Explain five ways to test for the freshness of an egg

The Water Test. Place your egg in a tall glass of cold water. If it stays at the bottom, then it’s fresh.   The ‘Crack’ Test. Crack open your egg and see what the yolk and the white do. If the egg yolk bulges and the white is viscous and gathered tightly round the yolk, then the egg is still fresh.                                                                                         The Sloshing Test. If you shake the egg and there’s no sloshing noise from inside, then it’s fresh and can be eaten.   Pay attention to the ‘use by’ date. The packaging specifies a ‘use by’ date and the supplier guarantees that it will be usable at least until this date, provided that they are stored properly
