In case you weren't aware, I like to play with chocolate.  A friend in San Francisco sent me this article, TCHO, San Francisco's high-tech chocolate, from Saturday's edition of the San Francisco Chronicle and I like it, so I'm sharing it.  (Thanks, Joe.) (Photo by Lea Suzuki of the Chronicle)  The article's about some new techie chocolate makers in San Francisco named Louis Rossetto (left) and Timothy Childs.  They're overseeing the process of true chocolate "making" from cacao tree to finished confection and seem to have great intentions.  I like their obsessive approach to food and want to taste their product!  Here's a link to the TCHO Web site, where you can order some and learn more about the company.
