You put eggs in a sauce pan, cover with water, turn on high. When boiling starts, continue to cook for 10 minutes.
Never use fresh eggs, use eggs that you've had about a week. If you have ever had hard boiled eggs that the shells refuse to come off, it's because they were boiled too fresh. Using eggs that are at least a week old will allow the shells to slide right off. And yes, week old eggs are still good if there are no cracks in the shell before you start. My mother always told me "at least 20 minutes", so 20 minutes is what I do.
Techniques I use to prevent cracking the shells when they boil, I usually use a pan just big enough to fit the eggs in one layer so they don't have much room to bounce around, line the bottom of the pan with a folded dish towel, fill with cold water and 'equalize' the temperature of the water and eggs before putting in the heat. By that I mean leaving the eggs sit in the water, say about an hour, until the eggs and the water are about the same temperature. I find trying to puncture the end too tedious. I often boil a whole dozen at a time without any cracked eggs.
Push a straight pin or a safety pin just through the shell on the round, not the pointed, end of each egg. This will allow air to escape while they boil and you will get perfectly shaped eggs. Put the eggs into a sauce pan, cover with cold water and boil gently until done, according to your own method of timing. I have a timer that goes into the water with the eggs and shows when they have reached a soft, medium or hard boil. Let the eggs cool completely before shelling. Gently crack the shell all around and peel the eggs under water to lessen the chance of pulling chunks of the white off with the shell. If the eggs are old, or over cooked, they may have a tough membrane between the shell and egg that must be gently pulled off with the shell, or that also can cause chunks of egg white to come off.
for hard boiled eggs, boil each egg 8 minutes
To boil eggs on a gas stove, you typically need to bring the water to a boil, then reduce the heat and let the eggs simmer for about 10-12 minutes for hard-boiled eggs.
boiled water
To boil eggs on an electric stove, you typically need to bring the water to a boil, then reduce the heat to low and let the eggs simmer for about 10-12 minutes for hard-boiled eggs.
you die them then you boil them
Yes if you hard-boil them first.
To hard boil 15 medium size hens eggs will take 10 minutes if you put them all in the same pan and boil them at the same time.
If you put then all into the same pan and boil them at the same time, then the answer is the same time as it takes to boil one egg. A hens egg for example would take 3 minutes to soft boil and 8 minutes to hard boil.
Shelled or not, eggs should be stored under refrigeration.
There is no reason not to refrigerate them immediately. When I boil eggs, I either eat them or refrigerate them for later consumption.
Sure you can...however do not expect to peel it easily. Fresh eggs are next to impossible to peel.
No, they will just get really hard, and taste terrible.
