There are multiple parts to the egg: the [[egg white]], the [[egg yolk]] and various thin membranes, Every part of the '''egg''' is edible, although the eggshell is usually thrown away. Eggs are a good source of [[protein]]. [[Roe]] and [[caviar]] are edible eggs produced by [[fish]]. They do not have an eggshell, since they hatch underwater. They also are much smaller and do not have a white or yolk. == Egg as a food ingredient == [[Bird]]s' '''eggs''' are a common [[food]] source. The most commonly used bird [[Egg (biology)|eggs]] are those from the [[chicken]], the [[duck]], and the [[goose]]. Smaller eggs such as [[quail eggs]] are sometimes used as a fancy ingredient, as are the largest bird eggs, from [[ostrich]]es. Most of the chicken eggs sold for human consumption are unfertilized. The hens are kept without any roosters. Fertile eggs can be bought and eaten as well. There is no difference in the food value of fertilised and unfertilised eggs. Fertile eggs for eating do not have a baby bird inside. This is because eggs have to be kept cool before they are sold, and the cold stops the young inside from starting to grow. Chicken eggs are widely used in many types of cooking. Recipes that use eggs include sweet and savoury dishes. Eggs can be used and cooked in many different ways. They can be hard-boiled, soft-boiled, scrambled, fried, combined with flour in cakes or eaten raw. Roasted eggs are used at the [[Jewish]] holiday of [[Passover]]. [[pickling|Pickled]] eggs are hard-boiled and then put in [[vinegar]]. They are often sold in UK [[Fish and chips|fish and chip shops]]. Eating raw eggs is not recommended for some people. Thi
