I love Marmite too much to use it as a mere bad taste suppresant.

I think a fizzy drink was most helpful, a fruity one.

I have three more candy bars that I can't bear to think of at this moment.

The other more recent thread about chocolate was what I was thinking of, thank you, but it didn't really refer to the specifics of the difference in chocolate taste between U.K. and America. But there are some interesting internet articles on the difference which I may get to when I can get the memory of the taste out of my mouth.
