Quail eggs can be a bit more fiddly to peel and crack than chicken eggs.
How to crack quail eggs
The shell is thin, but the membrane just inside can be tough. If you simply try to crack the egg against the edge of a bowl, you may end up crushing much of the shell without the egg opening neatly.
I have developed my own technique where I tap it lightly on the counter, press a fingernail into the side and open it much like a regular egg. But if it is your first time, or you are a little unsure, you can use a small sharp knife to make a cut.
There are also special scissors for quail eggs. They clip off the top of the shell and can be handy if you are opening many eggs at once.
How to peel quail eggs
Many people say that peeling quail eggs is fiddly, and it may well be since they are so small. You will also notice here that the membrane is a little tougher.
Boiled eggs become easier to peel if you rinse them in cold water so they cool down. You can then tap it lightly on the table and roll it a little sideways with pressure, so that the shell crackles. Then you can use the tough membrane to your advantage and tear off much of the shell in one go. (A video is coming – it may help to see it in practice.)
