Oh, LORD! Gordon usually corrects people that say MacarOOn, doesn't he? Even HE is saying it tonight and it's driving me crazy! The lady baker is the only one saying it correctly! Now, I never even HEARD of Macarons till a few years ago (on Masterchef, coincidentally) and I've never tasted one, but even I know how it's said!
I read somewhere that on both Master Chef and MC Jr. in between shoots a lot of time is spent in cooking classes. However, the challenges are not revealed to the contestants before the actual competition.
