Bird and fish eggs are common food sources. For fish eggs, see roe or caviar. Reptile eggs, particularly turtle eggs, are sometimes eaten as well. Chicken eggs are standard. Duck, goose, quail, and ostrich eggs are occasionally used as gourmet ingredients.

Eggs are frequently used to bind other ingredients together, trap air in the food, or create an emulsion. Sometimes the whole egg is cooked together. Sometimes the egg yolk is used separately from the egg white. In most recipes, a whole egg may be replaced with two egg whites to make a tastier and more healthful dish.

Egg sizes

The "USDA Large" egg is about the same as the "EU size M" egg. (both being the standard choice in the appropriate locations) So, for normal recipes, it is best to avoid specifying egg size. USDA eggs are specified as the minimum weight of a dozen. EU eggs are specified as per-egg weight ranges, plus a per-100 minimum. 

EU weight standard

SIZE             PER-EGG        PER-100-MIN
XL-very large    73 g and more   7.3 kg
L-large          63 to 73        6.4
M-medium         53 to 63        5.4
S-small          under 53 g      4.5

USDA weight standard

CLASS         MIN NET / DOZEN   CONVERTED TO MIN GRAM/EGG
Jumbo         30 ounces         70.75
Extra Large   27 ounces         63.675

Rotting and disease

Eggs may also be pickled, hard-boiled and refrigerated, or eaten raw, though the latter is not recommended for people who may be susceptible to salmonella, such as the old, the infirm or pregnant women.

When eggs become rotten, the yolk will turn green and the egg will emit a sulphurous smell when broken. Although deemed offensive by most Western palates, fermented eggs are considered a delicacy by some in China, when prepared using a special method which includes letting them sit for three months to age (or rot, depending on one's interpretation).

Raw eggs may carry salmonella bacteria contaminations, and should be avoided by those with weak or undeveloped immune system. The bacteria will be killed in fully cooked eggs, which may be considered safe.
