I posted this over in
fanficrants and
longlongwaytogo suggested it might be a good idea to post it here as well, so here it is, slightly edited for later developments. :-)
OK, I know the canon has ghastly glaring anachronisms (sandwiches at Camelot? WTF? [1]), but it still sets my teeth on edge when I see a fic based around Merlin bringing Arthur hot chocolate, since the stuff didn't gain popularity in Europe until the 1500s. Wouldn't have been so bad if it was a passing mention, but it was central to the story. Also, it's referrred to as something Merlin had at home in Wales and Arthur was completely unaware of, which seems the wrong way round; if a shipment
had somehow made its way across the Atlantic way ahead of schedule, you'd expect it to have come to the larger urban areas first
[1] Actual sandwiches wouldn't necessarily be a problem I suppose, but one of the characters explicitly
calls them that in one episode, several centuries too early...
ETA - just to clarify, I'm talking about the currently airing BBC series "Merlin" here. Other versions of Merlin may have access to/be aware of chocolate. I'm fairly sure this one doesn't. Or at any rate, shouldn't. (I added this because people weren't sure which version of Merlin I was talking about)
ETA 2:- So, as at episode 7, we have potatoes in canon. I give up. Clearly the canon writers have no idea about food in medieval England either...
