Duck Egg Mayonnaise Recipe: Rich, Silky and Safe

Duck egg mayonnaise is a thick, creamy emulsion of duck egg yolks, oil, mustard, and bright lemon juice, made here with a gently heated yolk base. Its rich flavor is lovely in sandwiches, salads, and dips, and the cooked-yolk method gives you a practical way to make it without relying on raw eggs.

Ingredients

2 large duck egg yolks, about 1.8 oz (50 g)
1 cup neutral oil, such as canola, sunflower, or light olive oil, 8 fl oz (240 ml/about 220 g)
1 teaspoon Dijon mustard, 0.18 oz (5 g)
2 teaspoons fresh lemon juice, 0.34 fl oz (10 ml)
1 teaspoon white wine vinegar or cider vinegar, 0.17 fl oz (5 ml)
1 tablespoon water, 0.5 fl oz (15 ml), plus up to 2 teaspoons (10 ml) to adjust the texture
½ teaspoon fine salt, about 0.1 oz (3 g), or to taste
⅛ teaspoon white pepper, about 0.01 oz (0.3 g), optional

Instructions

Set up the ingredients and equipment. Allow about 5 minutes to separate the duck eggs and measure everything. Put the yolks, mustard, lemon juice, vinegar, and 1 tablespoon water in a heatproof bowl that will sit securely over a saucepan. Have a whisk, an instant-read thermometer, and a second bowl ready for cooling. Keep the oil measured and within reach so you can add it steadily later.
Gently heat the yolk mixture. Add a few inches of water to the saucepan and bring it to a gentle simmer; the bowl should sit above the water rather than touch it. Set the bowl over the pan and whisk continuously, scraping around the sides and bottom. Heat until the mixture reaches 160°F (71°C) on a food thermometer. The USDA FSIS safe minimum for egg dishes is 160°F (71°C); check the yolk mixture itself, not the bowl, and keep whisking so it warms evenly. This usually takes about 6 minutes, though the pan and bowl can affect the timing. The mixture should look slightly thicker and foamy. If you see small cooked flecks, take it off the heat and whisk briskly; strain the base if needed.
Cool the base promptly. Transfer the bowl off the saucepan and set it over a larger bowl of ice water, taking care not to let water get into the yolks. Whisk occasionally for 15 minutes, until the mixture is cool to the touch. Cooling before adding oil helps protect the emulsion and prevents the oil from becoming warm and loose. Do not leave the cooked egg mixture sitting out while you do other tasks.
Start the emulsion. Transfer the cooled yolk base to a food processor, blender, or a tall narrow container if using an immersion blender. Blend briefly to make it smooth. With the machine running, add the oil drop by drop for the first few tablespoons. Once the mixture looks glossy and begins to thicken, continue adding the oil in a very thin, steady stream. This gradual start is the key to getting oil droplets dispersed through the yolk rather than ending up with a greasy layer.
Finish and adjust. When all the oil is incorporated, blend in the salt and optional white pepper. Taste with a clean spoon. Add a little more lemon juice or vinegar for a sharper finish, or blend in up to 2 teaspoons water if the mayonnaise is too thick. The finished texture should be creamy and spoonable; it will firm slightly after chilling. Scrape it into a clean container and refrigerate promptly.

Tips

Choose a mild oil. Canola, sunflower, and other neutral oils let the duck yolk flavor come through. Extra-virgin olive oil can taste bitter when blended vigorously and may overpower the sauce. If you want olive flavor, replace up to ¼ cup (60 ml) of the neutral oil with a mild olive oil rather than using all strongly flavored oil.
Add the oil slowly at first. The first few tablespoons are where an emulsion is most likely to fail. If the oil is poured in too fast, pause, blend the mixture until smooth, then resume in a thinner stream. A food processor makes a steady pour easier, while an immersion blender works best in a container only slightly wider than its head.
Use a thermometer and whisk constantly. The yolks need to reach 160°F (71°C), but direct high heat can scramble them before the whole mixture reaches the target. A gentle simmer under the bowl and continuous whisking provide better control. If the base develops a few lumps, strain it before blending in the oil.
Keep every tool clean and dry. Use a clean bowl, blender attachment, and storage container, and avoid returning a tasting spoon to the mayonnaise. Duck eggs can be larger than chicken eggs, so weigh the yolks if they are unusually small or large; around 50 g total keeps the balance close to the recipe.

