I suspect that what was really annoying about the Senora was that she wasn't just ignorant. She was also complacently and self-congratulatory parochial. Clearly those stupid Arabs and Berbers (if she's heard of them) didn't know how to cook until the Spanish showed them.

To be fair, she's probably no worse than most. Everyone assumes that their culture is superior in every way until they learn otherwise. It is the default mode for the human race. That doesn't make it less annoying, of course.

Now and then parochialism can be amusing. I remember giving guests of mine a drink of blackcurant juice. I consider it to be an English drink because I learned about it from my English mother. My Jordanian guest was surprised and pleased that I had given him a Jordanian drink, and my American guest (who had been to Egypt) wondered where I had got an Egyptian drink from. I have since then been told that it is an Indian drink. Well, I don't know who started it, but I suspect that the British and their empire is the common thread.
