Here's an excellent article from the New York Times on the gum tasters at Cadbury. It brought back such lovely memories of my time as one of their beverage tasters. What a great job that was. The training was so much fun, learning to tell the difference between candy strawberry, fresh strawberry, strawberry Jell-O, cooked strawberry, strawberry jam ... my palate will never be the same! I don't think I'd like to be a gum tester, though. Too much chewing. I'd imagine your jaw would hurt after a full day's work.
