You stick cookie dough into an oven, and magically, you get a plate of warm, gooey cookies. Except it's not magic; it's science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we can kill salmonella, and why that intoxicating smell wafting from your oven indicates that the cookies are ready for eating.
Lesson by Stephanie Warren, animation by Augenblick Studios.
Here are the Celsius conversions:
Butter melts at 33.33
Salmonella dies at 57.77
The proteins reaction happens at 62.22
The water boils away at 100
Maillard reaction at 154.44
Caramelization at 180
And 350 oven is 176.66
Thank you. I wonder when the US will finally arrive to the 21st century.
The hero we all need
Thank you, I genuinely thought the cookies were being burnt with those numbers
Thank you! I was coming here to complain that they should base it on ºC since most of the countries that view this don't use ºF
Thank you!
Dear TED,
6,7 billion people use Celsius instead of Fahrenheit. You could at least WRITE the respective celsius temperature in the video.
Greetings,
all sane countries outside of the US.
Or perhaps you could just learn how to convert it... like us insane people in the US do with everything Celsius. Peace!
***** °C = (°F - 32) * 5/9 ...yeah I'm so going to remember that for every single random moment in my life (which is, in fact, not often) when I stumble upon a Fahrenheit degree :P
mogami4869 Exactly my point really. For even as often as I run into Celsius working with computers, I can never get the conversion right off the top of my head. Thankfully, there are places like www.metric-conversions.org/temperature/celsius-to-fahrenheit.htm to help me out in those times.
Peace!
*****
Best solution would be the US finally adopting the metric system like all other countries (except US, Liberia and Burma)
Omnilatent
I agree. But from my experiences, you can't change the world... you can only change yourself. Peace!
I didn't know there was so much science in my cookies.
Hehe you didn't know
I know right
Exhalant
Lol
Exhalant cookies! YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSssssssssssssssssssssssssss (eats all of the cookies right after the cookies had baked) yummy! :3
rasheedat ekiyoyo right! Baking is actually a science
Baker: Oh no! We've been found out! Chef: Hide the test tubes and colored liquids!
He's learned too much!
Kyla Montenegro coloured*
@@eriust5227 Different ways to spell it, colored in the US and coloured in Canada and the UK
Big Toe Fungus vs. Fried Po Chungus heheh ok
Lol!😂
How many countries on this planet use Fahrenheit.
+TheChaosLp
Like 2 or 1 ugh yeah
USA, Belize, Bahamas, Cayman Islands
*has lived in the U.S. most of his 16 years of life.
*Understands the Metric and Celcius better than the Standard System.
*Can't even remember how many feet are in a mile and the boiling point of water in fareinheiht.
*knows the boiling point of water in Celcius though! Because 0 and 100 is easier to remember than 32 and 212 (yes I googled it)
Adadave what is shorting
I think the Bahamas stopped using it recently so...even fewer countries use it now, a total of 3.
Former baker and honours graduate from baking school here. You forgot one of the most important steps! Creaming the fat (butter) with sugar creates air pockets in your dough. This process leavens your baked product, always cream your fat and sugar until light and fluffy if you want a light and fluffy result.
@@vincikeeper1581 it's a combination
Also, baking soda is sodium hydrogen -carbonate/ sodium bi-carbonate, not sodium dioxide. Not that its really important tho
would this cause the cookie to taste more crunchy or cakey?
@@sofiaazira5551 both! The carmalized tops are crispy, but the inside is cakey and chewy, somewhat like a marshmallow bread of sorts, in my experience.
Can I still cream the butter when the cookie recipe calls for melted browned butter?
I remember my sister once told me that when she was interning with this baker at this buffet that also had a bunch of desserts, including cookies, she told me they didn't have timers for almost anything in there. The head chef would just...zip over to the oven and pull out the tray after some time and always, the stuff that was being baked in there comes out perfect. It was very fascinating and hilarious to watch because she'd yell: "Out of the way!!" And everyone would part like the Red Sea while she makes a bee line ot the ovens.
Yeah that's an eyeballer right there, I come from a family of them. We eyeball everything and it always turns out fine. But it's hard to describe directions because we don't really follow measurements lol, we just adjust things a lot depending on how many people we feed
I love the intro! "It's color darkens- ominously." "Then, the kitchen timer dings. Your cookie is ready." I was like: did I press the pluto video?
90% of the comments: no Celsius really?
The rest: something else
just look up the conversions🙄
@@missgworl3918 it's annoying pausing the video every ten seconds and moving to a different tab to calculate the temperature, and then going back to keep watching.
