Some grocery stores and farmers' markets sell eggs with blue shells. Do they taste different from regular white or brown eggs?
To see if blue-shelled eggs tasted different, we made three batches of scrambled eggs—one with only blue-shelled eggs, one with only brown-shelled eggs, and one with only white-shelled eggs—and tasted them side by side.
Overall, tasters didn't notice flavor differences among the scrambled egg samples. The only notable differences were visual: The blue-shelled eggs had yolks that were smaller and more orange, so they produced yellower scrambled eggs. The blue-shelled eggs we bought cost about three times as much as regular brown- or white-shelled eggs.
The Bottom Line: The color of an egg's shell is not indicative of the egg's flavor; the flavor of eggs is mostly dependent on freshness and the chicken's diet, while shell color is typically determined by the bird's breed.
