A really interesting program on SBS tonight; Heston Blumenthal trying to improve the food on BA (please no bombarding me with bricks, I've only flown them once and can't remember the food). He firstly checked out the food and thought it was cough; didn't bear much resemblance to the photo of the dish (and I missed the start but think it was in Economy) He worked his way up the food chain and didn't get any more impressed with the offerings in F. His plan was to design a menu which would taste good. So rather than have the stuff prepared on the ground he'd do it on the plane. Train wreck. Then he thought he'd just do a cold version of a bento box for the first class passengers - that made meal service 1-1/2 hours late!
However he was intrigued with what happens to the food and wine when it's 30,000 feet up and in the very very dry conditions in a plane. Why couldn't it taste good? He got the exec chef of BA to do a blind testing of the five flavours and discovered that salt, for instance, tasted about five times less salty. Sugar had a similar result. He discovered that the one thing which was not altered by altitude or dryness was (not too sure exactly what it was called) umami which is a component in soy sauce, nori, worcestershire sauce, etc. Parmesan cheese was another. He reinvented Shepherd's Pie, putting the cheese in the mashed potato and the other stuff in the meat mix and both the passengers and the BA tasting panel raved about it.
I've never watched his shows but it was fascinating to see how his mind was shooting off in all directions to try and solve the puzzle.
Oh, one of his suggestions to improve one's sense of taste was to restore humidity in the nose by using a nasal douche. Truly disgusting! It'll never catch on. But an interesting insight which might explain why some airlines serve cough food. Maybe - some airlines just do serve cough food
