How is it that you buy eggs from a shelf in the supermarket/shop, but on the box it says 'store in refrigerator once purchased'?? I don't store mine in a fridge, and haven't done for years as someone told me that the yolk is more likely to break the colder the egg is, is this correct?
Don't know about the yoke being more likely to break, but eggs basically stay fresh for longer if you refridgerate them.
With the quick turnaround a supermarket has, it's not worth their while putting eggs into refridgeration for a relatively short time (expensive to do) but they advise keeping them in a fridge once purchased. They are not like milk or butter that would curdle if not refridgerated constantly. Hope that makes sense and helps.
I never put eggs in the fridge ,I keep them in the larder. Mind you it is pretty cool in there.
If you boil or fry an egg straight from a fridge the yolk is likely to break .There is a scientific explanation for this but not being very scientifically minded it's basically the yolk expands in the shell when cold or something. Therefore you should always have eggs at room temperature before you use them.I always prick the eggs for boiling with an eggpick then they don't crack.
I don't think eggs should be stored in the fridge, despite what the supermarkets say. Yes, they should be kept cool, but not fridge temperatures.
I once worked for an egg processing company, and they stored eggs in an ordinary warehouse, sometimes for weeks (no, they weren't then sold as fresh!).
