In this Video Blog series, I embark on my own personal journey of learning to cook an egg. Many of us might assume that we know how to cook an egg, but if I were to ask 10 people to cook an omelette, I think you might get 10 very different looking omelettes. You would think that boiling an egg would be the easiest thing in the world to do. But how often do we still see that ugly grey ring around the yolks when we eat hard boiled eggs at the hawker stalls?
The humble egg is underrated and often taken for granted. But when bird flu struck a few years back, we were all lamenting that we could not order a Roti Telor and that our Char Kway Teow is just not the same. The fact is that the egg is one of the most tasty food around. On top of that, it's a great source of protein and it is very cheap. We all love the taste of eggs, be it Cavier (Sturgeon), Bottarga (Mullet), Ikura (Salmon) or even Hairy Crab roe. But we pay a bomb for these eggs compared to the humble chicken egg. If you were ever in the middle of Neo Tiew Village in the middle of the night with a bunch of guys in army green badly in need of a bath, the smell of fried eggs cooking in a mess tin is every bit as heavenly as any of the other eggs.
So let's start at the very beginning and learn to boil an egg. A simple thing you say, but yet there are so many people who marvel at the seasoned eggs that they serve with your Charshu Ramen. I guess we Chinese are more used to having our Lor Nerng hard boiled, so the sight of a seasoned egg with runny yolk is a bit of a conundrum. Actually the recipe is very simple and the key is to know how long to boil your egg.
The following video will highlight some tips on boiling and peeling an egg. Don't miss the bit at the end where I demonstrate a very interesting way to peel and egg which I hope will get you to say "Hey! I got to try that today!" I think it is an ieat original as I did came up with the idea and could not find it demonstrated anywhere else on the internet.
In order to get perfectly boiled eggs, there are several things to take note:
1. Boiling times will depend on several factors. Whether you put your eggs in and wait for the water to boil put your eggs directly into the boiling water will alter the cooking time. The boiling time will also differ if you use eggs straight out of the fridge as opposed to eggs at room temperature. I have found that the most practical way of standardizing the cooking time is to use eggs at room temperature placed into boiling water and start the timing when the eggs are placed into the water.
2. Fresh eggs are harder to peel than eggs which are a few days old because with the passage of time, the amount of air within the egg increases. So a few days old egg has bigger air bubble at the rounded end of the egg which makes peeling the egg easier. This is very important to note because if you are cooking the 5 minute egg for your Chashu Ramen egg, the egg is very soft and a super fresh egg is going to make the peeling process very difficult.
3. To prevent eggs from cracking when placed into the hot boiling water, you might want to use a needle to poke a hole at the rounded end of the egg to allow the air to escape.
4. To get the yolk to be in the centre of the egg white, stir the eggs around the pot when you place them into the boiling water.
5. In the video we demonstrated some really creative ways of peeling the hard boiled egg. But practically, I found that the most efficient way of peeling an egg is to quickly decant all the water from the pot and shake the eggs in the pot so that the shell gets cracked. Then immediatly soak them in cold water for 5 minutes. Soaking the eggs stops the cooking process immediately and prevents the ugly grey ring from forming. The grey ring forms because of the interaction between sulfur and iron in the yolk and white when the egg is cooked too long. The soaking also allows water to get underneath the membrane, lifting the shell off the egg white which will make it much easier to peel.
6. The method of blowing the egg out of its shell as shown in the video should only be done on Medium or Hard boiled eggs. As one of our readers have found, if you try it on soft boiled eggs, they might just break open when you blow the egg out.

Oh yes, as promised, let me share with you the method of cooking the Charshu Ramen egg. First you need to boil your soft-medium 5-6 minute egg like the one shown in the photo. Once you have your eggs peeled, simply put them in a plastic bag and add 1/3 soysauce, 1/3 sake and 1/3 mirin. You just need enough to cover the eggs. Leave them in a fridge overnight and you can sell your 20 cent egg for $1!
Special thanks to Sia Huat for sponsoring the videos! Sia Huat is Singapore's biggest retailer of professional kitchen equipment. I get my stuff there because you can find almost everything you need all under one roof. And best of all, their prices are very competitive and their service staff are excellent. I got my pizza peel, pizza stone and Tau Huay bucket from there. I also recently managed to buy my rotating vegetable shredder there. (You know, the type that makes nice long strips of carrots for Yu Sheng)
Thanks also to Mayer for allowing us to film at their live Kitchen at Orchard Central.
PS:
Please let us know if you managed to peel the egg like how we did in the video!

love the egg shot comparison. i never knew. i should stick this on my fridge :-)
hey les, when you say boiling water, is the pot still on heat? tks!
Yes, I keep it on a slow simmer. Some people turn off the heat but the cooking time will be increased. I find that it is not consistent because it will depend on the amount of water and the number of eggs. So I prefer to keep the temp at a constant 100 degrees.
i learn something new everyday! =)
you forgot to add....6. Make sure your floor is clean before you try the last method.. :)
One word for the video; Brilliant!
I like the way ieat peels the egg.
However the soft boil egg could be better.. The white is overcook.
I'm just curious how does coffes shop, especially the Sheng Siong at Serangoon north makes a perfect soft boil egg.
Thanks guys!
Anyone tried this at home?
I didn't watch the video but the egg thing has been a topic pretty much done to death by people scientifically interested in cooking, yet totally unheard of by the regular folks.
The main issue is the difference in cooking temperature between the yolk and the white, the latter cooks slightly cooler than the yolk, so if one sets the temperature appropriately, he can cook a solid egg with a runny yolk.
As with all cooking, like ieat mentioned, there's a lot of factors involved, but since the margin of error is large, lots of assumptions can be made.
