Determining egg freshness is crucial for both quality and safety in the kitchen. A simple test can quickly reveal whether an egg is still good to use before cooking. The method involves placing the egg in a bowl of water; if it sinks and lays flat, it's very fresh. An egg that sinks but stands on one end is still good, but should be used soon. If the egg floats, it's likely spoiled and should be discarded. This quick check helps avoid unpleasant surprises and potential foodborne illness. Using fresh eggs ensures better baking results and a more enjoyable culinary experience.
