I had a lunchtime conversation today about the correct pronounciation of jicama. I have to conclude that I had never heard the word before, at least not from anybody who speaks Nahuatl.
Fortunately for my ego, which bruises about as easily as a bland starchy tuber, I got to school someone later on the correct pronounciation of quinoa. And I was ready to go head-to-head if anyone asked me about haricots.
