We don't know, from Vampires alone, whether this object is called a boiled sweet. It should be pointed out that "boiled sweet" is a very general, Br. Eng.-only name, and it may not even have been what the Doctor gave her. I would imagine there may well be a reference to "boiled sweets" somewhere in some story, but it's not here. Until and unless we get absolute confirmation of that, though, this is a conjectural title, and I'm really not sure there will ever be a point where we can confirm that he actually gave Amy a boiled sweet in this episode, so the language here is going to have to be moderated to "what appeared to be a boiled sweet", or something similar. It should be pointed out that in the past — on television at least — the Doctor's use of "boiled sweets" has been rather more specific. He called what he was eating in The Wheel in Space a "lemon sherbet", for instance. CzechOut | 18:58, May 10, 2010 (UTC)

The example from the Decalog story is prose, and was indeed referred to explicitly as one of the Doctor's "striped boiled sweets," so I think the title is okay based upon that. The language on Amy's example, on the other hand, can be suitably changed. Rob T Firefly 23:21, May 10, 2010 (UTC)
Its clearly a Humbug, which is indeed a boiled sweet. http://en.wikipedia.org/wiki/Humbug_%28sweet%29
