Bryn Dyment, a Web developer in the Bay Area who grew up in Canada, said he was shocked when his parents took him to a candy counter in the United States. He found out that not every child in the world was eating the same chocolate bars he was.

It wasn’t until he moved to the United States as an adult that he realized just how vast that divide is.

“You get in these religious arguments with people,” he said. “I haven’t met a Canadian who likes a Hershey bar, but Americans think you’re crazy when you say that, because they think everyone loves a Hershey bar.”

“Hershey’s tastes like ear wax...”

I agree whole heartedly. While I am in most respects an American one aspect of me which will always and forever be Canadian is my taste in chocolate. My two great disappointments upon moving to the United States at the age of nine were learning that your Cheerios are made with whole wheat, and learning that basically all of your candy bars suck. Nearly everywhere else in the world that I've travelled to, from France to Hong Kong, has English chocolate like Smarties and Aero Bars on the shelf. For a long time I'd thought the reason Smarties weren't available here was due to a trademark conflict with the rolled up sweettarts popular at halloween, but this doesn't explain the fact that no other English candy is available, or if, like Kitkat, it is available, the recipie has been screwed up. Something is deeply wrong with American taste buds.

I'm disappointed that this article, while finally putting the honest truth in print in the United States, fails to delve into the details of why. However, I have a hypothesis. I'm not sure when candy bars first became popular but there are only two possibilities:

1. They became popular before the revolutionary war, in which case Canada and the United States should have both inhereted the same taste in chocolate from England.
2. They became popular after the revolutionary war, in which case you'd think Canadians and Americans would have started eating chocolate manufactured in the same way, and that while English tastes might have diverged, Canadian tastes would have tracked American tastes and not English ones.

Neither occured. So, my hypothesis is that in the beginning, American and Canadian tastes in Chocolate tracked English tastes, and then this funny thing called World War II happened. During WWII Hershey got a contract with the US Army to distribute Hershey bars to American GIs. These bars were designed to have a high melting temperature so they could be handled by Army logistics easily, and be sour enough that soldiers wouldn't eat them when they weren't supposed to. Soldiers came back from the war with an endearing relationship to Hershey, and a taste for flavorless bars, and so now everyone in the country is eating the chocolate equivelent of MREs.

I have no idea if Canadian soldiers were issued chocolate during WWII, but as these flavorless candy bars were an American invention its likely that whatever they had, it was different.
