Soft Boiled Eggs

My favorite way of preparing eggs is to fry them over medium. But sometimes, I like to switch it up a bit and boiling them in their shell until soft is my favorite way to do that. It's faster than boiling them hard, and (since I don't much like solid yolks) it's tastier. Here's how I do it.

This recipe assumes the eggs have been refrigerated and have just been removed from the refrigerator before beginning.

Boiling eggs in the shell pretty much starts the same way - by bringing water to a boil. The amount of water is variable depending on the size of pot and the number of eggs being boiled. An easy way to determine how much water is needed is by placing the eggs into the pot selected and pouring water in until there is at least 1 inch (more than 2 cm) of water covering the eggs.

You really need only about 1/2-in. (more than a cm) of water above the eggs for this to work well, but I find that some amount of water will escape as vapor while it is boiling and waiting for eggs to be deposited. Depending on how often you check on the pot, water loss can be substantial, so try to make sure you have at least an inch of water over the eggs before you start.

Remove the eggs from the water and place the pot (with its lid on) onto the burner on medium-high to bring to a boil. The water is ready once it reaches a rolling boil (large bubbles rising cause the surface of the water to tumble and roll).


In the original article I wrote, the eggs were placed into the water and boiled for 5 minutes before being shocked in ice water. After more testing with another couple dozen eggs, I'm now advocating the following method:

Once the water is boiling, place refrigerated large eggs into the boiling water, cover, and remove the pot from the heat. Allow the eggs to steep in the nearly boiling water for seven minutes.

As soon as seven minutes are up, remove the eggs and place into an ice water bath. This will chill the exterior of the egg serving two purposes. When rapidly cooked, eggs, like most dense foods, do not heat evenly. The outside portions of the egg (the egg whites) are much hotter than the interior (the egg yolk). By shocking the shell with ice water, we lower the temperature of the egg whites to a temperature below that of the egg yolk and this causes the egg yolk to stop cooking. Otherwise, the yolk would continue to draw heat from the whites and raise its temperature while the egg white temperature lowered resulting in overcooked egg yolks.

The other reason for shocking the eggs is that it causes a little bit of shrinkage in the egg, hopefully making it easier to peel.


After about 1 minute, peel the eggs. I find it easiest to do this by tapping the egg lightly (just enough to crack the shell) all over starting with the fat end (I start here because there's an air pocket and I feel more comfortable using a little more force to break the shell without damaging the egg). I then run a thin stream of cold water to help pull away the shell and membrane as I carefully peel the egg. Be careful, it's not as hardy as a hard boiled egg due to the liquid core.


If the soft boiled eggs are too cold after you're done peeling them, you can submerge then into the cooking liquid (which should be just around simmering at this point in time) to reheat. About two to three minutes will bring it back up to temperature.


Served with a light sprinkling of kosher salt, a soft boiled egg makes a great addition to breakfast or a pleasant surprise accompanying your dinner entree.?}?>



If this is your first time using this recipe, I suggest cooking one or two eggs with this method first. Breaking into the egg, you should find the whites almost fully cooked (solid) with the yellow yolk thickened and viscous.

Note: For individuals with a poor immune system, the young, or the elderly, it is not advisable to consume soft boiled eggs or undercooked yolks.

That's interesting, my cooking method for soft boiled eggs is, after adding eggs to boiling water: boil for 1 minute, take off the heat and cover pan for 4 minutes. The rest of the "recipe" is the same, except I usually serve them in the shell in an egg cup, not peeled.

I would have thought that 5 minutes at a boil would mean they were overcooked.

Might have to try it some time for comparison!

Are you kidding me? Such a waste of effort, just guess about the water height, but most importantly you DO NOT need at least an inch of water above the eggs. I just made some perfect hard boiled eggs tonight with water that didn't even quite cover the eggs. I make soft-boiled eggs all the time the same way.

The only reason I can think of for putting a lot of water, is the same reason you want a lot of water when boiling pasta: so that the water doesn't cool down a lot when you add the room temperature/fridge temperature eggs/pasta to the water. But if you're doing one egg, having extra water in the pot won't make a huge difference. Secondly, if you have less water, even though the water may cool down a bit, it will heat up fast anyways when you are doing the keep-the-pot-on-the-element method.

I am also a bit surprised that they the yolks are not solid after 5 minutes. I usually go for 4 and any longer makes the yolks solid. Probably depends on the size of the eggs. Are you using small eggs?

I love a nice soft-boiled egg, but usually end up scrambling instead because I can never seem to get the boiling right. I guess the ice bath is the key! Thanks much. I'll try this tomorrow.

Subject: Tea Eggs
First of all, nice to have you back, Michael, it's been awhile since I've seen a post from you and I've missed it!
This is kind of straying from topic, but I tried making tea eggs recently and I really like them.
These eggs are hard boiled all the way, then the shell is cracked but not peeled. Then you steep the eggs in tea in the fridge for a day or too. If you do it right, the egg gets a pretty cracked shell pattern, and the tea gives the egg a nice complimentary flavor.
Most of the ones I have made I cracked the shell too finely, and the tea seeped in and just colored the entire egg. Still tasted good, but not something I would serve at a party.
I think the secret it to tap the egg with a butter knife instead of rolling it, and using really strong tea to steep in.
Next, deviled tea eggs...I'm sure I will come up with some really horrendous combinations in the beginning...scallions, ginger, something that colors the egg yolk to compliment the marblized white...add texture...truffles...ham...beans...hash...hmmmm, not all together though

I'm retesting the cooking method with a couple different pots as we speak. I'll probably update the recipe with a non-boiling recipe once I'm done with my tests. Stay tuned.

