Chocolate!!!

Posted in: Best of the Blogs, Life & Culture

One of my favorite of MIT's 500+ student groups is called the Laboratory for Chocoloate Science. According to their Wiki, LCS can be described:

 

Founded in 2003, the MIT Laboratory for Chocolate Science (LCS) is a student club dedicated to spreading the appreciation of chocolate on campus, and to bringing opportunitites for learning about, appreciation of, and indulgence in our favorite substance to the community.

 

In today's (Wednesday's) edition of the Boston Globe, the second major media article about LCS will run. My favorite discovery from the article is this video:

Here's the article itself:

 


 

 

At MIT, a hunger for chocolate knowledge

CAMBRIDGE - Conversations about chocolate typically revolve around the obvious: flavor, intensity, milk vs. dark. But for the students in the Massachusetts Institute of Technology's Laboratory for Chocolate Science, the discussion runs a bit more, well, technical.

You may learn, for instance, that chocolate has six crystalline states and that heating it too quickly can separate its molecules and cause it to become gritty. Or: When chocolate absorbs moisture, fats and sugar crystals rise to the surface or "bloom," causing it to take on a whitish sheen or oily texture. (Hence the film you might find on last year's Christmas candy.) "It's fun to explore the different sides of chocolate," says Allison Kunz, 23, who graduated last year and still attends the group's events. "There are scientific, political, and business aspects."

The laboratory, which is essentially a chocolate appreciation club, formed in 2003 as an extension of then-student Ariel Segall's truffle-making parties. Today, there are about 10 active members - mechanical engineering, chemistry, material science, and mathematics majors united by a love of cocoa - and close to 500 people on the lab's mailing list. They come together regularly for tastings and chocolate classes; most events are open to the public. To generate interest, the chocolate enthusiasts don matching pink or brown T-shirts featuring molecular diagrams of chocolate and coffee and set up a table near the entrance of freshman orientation or activity fairs. "We'll have fondue - people can dip strawberries or try chocolate flavored with strange spices," says sophomore Anna Waldman-Brown, 19. The spread, not surprisingly, is popular and draws in members.

During the school year, the group raises money through truffle sales. They make white, dark, and milk chocolate varieties, flavored with everything from habanero pepper to chai tea. Two of the more unique (and potentially off-putting) flavors the group has experimented with are wasabi-lime truffles and Marmite truffles. Members joke that they should create a "Beaver Bar" - a treat named for the school's industrious mascot. Students are known to serve hot cocoa during finals and hold brownie bake-offs. Earlier this year, a representative from Kallari - a sustainable chocolate-making cooperative in Ecuador - spoke at the school.

At a recent dinner the lab put on, self-described "chocolate freak" Ian Hawkins and his wife, Bronwyn, sampled white-chocolate potato curry and chicken mole. The couple, who live in Boston, found out about the Lab for Chocolate Science at WeirdBostonEvents.org. "I'd love to have the bank account to only buy good chocolate," Hawkins says. But not with today's "financial apocalypse." He'll be back at MIT for more tastings.

Students may adapt the tasting terms used to describe wine and other foods - i.e. fruity, oaky, and earthy - to chocolate. Small San Francisco-based chocolate manufacturer TCHO, for example, uses a flavor wheel to differentiate and label its products.

This group has a thirst for chocolate knowledge, but the students are also motivated by a sweet tooth. "We just love chocolate - we're really passionate about it," says senior Meghan Reedy, 21.

A Lab Where You Can Lick the Test Tubes


By KATIE ZEZIMA
Published: Wednesday, February 11, 2004

 

CAMBRIDGE, Mass.

AS two pots of viscous goo bubbled away beside Susan Born in the dank, fluorescent-lighted classroom, she described for a rapt group of 30 students the molecular composition of the substances and, with the aid of time-temperature graphs on the chalkboard, discussed lipids and their solubility.

A fairly typical scene at the Massachusetts Institute of Technology. Except this was not a materials science class. It was a meeting of one of the school's newest student organizations, a chocolate appreciation club called the Lab for Chocolate Science.

