Convert chicken eggs to duck eggs
The calculator matches total shelled-egg weight. Weigh your duck eggs without shells for the most useful result.
Target egg weight: 100 gThat is about 1.43 of your measured duck eggs.
Practical method: crack, whisk and weigh 100 g. Save the remainder for another use and refrigerate promptly.
Cakes benefit from weighing the egg because extra liquid and protein can change crumb and rise.
