Yolk

The yolk is the yellow center of an egg. It is only one cell. It is commonly seen in fried eggs. When it is mixed with the whites, it makes scrambled eggs. It is sometimes used in cooking. It is much higher in calories than the egg white. It has fat-soluble vitamins in it.^[1] Some eggs have two egg yolks in them.