1. Volume of egg and surface area, this will of course affect the rate of heating. The engineers reading this article will laugh and think of unsteady heat transfer formulas.
2. The temperature of the fire, ie the heating medium. As a zhichar chef can tell you, not all fires are the same temperature. You might argue that since water is boiling, the temperature should remain the same right and the heat source irrelevant? Ah, but this brings us to considering the volume of water used. This only applies if sufficient water is used such that no significant temperature change occurs when the eggs are put in the boiling water. In the first place, many egg cooking techniques don't use boiling water but instead a lower temperature water bath, which can probably be purchased at that kitchen appliance retailer ieat pimps. Ovens work too though, since ovens can be set at constant temperature.
3. The initial temperature of the egg. As ieat mentions, time and energy is required to raise the egg from 4 degrees to room temperature then to cooking temperature. So if you followed instructions on cooking eggs that were written for room temperature eggs, but used cold eggs, you could get undercooked eggs.
So cooking is the easy part, there are many different schools of thought on peeling, some people like to cold shock, others poke holes, that's probably up to oneself to decide.
This was a long comment as expected of someone rolling around at home from the shingles. Lol.
C'mon tj, you got to at least watch the video and tell us if they teach you my method of peeling an egg at culinary school!
Good job Les. Interesting nuggets of information throughout the post. : )
this is useful!! thanks ieat.
But I'm not from culinary school, they don't teach us how to peel eggs at NUS. We only learn how to talk about it. Mainly processed food, packaging, nutrition and other more technical aspects.
I watched the video, the guy looks skillful. Yeah that's one of the common methods (or rather, a variation of) that pro people use. That said, I've never done it cos I don't eat eggs in that shape much.
Haha I was just saying how unhygienic it would be to BLOW the egg out of the shell.
Eh the tap water idea not exactly very environmentally friendly if you have to de-shell 100+ of eggs that way, no?
Maybe Sia Huat can bring in an apparatus with a similar function that de-shell boiled eggs fast and furious (I'm sure they exist). If not, quickly go patent it if it aint already invented and dub it the "egg pump"!
Meanwhile, I'd just stick to peeling the eggs in a cold water bath as opposed to running tap water.
Never thought of making an egg has so much knowledge. Les, thank you for sharing the knowledge.
Hello Dr Leslie, thank you so much for sharing how to make chasu ramen eggs!! I LOVE THOSE EGGS!!! Now, I can impress my guest! Hehehee..your way of blowing the egg out is very nifty.
Glad you all found the information useful!
There's more to come as we explore how to estimate the age of an egg without cracking it open. Plus some really good breakfast recipes to impress your significant other!
my savior!!! i've been looking for ramen eggs here in manila, like the ones i had in tokyo but to no avail... but now i know how to make one on my own! THANK YOU!!!
I'll blow my eggs out of their shells. Pretty nifty trick.: ) Even your chef fren was impressed. You should organise a makan session at the restaurant he's working in for us.
Hey Leslie
I really enjoy this Egg Post. Simple, yet profound & very useful in our daily cooking ; ) I enjoy the frequent use of video clips in your blog too! Tks! Keep it up!
Cheers
Ping
Thanks Ping,
Any egg dishes at your restaurant?
Hi,
No..not at the moment. I just like to have my Casear Salad with a 6min egg ;) Haa..my personal high protein diet.
hi leslie,
tried your method for fun of blowing an egg since we're eating it ourselves. perhaps should put a note of warning there that it is not suitable for medium boiled type eggs that we're cooking for the charshu ramen. maybe suitable for hard boiled eggs only? we wasted 3 eggs through blowing cos the impact made the yolk explode all over our palms!
Fantastic! My Charshu Ramen Egg turned out perfect! And it is very easy to do!
Ah thanks for that comment rachel! I should let people know. Sorry about your 3 eggs!
haha, but your two methods of flushing out the eggs really worked. it was interesting doing it and the high pitched 'sound effect' produced added to the fun though we ended up eating the eggs off our palms straight away!
thanks for the video, now that we can make homemade ramen eggs i doubt we'd be paying for them at restaurants now :)
Wow... Seriously i learn new things everyday! I never knew u could flush out eggs like that!
Soft boil egg in singapore is a very nebelous thing... everywhere has their own standard. for me i like mine, room temperature egg into boiling water remove from heat covered sit aside 14mins.
Anyway just a little egg knowledge i have. Egg white starts coagulate at 62 degC while egg yolk starts at 71 degC. Technically its possible to have a totally runny yolk and solid white :) But it will take ages...
The picture u have with timing, u can't say it works for all eggs right? i mean i do larva egg @ 7mins instead of 5.5mins so probably my eggs are bigger then yours :P Size do matter :) even when the ladies say they don't... hehehehe...
About peeling eggs got 2 method. commonly used in industry for production. either roll the egg on a flat surface to make the shell crack and just take them out whole with membrane holding on to the shells or to use a very sharp knife just cut half and scoop out the eggs.
Temperature of water can varies even when it looks boiling. Normal water boils at 100 degC but water with salt boils at a higher temperature while water with vinegar boils at a lower temperature. Depends on what you wanna do. For example poach eggs, the reason of adding vinegar is to lower the temperature of boiling point and acid aid coagulates proteins in egg white leaving you with solid white and runny yolk :D
And peeling egg in water not only help peeling egg easier because water get in between egg and membrane, it also helps wash off egg shells because no one like to eat eggs with crunchy shells :D
And about estimating age of egg without cracking open is not that tough :P u actually gave hints in this post already :)
Cheers,
Wilson
Ah thanks for your points Wilson, and not giving too much away. There are five episodes in the egg series and you don't want to spoil the fun by giving away the punchline!
the french chef pepin put a small hole to get rid of the ammonia smell.
