A few days ago, my husband found this blog, called "The Language of Food". The author, Dan Jurafsky, is a professor at Stanford who teaches a course by that name about food and language across the world. One of the course requirements is to start one's own blog on the subject. (Regrettably, you need to have a Stanford computer account to access the student blogs.)
Though Professor Jurafsky's blog contains few entries, each entry is huge, and fascinating. The most recent entry is about what fish and chips and ceviche have in common, as well as a mini-history of their respective origins. It's fascinating stuff, and I recommend it heartily to anyone with an interest in food history, as well as linguists.
Now to go back and finish reading some of Jurafsky's entries.
