How to separate an egg
Making meringue or mayonnaise? You’ll need to separate your egg yolks from the whites.
The easiest way to do this is to use the simplest of tools, your hand. First, break the egg into a cup or small bowl. Hold one cupped hand over another bowl and tip the egg gently into your hand. Slightly separate your fingers so the white falls through and the yolk stays in your hand.
If you get a fragment of shell in your egg, use another piece of shell as a scoop to remove it.