C is for cookie and also for Celsius, which you apparently haven't heard of.
FFS mate, we have ways to convert Fahrenheit to celsius, figure it out for yourself.
baldrick Triffid in korea,C is for Chickens!
Let me correct you there: South Korea. In North Korea, the chickens went extinct due to hunger (may or may not be true; I'm just joking)
CARBON...
LOL
"Bakers are mad scientists" best quote I ever heard
ikr😀
same
"yes I am a mad scientist how do you know"
Fantastic video. Simply loved it. I love baking and agree to the fact that I use the sense of smell to decide when to go close to the oven to check whether my cookies are baked!
And all this time I thought cookie monster was just an addict... Clearly, he was addicted to science!
I love his voice. He can make the science of baking sound like an epic thriller.
Everyone Here: Use celsius C
Me: Use kelvin K😂
lol
"You know i'm something of a scientist myself"
Bruh
Americans: Farenheit Better! Rest of the world: Celcius BETTER! You, an intellectual: KELVINNNN
Fahrenheit and Celsius people: we have found a common enemy
If you ought to show temperature, use both CELSIUS and FAHRENHEIT. Not everyone knows fahrenheit.
Just do some math
I agree. I have troubles too.
just some math.... multiply by 1.8 (or 9/5) and add 32
yeah nah
Christopher Eugenio and DEGREES
YES I AGREE WITH HIM! COME ON TED-ED! my first ever complain of this channel, everything else: PURRFECT!
Sad because °F. When will we be rid of it? When?
+Ed Wiebe miles, gallons, ounces, all of that shit's gotta go too.
+Ed Wiebe Never
Robert Persons Unfortunately that's probably true.
+Robert Persons Yeah, Americans are just too awesome. heh
Robert Persons I wouldn't have phrased it quite like that!
"If you're ideal cookie is barely brown, like a Northeasterner on a beach vacation" LMAOOOO
I suddenly want to bake, I'm hungry.
I'm a little hungy, you know what I'm saying?
My day wouldn't ever be complete without hearing addison's voice
addison rae...*strangely wicked face of astonishment*
TEd-Ed never fails my expectation for scientific animations.
Love the complex science behind simple things
this video is 7 years old and yet i come back it
something about his voice is very soothing
That's an absolutely perfect explanation. I understood some of it and I'm pretty sure that the person watching this that have interest on cooking and science love this
I love how you explain those difficult concepts! Thanks a lot
This animation is amazing! Whoever did the visuals for this needs a raise. and a hug. and a lollypop.
I adore the beginning of the video where you somehow make the process of baking cookies sound interesting
I literally just did a lab on chemical reactions in cookies and I hadn't thought of youtube as a source of info. Nice video.
Cool
My grandma makes cookies all the time and I didn't even know there's so much science into it!! Thank you TedEd
thank you this helped me write my homework essay "tell me about a chemical reaction that happens of your daily object or tasks in 1000 words"
I've always liked that last punchline at the end of each Ted video, it brilliantly sums up the whole video in a very humorous and interesting way
this video is really cool I didn't know cookies were so complicated please make more food videos like this
I didn't mind because the subtitles in my language have all the temperatures in °C. Thank you, subtitle person.
I know that everyone is getting all worked up about how they didn't use Celsius, but can I just say that I love this flat color animation?
Please include celcius as well. I thought TedEd is for international.
chronousnemesis how the heck was he supposed to know to put both temperatures
Unnati T well just use C
its an american company and just google it its what we Americans have to do
can't you just use a converter?
it's not international they speak english
This was an amazingly well put video. I want to take the rest of the day off and go bake cookies.
Fun Fact: The animation studio who animated Superjail (Augenblick Studios) collaborated with TED-Ed and has been shown at millions of schools. It’s obviously nice to see a (sorta) well known animation company to do this masterpiece
I'm sorry, but raw dough is worth the risk! ;)
*gets salmonella poisoning, dies*
worth it...
You can make edible dough that's easier to make and you eat it raw ._.
Yumeni I can eat non-edible dough raw can't I?
Heres what you do: put the dough in the oven till it reaches the heat level that kills the bacteria. Your cookie is now mushy and safe to eat AND its warmmmmm...🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪
Josh Werner You can make cookie dough without eggs! No risk of salmonella.
Really appreciate the writing in this.
First of all, I don't appreciate you infecting me with the idea of steam being an alien xenomorph bursting from formerly delectable pastries.
