I was bought up at a time when you HAD to eat everything that was put in front of you - it was a punishable offence to leave anything, 'think of all the starving people in the world'...!!!
As a result, I find it really hard to think of ANYTHING I dislike, except coconut - then it's not the flavour, it's the texture of the stuff! A Bounty Bar (don't even know if they still exist!) would be totally inedible! I could probably manage to eat the chocolate off the outside though, if I could wash it first...!!!
