Scientists Develop Chocolate That Won't Melt At High Temperatures
Zothecula writes "One of life's less pleasant surprises is discovering the chocolate bar that you forgot you had in your pocket on a hot day. Two scientists working at Cadbury's research and development plant in Bourneville, U.K., are fighting that gooey surprise with the invention of chocolate that remains solid even when exposed to temperatures of 40 C (104 F) for more than three hours. Aimed at tropical markets, the 'temperature tolerant chocolate' is described in a World Intellectual Property Organization (WIPO) patent application."
Melts in your Mouth. Not in your pocket.
Tic-Tac-Toe, Global Thermonuclear War, and relationships all have the same winning move.

From TFA : Temperature tolerant chocolate has been around since the 1930s, but it sucks because it becomes too hard and tastes bad.
I can't wait to try a bar of this stuff and compare it to the normal kind. Obviously, since it doesn't melt in your mouth, it won't be the same, but if it is soft and easy to chew, and disolves in saliva, maybe the eating experience will be similar.
Personally, I find the most enjoyable chocolate to be Hershey's Symphony bars that have been frozen.
Not going to melt in your mouth unless you have a high fever.
So it's going to be like chewing on chocolate flavored crayons.
Exactly: chocolate melting almost exactly at body temperature is a feature not a bug.

If your chocolate bar remains hard for more than four hours, please see a confectioner.
...is when I try to eat a frozen chocolate on a winter day. It tastes like goo. Can it be, because it does not melt?

Although, unfortunately, I can't say I've ever forgotten about a chocolate bar that's in my possession.

High temperature chocolates are not new. In WWII, the US Military created emergency rations in the form of chocolate bars (http://en.wikipedia.org/wiki/United_States_military_chocolate) that remained solid up to 120 degrees. It was kind of an in-joke how unpalatable they were, but this was part of the design. As an emergency ration, they wanted you to have to be *really* hungry before you ate them.
And Cadbury was already licensing the technology, IIRC. I read the recipe in a magazine years ago (apparently invented by some schoolkids) and actually made it. The trick is to melt the chocolate down, mix in a little glycerine, and let it set again. It works pretty well, although my chocolate is pretty soft even when it's not melted. Could be I did it wrong.
Is when that's not chocolate in your pocket after all ;-)
You'd have found it was just a remake of the WWII era tropical bars. I ate a couple (of the modern remakes, I was in .mil in the 90s). It was icky.
You know how cheap american chocolate (Hersheys) is like room temperature brown colored Crisco? The tropical stuff was basically the same stuff but a texture / mouth feel more like refrigerated brown Crisco.
I imagine this "invention" is about the 4th generation re-invention. Food science is just like IT, every decade or two, the same old ideas get lipstick and a new dress on the old pig and a big announcement about the new baby, while the old timers roll their eyes, not that crap again....

Isn't one of the "good" characteristics of chocolate is that it begins to melt in your mouth? If it doesn't melt at 104F, I don't see it melting in my mouth.

This is kind of missing the point that Chocolate is supposed to melt at body temperature, it is this feature of Chocolate that makes it unique.
My dream of living in a house made of chocolate may one day become a reality!!
Taking chocolate to the other extreme, dunking it in liquid nitrogen makes it shatter. I learnt a lesson that should not be repeated... Don't eat cryo cooled chocolate. When it shatters in your mouth it's like having a mouth full of cold knives. However after a while and some whimpering it did melt - so hurrah for melty chocolate!
I thought that was the idea behind Nestle's Don Carlos V. Ten years ago I bought some in Mexico and left the bars in the car but they remained solid. Also, this chocolate is not gritty and is available in the U.S. (At least in some markets)
That was the turning point of my life--I went from negative zero to positive zero.
There would be a lot of uses for a material that won't melt at high temperatures for example a heat shield for spacecraft reentry, or containment vessel for nuclear reactors
Exactly. I'm living in a tropical (African) country, and have eaten both Indian Cadbury's (they call it "Silk") chocolate, and the local stuff. The Cadbury stuff is better, but still not as good as, say, Australian Cadbury chocolate. The local stuff is cheap and nasty, but also won't melt in your pocket. All the imported stuff just gets really soft if you leave it out at room temperature. Room temperature here is normally about 25 to 30 degrees.
Personally, I just keep chocolate in the fridge. It just works. And if I'm going somewhere I don't have a fridge, I just don't take chocolate, there are heaps of alternatives for sweet thing.

Yeah, it's really too bad you didn't read the article. Otherwise, you'd look far more clever in your silence.