Second of all, the aforementioned statement is in fact false; I played that segment back 2x because it was freaking amazing and I'll happily carry that mental image for the rest of my life.
One of my fave episodes God bless and thank you!
I want a cookie with a nice tall glass of cold milk now....
milk taste bad :-(
Bam the turtle no sir
@@komyobkomyob7013 Only tastes bad out of plastic. Get some milk from the cardboard cartons that flip open like the ones we used to have in school. So delicious.
Lmao I made chocolate cookies but they taste so bad with milk and now I regret it :-: but hey I still have fresh cookies!
One of the reason that makes me happy to apply to my major in college (Food Science)
This was fascinating and beautiful to watch. You have some serious sewing skills. Thanks for sharing.
Please use international standard for measuring temperature.
AMAZINGLY AWESOME!!! I need to learn more about foodchemistry
😍
I've always loved baking and almost anyone who's tried my food loves it. Then I entered science class in middle school and I excelled. My teacher really liked me. People would laugh if I said that a baker is basically a mad scientist they would laugh, but lot of what I had to learn in science made sense because I baked. People who make food are also artists picking out they perfect ingredients to create amazing visuals as well as tastes and smells. Don't you love it when you can stuff your face with food while sounding smart?
Madelyn Poling Obviously you have time, but may i recommend food sciences as an area of interest/ possible college path for you? It sounds like you'd love it.
Your videos are great !, I use them for my science class, the big problem is that when I work with young children, I need them in Spanish :( (I know there are many translated, but not all) Thanks for your work!!!
This is the very first time I actually feel like I'm going to be a great baker 😆😆😆 Arigato 🌼
Thanks for the fun video and informative descriptions! Love it!
I'VE BEEN LOOKING FOR THIS MY ENTIRE LIFETIME ON THIS PLANET WHERE TF HAVE U BEEN?!
This came up in my recommendations just as I was waiting for my cookie dough to cool in the fridge.
This video provides a great explanation of the chemical process that occurs during baking most cookies and pastries. If this kind of stuff interests you then you're likely to enjoy Harold McGee's book, "On Food And Cooking: The Science And Lore Of The Kitchen". It is somewhat technical, yet written so as to be understood by non-scientists. It is one of the required "textbooks" (if one can call it that) at many well known cooking schools. You'll find most professional chefs usually keep a reference copy handy.
Qué buena explicación, es perfecta para entender varios procesos científicos y por supuesto la deliciosa preparación de las galletas. Gracias por hacerlo tan fácil de entender
My mother hates caramelized cookies so youre right about the northeastener part except for me I like crunchy cookies as long as theyre a bit doughy in the middle.
These videos really motivate me to study hard on my AP Bio LMAO It's actually interesting for me since I love baking
The introduction in this video accurately describe my disastrous face, invaded by acne.
Hi Ted, I really like food chemistry so more videos on the subject are welcomed
Bu videoları izledikçe kültürleniyorum💛 thank you soo much ted-ed family🌝
THANK YOU SO MUCH !..MY TWO FAVOURITE THINGS IN THE WORLD ARE ART/CREATIVITY AND SCIENCE IN THIS VIDEO !
Too bad I now don't have any clue at what temperature I should bake my cookies, since I only know Celcius. In fact, the younger generation of people in the whole world except for the US uses Celcius.
*****
Sure I could do that... for _all eight_ temperatures he mentions. The whole story is about the right temperature for the right process, and I can't follow the story when I have to look up the temperatures every twenty seconds. It is also a bit short sighted to think the world consists only of the United States of America, who (according to Wikipedia) are the only large nation still exclusively using Fahrenheit. Mentioning the Celcius temperatures would have made the story much more enjoyable and easier to follow. At least for me.
***** It's not that much of a big deal, I still learned something the video. But imagine all temperatures in the video were in Kelvin. Then you and I both would have little idea as to how hot or cold the mentioned temperature is, relative to what you know. Sure, Google can convert it. But still...
Fret not. Your computer has a handy calculator which automatically converts Fahrenheit temperatures to Celsius.
Virtlink
Actually that would still be easier than Fahrenheit since you only had to subtract 273 from it for Celsius. I don't need google for that.
Virtlink subtract Fahrenheit by 32 then divide it by 1.8 and you have the point, kinda annoying when watching this video then pause to calculate the temperature of each process
The "puns" at the end of almost every TED-Ed video are what give life to my empty soul
20 seconds into the video: When i clicked this video i didn’t expect the opening of a horror movie
30 seconds in: .....Dude you know how to make cookies scary
As a pre-med.. nutrition science major, this video made my night 💛
Would have been nice to see the Celsius conversion on screen, if only to show that TED acknowledges a world wide audience.
