  D:Yael, do you know what's the best thing about state affair?

Y: Do you tell.

D: Fried candy bars, two favoriate treats rolled into one. And doesn't it bother your mind how they manage fried chacholate without making a terrible mess? Fried candy bar must be made with magic, I tell you.

Y: If you consider chemistry magic, then yes, fried candy bars are products of magic. But if you know a little bit of chemistry, how the strange treat is made isn’t exactly mind boggling. Chocolate’s melting point, like anything else, is determined 1 by its chemical ingredients. Composed of about thirty percent fat, most chocolate bars begin to melt at just a little below body temperature, about eighty-six degrees Fahrenheit 2.

D: Surely the oil and frier is a lot hotter than our bodies.

Y: I was getting there.  Yes,the oil is indeed significantly hotter than our body temperature. But here’s the trick. First, the bars are refrigerated so that they take a little longer to reach their melting point when they come into contact with the hot oil. Then there’s the batter 3 composed of flour, water, eggs, and sugar. The individual proteins in the batter come apart in the heat and then they rapidly link up together to form a protective coating around the chocolate.

D: I see. By the time the chocolate starts melting, it’s safely contained within its fried coating. Then the fried candy bar is removed from the oil to cool, the chocolate solidifies 4 again, and you have yourself a delicious treat!

Y: What's mind boggling about it are the calories.

D: Who asked you.
