Who knows exactly why things suddenly become popular. You could blame it on the media (although, as of now, there's a one less media outlet to blame), or you could blame it on the power of suggestion—a chef sees something on a menu someplace, it lodges in his or her consciousness, and before you know it they've put it on the menu at their restaurant without even realizing. Think of it like seeds scattered in the wind, trends moving from coast to coast.
I am a huge hot dog fan, as many of you may or may not be aware. I grew up on them in New York and have spent a good portion of my life being ridiculously obsessed, so much so that I have even been tempted to tattoo a hot dog some place on my body. I have struggled with the absence of a delicious hot dog in San Francisco for the past seven years and I always look forward to repeated trips back home so that I can indulge … and there I was. Sitting in New York City, snowed in. Missed my flight back to San Francisco and got pretty much screwed. The only glimmer of hope was that I got to indulge in all sorts of delicious things to eat.
