Making salted duck eggs at home requires just salt, water, and patience. The process is simple: submerge duck eggs in a strong brine (or coat them in salt) and wait three to six weeks while the salt slowly penetrates the shell, transforms the white into a translucent, briny layer, and turns the yolk into a firm, deeply orange orb that oozes oil when cooked. There are two main methods, and both work well with minimal equipment.
Why Duck Eggs Work Best
Duck eggs have larger, more porous shells than chicken eggs, which allows salt to penetrate more efficiently and produces a richer, more savory result. They’re also fattier: about 14 grams of fat per egg compared to roughly 11.5 grams in a chicken egg. That extra fat is what gives salted duck egg yolks their prized oily, golden quality. You can salt chicken eggs using the same techniques, but the yolks won’t develop the same richness or deep color.
The Wet Brine Method
This is the easiest and most popular approach. You’ll need a clean glass jar or food-safe container, water, and salt (coarse sea salt or kosher salt both work well).
The standard ratio is about 1 cup of salt to 3 or 4 cups of water, depending on how salty you want the finished eggs. A 1:4 ratio (one part salt to four parts water) gives a milder result, while 1:3 produces a more intensely salty egg. Bring the water to a boil, stir in the salt until fully dissolved, then let the brine cool completely before using it.
Place your duck eggs gently into the jar and pour the cooled brine over them. The eggs need to stay fully submerged, so if any float, weigh them down with a small plate or a sealed bag filled with extra brine. Seal the container and store it in a cool spot out of direct sunlight. Room temperature is fine and actually speeds the process slightly compared to refrigeration.
The Dry Salt Method
Dry curing skips the brine and coats each egg directly in salt. The traditional version, still common in the Philippines and parts of China, uses a paste made from salt mixed with clay, charcoal, or ash. A classic Filipino “Pateros style” recipe combines clay, table salt, and water in a 1:1:2 ratio, creating a thick paste like cake batter that gets packed around each egg. In Asian markets, you’ll sometimes see salted eggs sold coated in a thick black layer of salted charcoal paste, which is this same method.
A simpler home version works just as well. Dip each egg briefly in a clear spirit like rice wine or vodka (this sanitizes the shell and helps salt adhere), then roll the egg in coarse salt until it’s evenly coated. Pack the coated eggs into a jar, stacking them carefully, then seal the jar and store it in a cool, dry place. Dry-cured eggs generally need longer than brined ones: five to seven weeks for the best results.
How Long to Cure
Timing depends on your method and how salty you like them. For the wet brine method, 21 days is the minimum for a noticeable cure. At this point the white will be salty, but the yolk may still be soft. For a firm, deeply cured yolk with that characteristic oily quality, 30 days is better, and duck eggs benefit from going even longer, up to six to eight weeks. The longer they sit, the firmer and oilier the yolk becomes.
For the dry salt method, plan on at least five weeks, with six to seven weeks being ideal. The paste or salt coating slows the penetration compared to a liquid brine, so the extra time is necessary.
If you want more or less saltiness, adjust the duration rather than drastically changing the salt ratio. A few extra days beyond the minimum can make a significant difference.
What Happens Inside the Egg
Salt passes through the porous shell and gradually dehydrates the egg’s contents. The white absorbs salt first and becomes very salty and slightly translucent. The yolk takes longer to cure, but as salt concentrates inside it, something interesting happens: the fat-carrying proteins in the yolk lose their ability to hold fat in suspension. The fats separate out and fill the tiny gaps between solidifying yolk particles. This is what creates the gritty, sandy texture and the orange oil that seeps out when you cut into a cooked salted egg yolk. Cooking accelerates this release, which is why a boiled salted egg yolk appears to “sweat” oil.
Testing for Doneness
After about 10 days of brining, you can pull one egg out as a test. Boil it for 12 to 15 minutes (just like a hard-boiled egg), let it cool, then peel and cut it in half. At this early stage, the white should taste noticeably salty, but the yolk will likely still be soft and only lightly cured. This is normal. You’re checking for progress, not a finished product.
A properly cured egg, tested at 30 days or later, will have a yolk that holds its shape when you pick it up with your fingers. The color should be a deep orange, and when sliced, you should see a slightly granular texture. If the yolk looks pale or feels mushy, give the remaining eggs another week. For the oiliest, most vibrant yolks, duck eggs cured for six to eight weeks are noticeably superior to those pulled at three or four weeks.
Cooking and Storing Finished Eggs
Once the eggs reach the saltiness you want, remove them from the brine (or wash off the salt coating) and store them in the refrigerator. This slows the curing process so they don’t become overwhelmingly salty. Properly cured salted duck eggs keep in the fridge for several weeks.
The most common way to cook them is simply boiling. Place the eggs in a pot, cover with cold water, bring to a boil, then cook for 12 to 15 minutes. The white will be firm and very salty, while the yolk will be dense, grainy, and rich. Many people eat the yolk on its own with congee or rice, since the white can be intensely salty by itself.
Salted egg yolks are also used as an ingredient: crumbled over stir-fried vegetables, mixed into mooncake fillings, or tossed with prawns in the popular salted egg yolk sauce found at many Southeast Asian restaurants. The yolks can be separated raw from uncured whites (carefully, since the yolk is firm enough to handle) and baked at a low temperature until they’re glossy and slightly translucent, which concentrates their flavor even further.
