Preserved duck eggs, also known as century or thousand year old egg, is a traditional preserved food created before the advent of modern refrigeration. Fresh duck eggs are cured using a proprietary clay mixture that transforms the egg whites into a transparent black jelly with a turquoise green yolk. Century eggs have a strong and pungent flavor reminiscent of brie or strong cheese with equally concentrated umami.
Uses: Preserved duck eggs are commonly eaten with plain foods such as white rice or congee. Add soy sauce, sesame oil, and scallion to enhance the flavor of these umami rich eggs.