Ms. Born, 28, a technical writer and 1998 graduate of M.I.T., gave a two-hour lecture on the science of chocolate with pots of melted chocolate chips as props. Professors argued whether chocolate could glassify, and words like eutectic -- something to do with melting points -- hung in the chocolate-scented air.

The group was started last fall by Ariel Segall, 23, a senior from Englewood, N.J., whose chocolate fascination dates from childhood, when, by age 10, she had developed a preference for dark chocolate from Zabar's. By her early 20's, she tasted a Black Pearl truffle, a combination of wasabi and ginger dipped in dark chocolate and sprinkled with black sesame seeds, from Vosges Haut-Chocolat in Chicago. Inspired, she replicated the flavor with friends and started being the host of truffle parties two years ago. The lab is an extension of those parties and a way to experiment with the types, flavors and textures of chocolate.

The chocolatiers' first experiment was making 4,000 truffles for a freshman fair.

While many came to the lecture for the chocolate -- leftovers were on sale from the group's last truffle sale, which included cardamom-Kahlua, hot pepper-cinnamon and peach-passion fruit -- since this is M.I.T., many wanted to know if they should take their test tubes to the next meeting.

"We'd gotten some e-mails from people wondering if we were an actual laboratory," said Kat Allen, a junior and the treasurer of the group, which now boasts about 20 full-time members.

In a place populated by chemists and engineers, group members knew it would be a hit with students. Ms. Born added that a fashion trend among students and alumni involved T-shirts bearing molecular diagrams of chocolate and coffee.

Who wears these shirts?

"Nerds," Ms. Born said.

Cocoa butter, along with cocoa powder, the main component of chocolate, is made, Ms. Born said, of fatty acids, including palmitic acid, a 14-carbon chain; stearic acid, a 16-carbon chain; and oleic acid, an 18-carbon chain. She said the mixture of fat in cocoa butter has six stable stages -- distinct consistencies -- which is why processors have to temper, or heat and cool, chocolate, to attain the desired consistency.

Ms. Allen and Ms. Segall were keeping an eye on the pots of chocolate, dark chocolate chips in a slow cooker and white chocolate chips in a double boiler. Once melted, Ms. Allen poured the dark chocolate into a Pyrex container and the white into a metal bowl and added water to each, altering the crystalline structure of the chocolate (known as seizing). The dark chocolate became gritty, while the white chocolate looked like an ivory and yellow oil slick.

"The part I liked the most was when they explained the three different fatty acids," said Vigi Braviam, 27, a postdoctoral biology student. "Now I feel like I can mess with my chocolate a little more. I can just add more palmitic acid, and it will solidify a little more." Palmitic acid, she said, is just palm oil, which she can buy at a local chemical supplier.

The club plans to continue its nonscientific activities, like brownie bake-offs and chocolate tasting. But Ms. Allen thinks the science of chocolate could catch on.

"It would be cool if we could teach an actual for-credit class one day," she said, "but that's pretty far out there."

 

 


 

And for those of you coming to CPW... the Lab for Chocolate Science will be one of hundreds of student groups represented at Saturday's Student Activities Fair. Yum!

SO excited for this -- thanks Matt! smile
Also, I think there's something going on with the site... the first time I tried to post, I was told that there was an error because I had posted too recently. I haven't posted on this web site for about 3 weeks or so. Can you fix this?

Posted by: Alex '14 on April 8, 2009

Oh no! I'm sorry... it actually did go through the first time. I guess I must have clicked the button twice by accident and messed it up... sorry ):

MMMMM. Chocolate. I am definitely paying the LCS a visit while at MIT. I love chocolate. This has been one of the most enlightening blogs for me ever. Thank you Matt.

Posted by: Alex '13 on April 8, 2009

I saw this post this morning and am making the trouffles as we speak. It sucks to love chocolate and sweets and to like making stuff like this and be diabetic...but at least my neighbors like me a little better than my brother for the extra food they get raspberry

Posted by: Zeke '13 on April 8, 2009

Must have: ,

Posted by: Valentine on April 8, 2009

awww, the white chocolate coating was really hard to do :O apparently ghirardheli white chocolate is too...something that makes it not get as liquid as you'd want it to get. They still came out awesome but looked extremely disgusting raspberry I am definately visiting LCS next year!

