Those white mice (not sure they are white chocolate) are vile. Them and the white buttons with sprinkles on them were about the only sweets I didn’t like as a child.
The only sweets I actually disliked as a child were anything with coconut in (still don’t like Bountys) and turkish delight. Not hugely fond of Ferrero Rocher either.
Oh, I forgot another candidate for best sweet: cola bottles, but only the ones that are quite thin and floppy, but very nearly see-through, which you don’t seem to get these days now that Haribo have taken over the world. And a plus one for Wham bars, when they were A4 sized (as it seemed to me back then)
