Checking Egg Quality & Freshness
If you are unsure of the age, place the egg in the shell in a bowl of water. A very fresh raw egg will sink in a bowl of water whereas an old egg will float. Break eggs into a cup to examine their quality before cooking or adding to a recipe. Once in a while, eggs may be spoiled (recognizable by an off odor) and should not be used. A fresh egg has a round, shapely, high-standing yolk surrounded by a thick, translucent white. As an egg ages, the yolk flattens out and the white becomes clear and runny.
