prompter: How can you differentiate between a cooked and raw egg?

assistant: Assuming both the cooked and raw egg are still in their shell. One method to determine the difference between a cooked egg and a raw egg is to place them on a surface and spin them. 

The fluid inside the raw egg will cause that egg to wobble. Whereas the cooked egg is solid and won’t wobble. The raw egg should also spin slower and if you stop the spinning with your finger and then take your finger away, it will continue to move for a few more seconds because the fluid inside is still moving.

prompter: Are raw eggs healthier than cooked eggs?

assistant: There is no simple answer to whether raw eggs are healthier than cooked eggs as it depends on the context and the individual's needs. While raw eggs are a good source of protein and contain essential nutrients like vitamins and minerals, there are potential health risks associated with consuming raw eggs.

Raw eggs can be contaminated with bacteria such as Salmonella, which can cause food poisoning. Cooking eggs to a minimum temperature of 160°F/71°C can kill harmful bacteria, making cooked eggs safer to eat than raw eggs.

On the other hand, some people believe that raw eggs have health benefits that are lost during cooking, such as preserving the amino acids and enzymes in the egg. However, there is little scientific evidence to support these claims, and consuming raw eggs comes with the risk of infection.

In general, if you are concerned about the potential risks of consuming raw eggs, it is advisable to cook them thoroughly to reduce the risk of foodborne illness. However, if you choose to consume raw eggs, it is recommended to choose high-quality, fresh eggs from a reputable source and handle them properly to minimize the risk of contamination.

assistant: No, drinking or eating raw eggs offers no major advantages over eating poached or boiled eggs. 
Despite raw eggs containing slightly more nutrients, the nutrients in cooked eggs are in fact easier for your body to digest and absorb.

assistant: A cooked egg has a firm white and a solid yolk, while a raw egg has a runny white and a yolk that moves freely inside the shell. Additionally, a cooked egg will usually have a different texture and color compared to a raw egg.

prompter: I mean how can I differentiate them without needing to break them.

assistant: Easiest Method  : Spinning the Egg

Grasp the egg between the fingers and thumb of your hand. With a sharp twisting motion, spin the egg on its side like a top. The motion you use should be a little like snapping your fingers. It should now be spinning at a steady, regular pace.

Some flat surfaces in your kitchen that you can use are a cutting board, a counter top, or even the bottom of the sink.

2. Stop its rotation quickly.

Extend your index finger as if you were pointing. Quickly place your finger down on the center of the rotating egg. It should stop spinning. Immediately remove your finger from the egg as soon as it comes to a stop.

Press hard enough to stop the motion of the egg quickly. It should go from spinning to still in the span of a second or so.

3. Watch what happens to the egg.

Depending on whether your egg is hard boiled or raw, it will behave differently at this point. See below:

If the egg stays still, it is a hard boiled egg.

If the egg continues to slowly rotate or wobble it is uncooked. This is because the liquid white and yolk are still spinning inside the shell. The egg's center of gravity shifts as the liquid contents move around, causing the egg to keep moving.

4. For a quicker test, watch the egg's motion as it spins.

The test above should tell you accurately whether or not your egg is hard boiled. However, you can also get this information by carefully watching the way the egg spins — you don't need to stop it with your finger. This is convenient if you need to test many eggs at once.

If the egg spins quickly and steadily like a top, the egg is hard boiled. Its center of gravity is stable.

If it spins slowly, it has a major wobble, or it's tough to spin at all, it's raw. The liquid inside is shifting around as the egg spins and throwing it off balance.

Other Methods :
1. Shake the egg.

2. Look for tiny streams of air bubbles.

Place the egg in a pot or bowl of very hot water (nearly boiling is best). Look for small streams of bubbles coming out of the shell of the egg. When the test is over, take the eggs out quickly unless you want them to boil.

If the egg is raw, you will see these bubbles. Egg shells are not completely solid — they are actually covered by thousands of tiny holes that sometimes can allow gases to pass through. Heating the egg makes the gas inside the shell to expand and pass through these holes, creating bubbles.

If the egg is boiled, you probably won't see these bubbles because the gas was already forced out during the boiling process.

3. Shine a flashlight through the egg.

Wait until night or head to a dark room with your egg and a bright flashlight. Turn the flashlight on and hold it against the side of the egg. This test works best with smaller flashlights so that the rim of the flashlight forms a tight "seal" against the egg shell.

If the egg lights up like a lantern, it is raw. The liquid inside allows the light through.

If the egg is dark and opaque, it is hard-boiled. The solid white and yolk do not let the light through.

assistant: A trick to figure out if the egg is cooked or not is spin the egg, stopping its spin and letting go. If the egg stops spinning after letting go it is cooked, if it still spins afterwards then it is still raw. This occurs because an egg that is raw have momentum even after the shell is stop from because the liquid egg inside can spin freely.

prompter: That's a cool trick, and I will try it.  But are there other good methods of determining this?

assistant: A hard boiled egg will spin nicely and a raw egg will wobble. The raw egg is full of fluid which moves around as it spins making the egg wobble.

prompter: If the center of the egg is mostly but still not fully cooked, is it safe to eat?
