Trying to make this into a word post, Shu, I looked chocolate up in the OED to see if I could find anything linguistically interesting, and I couldn't. However, I found this very nice quote from from the Sunday Glasgow Herald (Electronic ed.) 1 Apr., 2001: "There's nothing better to warm the cockles than a really good soup, a spicy curry and - for sheer chocoholic indulgence - a smooth dark chocolate tart."
