UK Candy Recommendations?

This afternoon, I’m flying to London, then busing to Cambridge where I will spend the next two weeks (I get to be a research assistant for the Autism Research Centre. Hooray!). I’m excited, of course, since I’ve never been to Europe before.

Any particular suggestions for candy to check out while I’m on the other side of the pond? So far the only must-taste on my list is Thornton’s Chocolate Smothered Toffee, which Melanie Dunea of My Last Supper authorship told me she would have for her last supper.