Life takes interesting turns, but the most interest is when you're off the beaten path.
Mmm yum. Better food through science...
It's interesting that we're suddenly seeing all these stories about engineered foods that don't behave like real food so soon after the collapse of Hostess. It's almost as though there is a perception that the world will be more accepting of new food-substitutes that last forever to fill "the Hostess void" and take the place of the Twinkie in our bomb shelters. Perhaps we will find that the new 60-day bread maintains a constant temperature of 105 degrees F, hot enough to ward off mold and melt the new chocolate, so you can have Nutella in your bunker. Because the comforts of chocolate offset the creepiness of bread that toasts itself.
To bring obesity to tropical countries!
If you look at a Hershey chocolate bar, it does in fact have "chocolate" listed in the ingredient list, which is by definition made from cacao.
Slow-melting chocolate vibrators. My idea. MINE!
I've calculated my velocity with such exquisite precision that I have no idea where I am.
They say, that their chocolate is going to be good even if it does not melt, as opposed to a "normal chocolate". As chocolate in general does not melt easily on very cold days and thus has taste problems, then perhaps their chocolate will actually taste better in the winter.
Who knew! I thought Cadbury just made disgusting sugar laden junk food.
That the US Army started issuing during WWII?

Hershey's tastes like brown paraffin wax.
I had a bar of Dairy Milk for the first time in a long while last week. It too was like wax. I suspect that quality has suffered since Kraft bought them out.
I stopped liking their mainstream products anyway - the cocoa solids content, at only 22%, isn't really worthy of the name "chocolate", but at least the mouth feel was OK previously.
They also own Green & Blacks, who produce some very nice everyday chocolate. Their milk starts at 34% cocoa solids, and they do bars all the way up to 70% and 80%.
Melted chocolate coming out of flat, squeezable plastic thing would be better than chocolate with strange chemical properties. For troops in the field, have an outer plastic wrapper so that they can put the inner plastic part in their mouth and squeeze out all the product without having to get dust and grime in their mouth. Oh, better yet don't make the inner wrapper plastic. Make it an edible product that's flexible but tasteless. How about gel caps full of chocolate? There would probably be too much gel though, and it might be confused as a medication. Of course there are M&Ms, but the hard shells crack and they still make a mess at high temperatore. I can't believe M&M Mars doesn't make a "battle hardened" version.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
How will scientists detect microwaves now?
I am an ACCA student. Got a query on Accountancy/Finance? Maybe I can help!
Hersey's gave us that stuff in Vietnam. True, it wouldn't melt, OTOH, it couldn't be consumed, either. The stuff was so bad that the rats would chew through a carton of cigarettes, crawl over the chocolate leaving foot prints and droppings, then continue with whatever else was available.
Pooping is overrated anyway.

Everyday chocolate. Now that's what I call life.
Through the entire article, and up-voted slashdot comments, not a single mention of the WWII era TROPICAL BAR?

Another Hershey purchase was Dagoba chocolates. Their 87% is excellent

GI Joe tossed you a salad, eh?
Cheese fits your description above. I don't eat enough of it for it to be a problem but I believe the answer is to blast it out by drinking prune juice. From experience, drinking four litres of unsweetened pineapple juice would blast anything out (it was an incredibly hot day and the stuff came in four litre tins so it was an entirely unintentional and disturbing discovery), but is not to be recommended since it leaves you feeling like you've had a sexual encounter with a Santa Gertrudis Bull lubricated with battery acid.
And here I was just thinking that they taste like that due to six months at sea in an oil soaked shipping container before they get to my country :)
I did some research ... well I googled "what's the funny taste in hersheys" ... apparently they infect the milk and let it sour to give the product that unique flavour. Now I can't stand off milk (except when it's so off that it becomes yoghurt), so that probably explains why I couldn't stomach Hershey's. It also explains why it tastes so bacterial.
Apparently I'm in a minority in recognising the overtones of throat infection in this delicacy. Most naive subjects (ie. those not raised since childhood to appreciate it's unusual appeal) seem to agree that Hershey's tastes like .... Though this is probably simply their initial revulsion and if they took the time to savour it the similarity to bacterial infection may become more obvious.
[BTW I'm using lmgtfy not because I think you don't know how to use Google, but for a little dramatic suspense!]
The reason I tried it in the first place is because I was told you could identify Proteus by smell prior to formal assay. It is said that they smell "like a cross between rotten fish and Hershey's bars" (the source for my incorrect "rotten fish" remark). Now I know why.