I finished running another set of soft boiled egg tests and updated the article to use the boil water and remove from heat method which should result in fewer cracked egg shells. The recipe produces a soft boiled egg that is peelable and has solid whites with a viscous and flowing yolk. I'll be posting an article soon with the various stages of soft boiled eggs for those who want looser whites or a more solid yolk.

a very old trick to minimize cracking is to pierce the big end of the egg. that lets the air sack expand and minimizes internal pressure.

there are purpose made "egg piercers" - I have used an ice pick in a pinch.

Subject: Another Method
I use a hot pot for this. I put the egg in with the water tepid, and usually let it sit for a while to warm up a bit. Then I plug in the pot and let it come up to just starting to boil, unplug and cover it, and let it sit for four minutes. I quench the egg under cold tap water and shell immediately. Since I generally scoop out the egg into a bowl, continued cooking of the yolk is not an issue.

I use a needle and make a small hole in the big end. The eggs never ctack.

Gday from a fellow Engineer in NZ. Just made the boiled eggs and my wife declared them the best she had ever had. The idea of peeling them is amazing - great stuff!

My own technique is rather different. Instead of throwing the eggs in boiling water, with the risk of cracking them due to the temperature shock, I put them in cold tap water which I then bring to the boil. It takes some experimentation to figure out how long you then need to put them on the fire, but it works and it works quite reliably. For soft yolks, in my case (at sea level, ymmv) 8 minutes does it. For semi-soft yolks, 10 minutes is what you want.c

i agree with an above comment. if cooking just 2-3 eggs, i don't really bother covering the eggs completely with water. Mine usually goes up to only half or a little over half the eggs. bring water to a boil, turn off heat, put in eggs and cover. i usually take out mine after 6 minutes, if the eggs came from the fridge. i love them a little runnier. 10 minutes to hard-cook it.

Greg,
if your concern about cracked eggs are on the whites running out, i would suggest adding a tablespoon of white vinegar in the boiling water. that should keep the whites in.

or if it's the cracks that bother you, i usually wait about 30 seconds to 1 minute before i put in cold eggs. that had so far kept mine from cracking, and still cooks the eggs to my satisfaction. by the way, i take the eggs out of the fridge before i even start filling the pot with water to boil.

Subject: Problems?
I tried this Technique twice and failed both times.

In the end the last bit of peel sticks still to the Egg and hinders complete peeling without breaking the Egg.

At which point could I have messed up.

....At which point could I have messed up.

perhaps at no point <g>

it is rumored that really fresh eggs can be more difficult to "peel" -
another theory says start with the eggs at room temp

for the cold water "quench" I like to use actual ice water - a bowl of cold water with a bunch of ice cubes....

and then there are some eggs that simply will _not_ cooperate even when asked nicely.....


On August 24, 2008 at 06:21 PM, Michael Chu said...
Another tip is to use a slotted spoon to deposit each egg into the just boiled water - that prevents them from possibly cracking as you "drop" them in.


On August 26, 2008 at 04:56 PM, an anonymous reader said...
I agree, you HAVE to use a spoon to lower them into the water. Otherwise you will definitely get cracked eggs, especially if the water height is 1 inch above the eggs!

Ah, here freshness of the eggs makes a difference. Older eggs are less likely to crack when you have ample water because they float (due to the air pocket in the big end) and won't smack into the bottom of the pan.

The recipe as tested didn't work for me, but a slight adaptation worked best.

Follow all instructions up to removing the pan from the heat. Turn off the burner, but leave the pan on the heat for 5 minutes. Remove eggs, shock in cold water, enjoy .

Maybe the make of my pan lets the water cool more quickly or some other reason. Whatever the reason, this slight modification worked perfectly for me. I've never managed to make soft boiled eggs that perfectly.

Also, for peeling, I gently tap with the dull side of a table knife to crack all over, then gently peel.

If the shell is a problem, there is an easy solution, get rid of it before cooking.

This is how I do it:
1. Cut a square of plastic film about 25x25 cm
2. Cover the inside of a cup with the plastic film, spray the film with olive oil
3. Crack an egg in the cup, add salt and pepper to taste
4. Carefully make a small package and tie the edges with some thread (I have used dental floss)
5. Boil the egg 5 to 7 min.
6. Without pinching the egg, cut the thread and remove the egg from the plastic, sometimes it sticks, so be careful.

Ps: I learnt this technique from Jose Mari Arzak @ Restaurante Arzak in San Sebastian, Spain,

Wouldn't you have to figure in the elevation at which the eggs are being cooked to determine the amount of time to cook them?

Subject: Cooling eggs after cooking
For hard-boiled eggs, quenching them immediately helps prevent the yolk from getting a greenish tinge on their surface (resulting from a reaction between sulfur from the white and iron in the yolk).

Subject: Eggs hard to peel
You can add cream of tarter to the water before boiling and it will make the new (fresh) eggs easier to peel.

Subject: Altitude? ..for cooking eggs?
A couple of viewers brought up 'altitude' ... which begs the question: "What altitude is recommended for best results?" (note: I live in a split-level home ... the stove is on the upper level.)

Altitude affects cooking because air pressure is reduced at high altitudes. With a reduction of air pressure comes a lowering of the boiling point of water which will reduce the maximum temperature that water in an unsealed container can be brought to (and thus how much a food cooks in a given amount of time). The difference between ten to twenty feet (an indeed a few hundred feet) will not make much of a difference. However, being 5,000 ft above sea level will affect your ability to replicate a recipe that was developed for use at or near sea level.
