random HP fanfic observation...
After reading a lot of Harry Potter fanfic with plenty of usually foul tasting potions (which of course wouldn't work with pleasant flavoring), it occurred to me that if I were a witch who had to swallow something like that, I would simply charm/spell my sense of taste/smell numb for a short time, thus avoiding the experience without altering the potion. Somehow it's strange that I've never seen that happen in fanfic.