Love it! Helped a LOTTTT for my science project! :)
Cool! My teacher showed us this before we baked our cookies
He is the best voice on Teded
Could you please explain more on how "water escape when butter starts to melt". Where is the water from, is it from inside the butter?
Thank you
What an entertaining, concise, and comprehensive "overview" of the #science of #baking #cookies! Everyone should watch this if they've got 5 minutes to spare :)
That opining description is so funny! Couldn't stop giggling!
I was actually watching this while baking cookies. No joke, I'm making them for a group tomorrow.
When you use such exotic systems like Fahrenheit, make sure to put its equivalent in Celsius as well, that way you may reach a much broader audience!
Very nice video, but holy shit does it grind my gears if Americans ignore the other 90% of the world and 'forget' to at least include Celsius next to their beloved Fahrenheit.
Well, 212*F is 100*C and 32*F is 0*C, so knock off 32, divide by 9 then times by 5 for the Celsius/Centigrade number.
Or in more mathematical equations ((*F -32) ÷9) x5 = *C. Reverse that for *C into *F (so ÷5, x9, +32). So ((356-32)÷9)x5 = 180*C
Of course, you COULD flip the divide/multiply stages around (so times by 5 THEN divide by 9 going *F -> *C), but that'd break the order one does mathematical equations in! :P
Or just remember every 18*F is 10*C. Starting from freezing water: 32F:0C, 50F:10C, 68F:20C, etc. You get the picture.
aapenjong and does it grind my gears when u people are so triggered at anything that doesn’t include you! These comments need to stop. If there was no f, I would deal with it, not triggered and insulting like all these rude af people!!!!
awesome narration!
I love this art style
People please stop arguing about Fahrenheit and Celsius.
There are several English-speaking countries using Celsius while America is the only one using Fahrenheit.Use it for local weather only.Education should be clear for all.
@@daniellbondad6670 don’t worry, they use it for science and education. Most scientists in America probably automatically know to use both, so you don’t have to worry.
2:20 "the steam evaporates"
Correct me if I'm wrong but isn't steam by it's very definition already evaporated?
huh something to ponder on and YOU WROTE THIS COMMENT 7 YEARS AGO!!!!!!!!!!!
Very informational! Thank you!
Regarding egg proteins, 62 °C to start to 'solidify' is very optimistic in a recipe with high sugar concentrations. 62 °C is for pure egg. I would say 70-75 °C will be more relevant as a starting point, probably 85-90 °C for decent binding.
okay, last video of the day...
楚天庙口宇 NOPE
宇庙口 stop lying
*4 years later*
1 MORE
what a nice video!
hope you do more :)
I need more videos like this!
to comput from F to C silply: Deduct 32, then multiply by 5, then divide by 9
This makes me want cookies
Love it! Very nicely done indeed. Just one thought re the °F/°C debate - why not make two versions of the same video? Just like doing one in another language but a whole lot easier, and by doing so expanding the 'viewership' to millions more...
Or put Celcius and Farhenheit together, that work too.
Watching this for online school! :)
beautiful narration
I love cookies and I love science! I take this way too seriously, but actually I don't bake :3
what a beautiful and informative video this is :)
I can't understand this but how exciting is it to watch it
Wow! Who's mouth watered just now
I've eaten tons of cookie dough, all my life, many times a year. Still haven't gotten salmonella, and neither has anyone else in my immediate or extended family on my mother's side, where eating raw cookie dough is tradition.
Better watch it, you might just get it now!
MDkid1 ...
Same here. But you gotta keep the lawyers happy.
I love cookie dough. It's delicious
Did you sterilise the dough?
Thank you for doing this, I love all of your videos ❤
Oh I love the way to explain this scientific information which is hard to understand, with very cute images. That made me more interested in baking :)
Two of my favorites: Food and science.
A nice video, but please at least write Celsius degrees in parentheses! Especially when there are so many to look up!
The world operates on Celsius. I'd love to see it with Fahrenheit in small text parentheses.
Well yes, if I were to skip being polite, I would rephrase my previous comment thusly: "Switch to metric, morons!"
Very interesting! However, they didn't mention what happens to flour :(
Simple explanation. I have to watch again with my little sis.
I’ve always had a great internal timer for baking
