It is not possible to do more precisely: The most reliable method of testing the freshness of chicken eggs

Tip:
Check the fuselage: In addition to the water test, check whether the hull is clean and free of cracks. There is a higher risk of infection in eggs with damaged shell.

Smell the last resort: if an egg floats, but you are not sure, beat the shell into a separate container. If it has an unpleasant smell, throw it away immediately.
Correctly stored: Store eggs chilled to prolong their freshness. Place them on the main shelf and not to the door as there the temperatures are more stable.

Use old eggs for specific recipes: While older eggs are not ideal for pan dishes or omelets, they are good for recipes where they are mixed with other ingredients, such as biscuits or cakes.
