Salted Duck Eggs
Also known as: Xian Ya Dan, Salted Eggs, Muoi Trung Vit, Itlog na Maalat
Salted duck eggs are duck eggs cured in a brine of salt and water for 30–60 days, resulting in a firm, salty white and a dramatically changed yolk — dense, grainy, deeply orange, intensely flavored, and rich with an oily quality.
The yolk, not the white, is the prize: it appears in mooncakes, lotus paste buns, and is the star of the modern "salted egg yolk" craze that swept Asian food culture. A properly cured salted duck egg yolk is one of the most concentrated and distinctive flavors in the Chinese pantry.

Traditional Medicine Perspectives
Traditional Chinese Medicine
Salted duck eggs are classified as cool and salty in TCM, associated with the Heart, Lung, and Kidney meridians. Duck eggs are considered cooler and more Yin-nourishing than chicken eggs. They are used to clear heat, nourish Yin, moisten the Lung, and calm the Heart. The salt content means they should be eaten in moderation.
Modern Scientific Research
Salted duck eggs retain the high nutritional value of fresh duck eggs — rich in protein, fat-soluble vitamins (A, D, E), choline, and minerals. Duck eggs have higher fat content than chicken eggs, which contributes to the yolk's characteristic richness.
The vivid orange color of salted duck egg yolks reflects high carotenoid content (zeaxanthin and lutein), beneficial for eye health.
Cultural History
Salted eggs have been produced in China for over two thousand years, with the technique spreading throughout Southeast Asia via Chinese diaspora communities.
They are particularly associated with the Mid-Autumn Festival, where salted egg yolks embedded in lotus paste mooncakes symbolize the full moon. In the Philippines, red-dyed salted duck eggs (itlog na maalat) are a beloved condiment.
The modern explosion of "salted egg yolk" as a flavor in chips, pastries, and sauces reflects the universal appeal of the yolk's rich, sandy, umami-laden quality.
Culinary Uses
Use yolks in mooncake filling — steam them first for a crumbly, sandy result. Make salted egg yolk sauce by pan-frying mashed yolks in butter with curry leaves and chili until foamy.
Use as a filling in Chinese steamed buns. Slice and serve alongside congee. Add crumbled yolk to fried rice.
Preparation Methods
Raw salted eggs should be boiled or steamed for 10–12 minutes before consuming the white, or the yolks can be separated raw for baking and sauce applications.
For steaming: place in a steamer for 15–20 minutes.