Serving Suggestions

Use this mayonnaise anywhere you would use a classic mayonnaise, allowing its fuller yolk flavor to be part of the dish. Spread it on a ham, turkey, or tomato sandwich, use a thin layer in a chicken salad, or serve a spoonful alongside cold poached fish or crisp vegetables. It is also a good base for potato salad and egg salad; fold it through gently so the dressing coats the ingredients without turning them into a paste.

For a quick dip, stir a few tablespoons into finely chopped herbs, a little grated garlic, and a squeeze of lemon. A spoonful makes a rich dressing when thinned with water and extra vinegar, or it can be spread beneath sliced tomatoes on toast. Because the flavor is more substantial than many store-bought mayonnaise-style sauces, start with a little less than you think you need, then add more to taste.

Variations

Garlic mayonnaise: Blend in one small finely grated garlic clove after the oil has emulsified. Let it stand in the refrigerator for about 20 minutes before serving so the garlic flavor can settle into the sauce. Keep the same storage limit as the base recipe.

Herb mayonnaise: Stir in 1 tablespoon (about 4 g) finely chopped parsley, chives, or tarragon. Soft herbs give a fresh finish; add them just before serving for the brightest color. A mix of parsley and chives is especially versatile with sandwiches and boiled potatoes.

Spicy mayonnaise: Mix in 1 to 2 teaspoons (5 to 10 g) of hot sauce, or a pinch of cayenne. Add a small amount first and taste before adding more, since the sauce can become noticeably hotter as it sits.

Mustard-forward version: Increase the Dijon mustard to 2 teaspoons (10 g) for a sharper, more savory mayonnaise. For a milder taste, replace it with 1 teaspoon (5 g) of smooth yellow mustard; the color and flavor will be a little softer.

Acid adjustment: Lemon juice gives a bright citrus edge, while vinegar tastes cleaner and more direct. You can replace the lemon juice with an equal amount of vinegar, or use 1 teaspoon (5 ml) of each for a balanced tang. Change the acid in small increments so the sauce does not become too sharp.

Storage and Reheating

Transfer the mayonnaise to a clean, covered container and refrigerate it within 2 hours of making it. Keep it at 40°F (4°C) or colder and use it within 3 days. The recipe contains egg, so do not leave it at room temperature for serving longer than 2 hours; if the room is hotter than 90°F (32°C), limit that time to 1 hour. For a buffet or picnic, set the serving bowl over ice and return the main container to the refrigerator between servings.

This sauce is not suitable for room-temperature storage or home canning. Freezing is not recommended because thawing commonly separates the emulsion and leaves a watery or grainy texture. Mayonnaise is served cold, so it does not need reheating; do not heat it as a way to extend its storage life. Discard it if it has been held too warm or you are unsure how long it has been out.

Frequently Asked Questions

Does duck egg mayonnaise taste different from chicken egg mayonnaise?
Yes, it is usually richer and more full-bodied because duck yolks are relatively large and rich. The mustard and lemon keep that richness balanced. The difference is noticeable but not so strong that it will clash with ordinary sandwich or salad ingredients.

Can I make this with raw duck egg yolks instead?
This recipe heats the yolks to 160°F (71°C) for food safety, so raw yolks are not needed. Do not assume lemon juice or vinegar makes raw eggs safe. If you choose another recipe that uses uncooked egg, use commercially pasteurized eggs and follow the product directions; pasteurized duck eggs may be difficult to find, so check the labeling rather than relying on appearance.

Why did my mayonnaise stay thin?
The oil may have gone in too quickly, or the yolk base may not have been fully cooled before blending. Stop adding oil and blend the mixture until smooth. If it still looks separated, put 1 teaspoon (5 ml) cool water in a clean container and slowly blend the thin mixture into it. Add the mixture gradually; this can help form a fresh emulsion.

Can I use a hand whisk instead of a blender?
Yes. Use a sturdy whisk and a bowl set on a damp towel so it does not slide. After the cooked yolk base has cooled, whisk in the oil a few drops at a time at first, then in a very thin stream as the sauce thickens. It takes more effort than using a machine, but the method is the same.

Can I substitute chicken egg yolks?
Yes. Use 2 large chicken yolks, about 36 g total, and follow the same heating and emulsifying steps. The yield may be slightly less rich, and the mayonnaise may be a little less thick. Keep the same oil quantity to start, then adjust the texture with a teaspoon of water if needed.

How can I tell if the mayonnaise has gone bad?
Time and temperature are more reliable than smell or appearance alone. Follow the 3-day refrigerated limit, and discard it if it was left out beyond the safe serving window, has been contaminated by used utensils, or you cannot confirm its storage history. Do not taste it to decide whether it is safe.
