With an egg separator you can easily separate egg white and yolk.
It is made of tin or plastic, round (approx. 6-10 cm), with holes or slots at the bottom and possibly with a handle. When the separator is placed over a bowl and the egg is broken above it, the yolk remains in the small recess in the bottom while the egg white drips through the openings in the bowl.
The yolk separator can also be made of stone. It then consists of a tray with a slot that fits on a receptacle. The dish and container thus form one whole. [MOT]
