1. Start hot, finish cold. Carefully dropping an egg into a pot of boiling water instead of starting it in cold water is touted as the best route to easy-peel eggs. That’s because adding eggs directly to hot water helps them cook faster and keeps the egg whites from reaching too high a temperature.
Do hard-boiled eggs last longer peeled or unpeeled?

Why do hard-boiled eggs go black?
Our answer. The dark ring that forms around the yolk of a hard boiled egg is called a sulphur (sulfur) ring. When the egg is boiled the sulphur and hydrogen in the egg white combine to make sulphur dioxide gas, and this gas reacts with the iron in the yolk to form a dark ring.
Why is my hard boiled egg white gray?

Why you should not keep eggs in the fridge?
Experts believe that eggs are best stored at room temperature. Storing eggs in too cold a temperature, i.e. in the refrigerator can make them inedible.

Can you save soft boiled eggs?
Soft boiled eggs last for about 2 days refrigerated with the shell on. They don’t save as long as hard boiled eggs, since the yolk is not fully cooked. We’d recommend making these “to order” since they’re best warm. But if desired, you can save leftovers in the fridge.

Should hard-boiled eggs float?
Perform a Float Test
To perform the float test, gently set your egg into a bowl or bucket of water. If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air.

Is it safe to eat GREY eggs?
When eggs are boiled for long, the yolk becomes paler in color and eventually turns a greenish-gray.

While this might affect the texture and mouthfeel, it’s safe to eat.
Why is my egg white blue?
