Are Eggs Good If They Sink

It is a widespread belief that an egg that sinks in water is fresh and of good quality, while an egg that floats is old and stale. However, this is not always the case. The freshness of an egg can be determined by several factors, including its age, storage conditions, and the presence of air inside the egg.

A fresh egg will typically sink in water because it contains a small air cell at its wider end. As the egg ages, the air cell gradually increases in size, causing the egg to become more buoyant. As a result, older eggs are more likely to float in water than fresh eggs.

However, there are some exceptions to this rule. For example, an egg that has been cracked or damaged may allow air to enter the egg, causing it to float even if it is fresh. Additionally, some eggs may naturally have a larger air cell than others, which can also cause them to float.

The best way to determine the freshness of an egg is to perform a float test. To do this, gently place the egg in a bowl of cold water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg stands upright in the bottom of the bowl, it is still good but may be a few weeks old. If the egg floats, it is likely old and should be discarded.

Another way to check the freshness of an egg is to look at its yolk. A fresh egg will have a firm, round yolk that stands up well when cracked open. As the egg ages, the yolk will become flatter and less firm.

It is important to note that the float test is not a perfect indicator of egg freshness. There are some eggs that may float but are still good to eat. If you are unsure about the freshness of an egg, it is best to err on the side of caution and discard it.

In general, eggs are a nutritious and versatile food that can be enjoyed in many different ways. By following the tips above, you can ensure that you are eating fresh, high-quality eggs every time.
