Pasture-raised Khaki Campbell duck eggs. Bigger yolks, harder shells, a little farm dirt. Great Falls, South Carolina.
Half-dozen pasture-raised Khaki Campbell duck eggs — about 1.5× a chicken egg, with deep orange yolks and the muddy fingerprints of the pond. Brush them off; don't wash them.
A duck egg is not a chicken egg's cousin. It's a different animal.
Our Khaki Campbells — a Welsh breed bred for laying — split their day between the pond, the pasture, and the duck house, in roughly that order. They don't have a chicken's tidy sense of where to lay. You'll find duck eggs at the bottom of a puddle, in the mud at the edge of the run, half-buried in a corner of the duck house. By the time we collect them they look like they've had a hard week. They have. Brush off the worst of it; the shell is thicker than a chicken's and the bloom seals the inside.
What you get for the trouble: a larger egg, by 30 to 40 percent. A yolk that's deeper orange and proportionally bigger. More protein, more fat. Thicker shells that last six to eight weeks in the fridge without losing a thing.
Bakers know about duck eggs. The extra fat and protein is why a pound cake made with duck eggs rises higher and cuts cleaner. Pasta dough is a little springier. Custards are richer. If you've ever wondered why old-country bakers swore by duck eggs, do one batch of cookies with them and you'll find out.
Some people who can't tolerate chicken eggs — minor allergies, mild sensitivity — can eat duck eggs without trouble. Different protein structure. (Not medical advice. If you have a real egg allergy, see a real doctor.)
Counter for two weeks if you don't mind looking at the dirt. Fridge for six to eight weeks. Don't wash until you're about to cook — water dissolves the bloom and the egg starts ageing fast.
Crack on a flat surface and pull, don't tap on the rim of a bowl: the thicker shell shatters into the egg if you crack it on an edge.
For baking: 1 duck egg ≈ 1.5 chicken eggs. Or use weight: 60g of duck egg ≈ 1 large chicken egg's worth.
For frying: a little less heat than you'd use for a chicken egg, and a little more time. The whites are firmer and need it.
