Also.. ever wonder how to tell how fresh your egg is?
How to tell how old a raw egg is while it is safely tucked away in its shell could seem a bit tricky, but not so. There is a simple test that tells you exactly how much air there is. All you do is place the egg in a tumbler of cold water: if it sinks to a completely horizontal position, it is very fresh; if it tilts up slightly or to a semi-horizontal position, it could be up to a week old; if it floats into a vertical position, then it is stale. The only reason this test would not work is if the egg had a hairline crack, which would allow more air in. That said, 99 per cent of the time the cook could do this simple test and know precisely how the egg will behave. In my opinion, all eggs should be used within two weeks if at all possible. An extra week is okay, but three weeks is the maximum keeping time.
I tend not to use an egg if it floats.....
