Eu encontrei um bom recurso enquanto observava os ovos de pato. Vou deixar falar por si:
The higher protein in Duck Eggs means they mustn't be overcooked, or the whites will go tough and rubbery. Some people say they will be too tough if you completely fry them: they advise to rather partially fry them then add a few tablespoons of water to the pan, cover and let the steam moderate the heat and finish cooking them. Most people, though, seem to say they don't notice a difference between fried chicken and Duck Eggs.
Swapping Duck Eggs interchangeably in recipes for chicken eggs: some people say you can't; others who substitute all the time say nonsense, it's fine. When the Duck Egg whites are beaten they will come up a bit higher owing to the protein. They take a minute or so longer to start frothing up, but then make up for lost time.
