I don't know if there's really a specific fandom food, I was just kind of vaguely thinking about when people come up with recipes that are inspired by some kind of food that a canon will mention. So I'm not sure how related that is; since it's not a group activity, it may not qualify as -- as fandom-related as, say, a fic or a wallpaper. (Then again, there are Harry Potter- and Battlestar Galactica- and Red Dwarf- and Bones- inspired knitting patterns, too, so -- I'm not sure how much that sort of thing qualifies as a fandom activity, rather than something that's purely done "by fans." Those are just the patterns I could think of off the top of my head, BTW, not to say that knitters who are fans don't do other fandoms.)

I have been looking back at the 2009 14 Valentines round-ups all afternoon and am fascinated. Not by the fic, since I'm not really reading at the moment, but by the icons and the music and the essays, and -- well, it's me, the recipes and the knitting.
