional Portuguese sweet food made out of egg yolks, drawn into thin strands and boiled in sugar syrup.

In Seville, it is shaped into peaked cones called yemas de San Leandro [es].

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.

It can be bought only in a few select shops in Phnom Penh, where it is made by women who used to live in the Royal Palace.

In Laos, it is traditionally served at weddings and other ceremonial occasions, where the length of the egg threads symbolises long life.

In Brazil, they are also used as accompaniments in savory dishes, often served with canned fruits alongside Christmas turkey.

[14][15][better source needed] In Japan, they are served in the form of dessert rolls (wagashi),[16] and known as keiran sōmen (鶏卵素麺, egg yolk thin noodles).
