The chemistry of cookies - Stephanie Warren

View full lesson: ed.ted.com/less...
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

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.

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!

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.

Also this video claims to be scientific but science speaks metric honey not some ridiculous system that is based on barley seeds.

[@null_pointer_deref]

BirdOfParadise777 you don't get the point. Using a converter is not a problem, but it's stupid to make a video with ºF measurement when nearly any country use it (like only 3 or 4). In adittion, you don't use Fahrenheit in a science video.

[@BirdOfParadise777]

Well, the point is. It is their video after all and they can do what ever they want. Whining about it won't change the video. Using a converter doesn't take very long. Being polite to the person/people who made the video and asking them to add C to future videos would be addressing the issue instead of whining and complaining about it.

Now a few questions, If perhaps someone uploaded a video in your language would you be pissed they did that? Would you be pissed they didn't upload it in english because majority of the world would understand it better ? A bit petty isn't it? Plus, If you still don't agree with me.

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.

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.

[@virtlink]

***** 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.

[@virtlink]

***** 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...

[@gcecg]

Fret not. Your computer has a handy calculator which automatically converts Fahrenheit temperatures to Celsius.

[@Omnilatent]

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.

[@nguyenbinhphuong1491]

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

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.

[@ElNeroDiablo]

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

[@tvieno]

[@SunyiSideUp]

"Why you no use Celsius"? Obviously this video was made by an American. We do understand that the rest of the world uses Celsius as their normal unit of temperature, but we don't. We use Fahrenheit. Complaining about it isn't going to change that our entire country operates using Fahrenheit (schools, weather reports, recipe instructions, our ovens, stoves, etc.) We didn't choose it ourselves, but it's been like that forever, and it's like that currently. If it gets confusing, just use google to convert the units. I always do that when a unit I'm not that familiar with is used.

look i’m all for the meters and liters, metric system is cool. but the way the fahrenheit, when judging weather, ranges around 0-100,, just makes sense. you know 32 is freezing temp but also that 0 is real cold and 100 is real hot. a lot less guessing because it falls in that range.
