The most common egg consumed in most countries is the chicken egg. Its mild flavor and versatility has made it a staple in many households around the world. However, there are many types of edible eggs available -- from far more than just the humble chicken.
Similar in flavor to the chicken egg, turkey eggs are generally found in specialty markets. They are more often used for hatching than for eating. The nutritional value of turkey eggs is comparable to chicken eggs. One fresh 79 gram turkey egg has approximately 9 grams of total fat and a 63 gram fresh jumbo chicken egg has about 6 grams.
Duck eggs have a more pronounced flavor than chicken eggs, and they have a higher total fat content than chicken eggs. The white portion of duck eggs has more albumen (protein) than chicken eggs and has a rich density. Recipe Tips recommends using duck eggs for dessert recipes due to their "gelatinous properties."
Although they are not a staple of the American diet, quail eggs are becoming increasingly popular due to their reported health benefits. "Their nutritional value is three to four times higher than that of chicken eggs," says All Quails. Quail eggs also lack some of the negative qualities of the common chicken egg, such as tendency to cause food intolerance or allergies. One whole, fresh, raw quail egg contains roughly 5.8 milligrams of calcium, 4 milligrams omega-3 fatty acids, and more than 80 milligrams of omega-6 fatty acids.
It is unlikely that you will find an ostrich egg at your local supermarket; many specialty markets don't carry these large edibles either. One ostrich egg has the equivalent of roughly two dozen chicken eggs and can be cooked in the same manner as chicken eggs. Be prepared, however, for a long cooking time. According to the American Ostrich Association, it can take up to 90 minutes to hard-boil one ostrich egg.
The highly controversial gathering and eating of sea turtle eggs is illegal in many countries. However, in places like Costa Rica the eggs can be gathered legally and are a local delicacy. Their most avid customers are men, because turtle eggs are considered an aphrodisiac.
