Eggs separate easily when cold.

1. Sharply tap the egg along its middle on the side of the bowl to make a crosswise crack and gently pull apart the two half over a bowl allowing some of the whites to fall away while keeping the yolk in one half of the shell.

2. Slowing transfer the yolk back and forth from one shell to the other being careful not to break the yolk, until all the whites have fall into the bowl. The smallest trace of yolk will keep the whites from foaming properly when beating. If any yolks get into the white it can sometimes be removed with the edge of the egg shell be sure to remove all the yolks.

3. Cover leftover unbroken egg yolks with cold water to prevent a skin from forming on its surface and refrigerate for up to two days and drain them before using. The egg whites can be store in the refrigerator for up to five days in a airtight container.
