Adam Gopnik has a cool (and surprisingly brief) article in this week's New Yorker on the role of food in literature. I like how he categorizes the way food is used as a literary device. I also like his discussion of recent literature using cooking as a mindless activity, meant to set a scene and be in the background as a character has deep, revelatory thoughts.
Gopnik obviously thinks about food a lot. I'm glad he's been writing about it more lately.
