The varying degrees of egg freshness determine what dishes they are best suited for. To test the freshness of an egg, place it in a bowl of water and watch - if it floats, the egg is not very fresh, but it doesn't mean it's ready for the compost bin just yet. The freshest eggs in the basket are great for poaching or frying, as the white won't separate. A few days on, eggs are good for boiling, as the white will separate more easily from the shell when peeling.A bit later, use your eggs for scrambling, frittatas or omelettes where the eggs can be combined with other ingredients. And lastly, the older eggs are perfect for baking.
If you're really concerned about the egg's freshness, do the nose test. Crack it into a bowl and sniff the contents - if it smells off, don't use it.