Posted by: Zeke '13 on April 8, 2009

AWESOME CLUB!

Posted by: Spark ('14?) on April 8, 2009

That sounds amazing! I love chocolate. If I could visit, they would definitely be on my priority list of people and groups to see. Thanks for sharing this!

Posted by: Anna on April 8, 2009

I can't believe my luck! My son wants to attend MIT (that's how I found this post) and I happen to be in chocolate direct sales . If anyone wants to make extra money selling chocolate, you can do in-home chocolate parties (like Tupperware but with chocolate). You can get more information at my website
www.dove-chocolate-discoveries.com/carolyn
I would love to have more chocolate lovers on my team!

Posted by: Carolyn on April 8, 2009

Zeke-Dove Chocolate Discoveries just came out with a sugar-free Dove chocolate. I haven't opened my box yet, but I have been told it tastes just like the regular chocolate from Dove.
Also-Dove just came out with white chocolate. It is so good! Now this I have definitely tried and loved! My daughter only likes white chocolate and she gives this a thumbs up!

Posted by: Carolyn on April 8, 2009

This is the number one reason I am attending MIT next year. (Would it be terrible if I was only half joking?)

Posted by: Bridger '13 on April 9, 2009

Oo.. I can't wait for cpw!

Btw, I'm from California and am not sure what to pack. Tips anyone? Thanks in advance!

Posted by: 0 on April 9, 2009

WOW. Simply amazing. This is going to be one of my main reasons for choosing MIT.

Posted by: Rach on April 9, 2009

very random question that's complete unrelated to any conversation here.

Just curious, but when do we get MIT email accounts, and how do they choose the name?

it's a random question, but I've always wanted an email of
myname@collegeofmychoice.edu.

Posted by: Justin E '13 on April 9, 2009

I have a question, but not about MIT, chocaolate etc. Can somebody explain me what "Karma police" means? It's phrase from Radiohead song ("Karma police", record "OK Computer", 1997). I have now Easter holidays and I can't ask my English teacher.

Thanks in advance wink
Sorry for digression wink

@ Jolka

Well Radiohead lyrics can be quite vague and its analysis is quite subjective. But the general idea seems to be about coming to terms with your conscience.

"Karma Police" refers to that voice inside your head which tells you to stop judging people based on petty differences.

See the video, and read "Mr. Ayl E. In"'s interpretation of it over here.

@Justin - They don't. You choose your username. It's useful to use your MIT username for employment stuff, so choose wisely. (That said, it doesn't need to be your last name. My username is "wings", which isn't sketchy employment-wise but is still fun.)

@Anon from California - Bring a warm sweater. I've never really needed much else smile If you want to be safe, you could bring a jacket too, in case it gets a lot colder.

Posted by: Piper '12 on April 9, 2009

Thanks Piper. do you remember when you get to begin using it? I love yahoo, but I'm ready for a change.

Posted by: Justin E '13 on April 9, 2009

Thanks Piper! Is there any need to bring waterproof boots? Are uggs ok?

Posted by: 0 on April 9, 2009

@K Thanks a lot wink

I really love Radiohead for lyrics - so strange, intriguing and curious. Sometimes baset with difficulties, especially for person who don't use English at home. And I'll be on concert of this totally awesome group ;D

Posted by: Jolka on April 9, 2009

@ Matt,

Did you get my mails???? Still waiting for a reply...

Posted by: SRV on April 10, 2009

Chocolate is just one mor ething to look forward to at MIT

Posted by: Ruhban Shah '14 on April 10, 2009

YES! this just makes cpw even better.

Posted by: hamsi on April 11, 2009

OMG!!! This is the first club I'm joining. I love MIT.

Posted by: Mel on April 11, 2009

@Justin - My email? As soon as I got it smile I highly suggest using a client like Thunderbird or Apple Mail rather than the online interface, though.

@Anonymous - You could bring waterproof boots, but I've never used anything but sneakers. I may be the wrong person to ask, though, since most people think I'm crazy when it comes to weather :D.
