Trứng Vịt Muối – Preserved Duck Eggs in Tea

These are duck (or can be chicken) eggs that preserved for at least 100 days in a clay-like mixture of red earth, garden lime, salt, wood ash, and tea and wrapped in rice husks. In the process, the egg yolk becomes dark green or gray and assumes a sulfuric smell, while the white turns into brown jelly.
