I had an argument with my friend the other day about the pronunciation of bechamel.
Everyone I know is pronouncing it like besha-mel. I've looked it up though and found out that the correct pronunciation is bay-shah-mel (according to Cambridge), which reports that the word derives from French. However, I've been told that if pronounced the English way it would sound like the former beh-shah-mel with the 'sh' sound, which I do not agree with since I'd pronounce bech- with a 'k' sound.
As far as I'm concerned there's no rule regarding this; it's one of those things you have to learn and memorise (see this thread), but I'd like to know if the English (incorrect) pronunciation of bechamel would sound like beh-cah-mel with the 'k' sound or the previously mentioned 'sh' sound.
